“Everything was great with Southland. They were on time. Everything went as planned. They insulated my basement with the blue cell stuff. They took off siding and sprayed inside the wall cavity. I'd grade them A+.”

“I had some insulation work done earlier this year. Everything about it was positive. They put insulation in the attic and sealed up my basement—sealed up all the outside holes. They did a great job. I had no complaints at all for any of the work. I'd give them an A+.”

“I had them rearrange and add insulation to my attic. They did a good job with that. They added insulation—originally, we wanted them to move the insulation that was up there and put it underneath the floorboards. Instead, they put new insulation under the floorboards and moved the insulation that was there to make better use of it. They're A+.”

“Southland did blown-in insulation in the walls and the attic of the garage that we have attached to the house. They did the job in the time they said they were going to do it, and the insulation was the right quality. It kept the garage warm and that's what I was looking for. I'd give them an A+. There were no issues.”

“They added additional insulation into my house. They made it a very easy process. They came in, gave me flat-rate quote, they raised up the amount of insulation to how much I asked for, and they were in and out within a few hours. I can definitely feel the difference in my home. I'd give them an A+.”

“They came by and insulated my attic. They came on time. They were extremely neat in what they did. There was no mess. They did the job and did a thorough job—showed it to me when they were finished, asked me if I had any questions, cleaned up outside and they were on their way. They get an A+.”

“They did a spray-in insulation in our crawlspace. It was easy. They explained everything. I was very happy with their product. They get an A+.”

“They re-insulated our attic and over our bedrooms, which is the first floor. It made it much more comfortable. I'd rate them A+.”

“They re-insulated the attic for me. They did a good job. They were efficient, quick, showed up when they said they were going to show up, and finished when they said they were going to finish. I'd give them an A+.”

“They upgraded the insulation in my attic, and they also put an attic cover over my access door that went from my second floor up into the attic that has a zipper so it's really fully insulated. More importantly, I think that when I asked them to come out and do a quote for me, because I was checking with some other folks, they did a really good job of explaining why they wanted to recommend I do made sense and it made sense to me. Their sales rep was really very knowledgeable about what was going on in my attic and why what they do could make a difference. Prior to that, when I had my home built several years ago, he told me it made good sense to put in some attic fans that were powered by electricity. I don't know how effective they were but over time they stopped operating—so when I asked Southland what they thought about them, they said I should have never had them in the first place because the type of roof I had is designed to allow excess heat to go out on its own. What I really need is a stronger barrier between my attic and the second level. They did a really nice, neat job. They came in one day, had a great crew, had all the right equipment, did all the home prep to make sure the house was not going to see any unnecessary attic insulation or traffic from them being there. They knew what they were doing. They're definitely A+.”

“They were very nice people that I dealt with the entire time, including the sales rep. They re-insulated my entire attic. I could see an unbelievable difference this summer and last winter. It's quieter in my house, I could see a difference in my energy bills, and it was just warmer upstairs in the winter. This is hard to believe, but my upstairs is cooler this summer than the downstairs. I would rate them A+.”

“They're great. Great service. Great product. They get an A+ across the board.”

“They've done a couple insulation jobs for me on a few houses. One of them was they did the entire house, the walls, and the attic. Then the other one, the last one that I did, they put it inside the crawlspace for me. I've used them several times and they've been really good for me. I'd rate them as an A.”

“We had them reinstall some insulation under our crawlspace. That's an area we do not want to go, and they did it with no hesitation and did a great job. They're an A+.”

“They did additional insulation and sealing for my attic. They were highly recommended.”

“My experience with this company was positive.”

“My experience with this company was positive.”

“I called them because I wanted to get an estimate as to what it would take to lower my gas bill because I was spending a tremendous amount of money on my gas bill. Someone came out and explained to me what it would take to insulate my attic. They helped me reinforce the door to my crawlspace. They helped me fix some insulation in my crawlspace. They were really helpful. The guy who came out had obviously worked in the home-building space for a really long time. He was very nice, incredibly intelligent, knowledgeable, and trustworthy. They helped me solve the issue. I can feel a difference in the overall warmth of my home. I think there's been a minor decrease in my gas bill but the biggest thing I've noticed is in the increase of warmth in my home in the winter. I'd give them an A.”

“I could tell there was airflow that was unnecessary and the house was flooding in certain areas from the HVAC, so they did all the work. Basement, interior, and exterior work. They did some insulation. I could feel the difference immediately. They get an A.”

“I had just moved in to a house that had been occupied by the same people since it was built in 1949 so I wanted to get new insulation. They took out the old insulation and put in the new one pretty well. They did a good job. I'm satisfied with the product. The only thing that surprised me is that it's so thick, they had to put up these partitions at the edge of the floor. It's probably a foot or more above. I didn't expect that. I didn't know it was going to look that way—That's the only thing that's frustrating. They insulated above the second floor ceiling up in the attic. They get an A overall.”

“I had my basement insulated. In my basement, there's a crawlspace—I had that insulated. There's a bedroom above it. Then I had my attic insulated. They were both A work.”

“I thought they were fantastic. There was a crawlspace next to the kitchen that was totally uncovered. They completely covered and sealed it. They completely insulated it to cover all the stuff and fix the walls, and it's great. I'd give them an A.”

“It was an awesome experience.”

“It was pretty straightforward. They blew insulation into my attic and did a pretty good job keeping the mess down in other parts of the house. I'd give them an A.”

“I've used them a few times and they're very proficient. They showed up and did exactly what they said they were going to do. The work was done very well. The homeowner was happy. It was an overall good experience. I contracted them to do it for someone else. I saw the finished work. It was an A experience.”

“Southland insulated over my garage and blew in some insulation. They were professional, easy, and got the job done. I'd rate them A.”

“Southland put in the insulation. They were nice. And they lowered our energy bill. They made our house more comfortable. They insulated part of the house. It's an old house, and there were spots that needed to be insulated. They re-insulated, basically. They get an A for everything.”

“They blew in some cellulose insulation above the second-floor ceiling. They also sealed the top of the walls that touch the ceiling on the second floor. I've seen a difference in energy bills since it was put in. I'd grade them A.”

“They did foam insulation for me because they had a pump and they pumped it in. They came on time. They did the work. They cleaned up well after they left. I'd give them an A.”

“They did insulation in my attic, and I'll give them an A.”

“They did the attic. They removed all the old stuff and put the new stuff in. They did a crawlspace encapsulation and everything's fine. They used fiberglass in the attic. I'd give them an A.”

“They installed attic insulation, which was the recycled paper material, cellulose. They also insulated the space above my garage and also the space above the family room which was accessible to the garage. They did two main jobs. I'd give them an A.”

“They insulated a ceiling, an attic, and an exterior wall. They used an open-cell insulation, spray-foam. I'd give them an A overall.”

“They insulated my basement with blanket insulation. They did it very efficiently, very cleanly, and they did a good job. I can feel a difference in my home. They get an A.”

“They provided me with insulation in our attic. They sealed some of the ducts. Overall, it was positive because they came in, gave me an estimate on time, and when they did the work, they were on time, very professional, and took care of business. They get an A.”

“They put attic insulation in for me. They used fiberglass. I'd rate them A.”

“They replaced all the insulation in my attic. I'll give them an A.”

“They sealed my attic and then added insulation. I'd rate them very good; I'd give them an A.”

“They took out what insulation was in my attic, sealed the attic, and then replaced some and added more insulation. It was very simple. Everybody was very nice. They showed up when they said they would. I'd give them an A.”

“They were fast, and they were efficient. They had a couple different product offerings, and they explained them well. I think we made the right choice. They were very good. They insulated a room over a garage. They used two different types—it was compacted material blown in the floors and then just batten put in the roof/ceiling area. They were an A; I was very pleased.”

“They were great. They insulated a whole bunch of things for us. We were satisfied with the work they did for us. I'd give them an A.”

“I had a positive experience with Southland Insulators.”

“They did some work for us. They encapsulated our crawlspace under our house, which basically conditioned it into a living space. Obviously, we wouldn't live in our crawlspace. It gives us better air quality in the house and is going to preserve our heating and air conditioning unit under the house as well. I would give them an A-.”

“Southland had outstanding workmanship, and they really cared that I was happy about the work. They were doing insulation and air sealing. I would rate them as an A+.”

“They did really good work. The workers were clean, neat, and honest. They did insulation work for the attic. They get an A. They were excellent. I would recommend them.”

“My experience was absolutely positive. They cleaned up behind themselves, and they were very efficient and professional. Someone even came out to check the work. They did an excellent job. They took care of all the air leaks. I'd give them an A.”

“Southland Insulators did a great job. They were very professional, and they did what I asked them to do. They were very accommodating. Very pleasant experience. I'd use them again. They did insulation work for me, and they earned an A+ grade.”

“Southland Insulators did a fine job with our attic insulation. Overall, they were excellent, and I have no complaints. I felt they were very good, and they had to work by walking through the house on my white carpet, and everything was as it was when they came—perfect. I'd be extremely likely to recommend them.”

“I did have a very positive experience. The work they did came out great. It was excellent. I had no complaints across the board.”

“Everything looked perfect. There was no problem. They did insulation for me. I'd give them an A grade.”

“I'd give them an A, and I'd recommend them very highly.”

“They did what they said they were going to do. It was insulation work. I would say it was excellent. They deserve an A grade.”

“They glued in some insulation in my attic. They did a good and efficient job. They were clean in what they did. They put carpet protectors down on their way up into the attic. They went over and beyond and fixed my attic door so that it's not so hard to open anymore. I think they did a good job. They get an A+ from me.”

“I liked their professionalism; I would say that would be the number one thing about them. They did insulation for us, taking out old stuff and putting new stuff in. I'd give them an A+ rating.”

“They worked on our attic. They were an A.”

“Southland Insulators did a very good job. They put in new insulation and floored the attic. They were very quick in arranging the work to be done, and they were very clean. Insulation is kind of messy and dirty, but there was no mess at all, so they did a great job. I'd give them an A. I've already recommended them.”

“They were clean, efficient, and got the job done well. They did some insulation in a small portion of the attic and some insulation in the basement area where the basement and first level meet. I would give them an A.”

“This was like a year ago, but I remember they were very professional. They came in, they did what they had to do, and they cleaned up. I'll give them an A. I'd recommend them, too.”

“They did the job they said they would. They did insulation. I would give them an A.”

“They did what they said they were going to do. They did insulation. They deserve an A.”

“They were efficient. Southland Insulators moved throughout the house, and they didn't leave a big mess. They seemed to do a good job. They sealed the attic and put in insulation. I'll give them an A. I'd recommend them. I've only done it once; they're the only ones I've used, so I wouldn't know who else to recommend.”

“They cleaned up very well, and they did everything that I wanted them to do. They actually got two jobs out of one, after doing our insulation. I'd give them an A overall.”

“They did household insulation. They get an A from me.”

“They were very friendly. They cleaned up after themselves. Their work was very successful—my house has been very warm. They did insulation in the garage. They earned an A.”

“I don't know if anything stood out. I had some insulation work done over a year ago. I'd give them an A.”

“I had some insulation work done by Southland Insulators, and it was very good. They were on time, conscientious, and did a nice job. I'd give them an A. I would recommend them. I got them through a recommendation, so I wasn't sure who they were, but they did a very nice job, and I'd be absolutely likely to recommend them now myself.”

“My experience was definitely positive. I've used them a couple times, and when I scheduled my appointment, everything was on time. They were fast, they cleaned up properly, and everything went well with the insulation work. I grade them as an A.”

“They did their job as described. They were doing insulation. They deserve an A.”

“I definitely had a positive experience. I'd say they're an A.”

“They were very polite and kept their work area clean. I'd give them an A grade.”

“Southland Insulators did some insulation for us. I had to call them for an adjustment, and they came back and redid it. For that, I'd give them an A, and I'd definitely recommend them.”

“They were pretty neat. They got in and out, and they got the insulation installed pretty quickly. I'd give them an A.”

“It was a great job. They came and did what they said they would do, and then they left. They cleaned their mess up, too. I'd rate them an A.”

“Southland Insulation did insulation work up in the attic. My experience with them was very positive. They were fast, efficient, and my house is so much warmer or cooler—whichever way you want to look at it. I give them an A.”

“My experience was absolutely positive. They came in and did their work. They were professional and kept the place clean. They did some insulation work for me in a house that was under construction. I would give them an A grade for sure.”

“The insulation they did in my attic was done on time, on schedule, and they did it for the price they quoted me. I'd give them an A.”

“They were very quick, they were on time, and they were extremely clean. They insulated my attic and the space underneath my sunroom addition. They did spray foam and filled the space. In the summer, it hasn't been as hot upstairs and in the sunroom. I would recommend them. I would definitely give them an A+, for sure.”

“Southland Insulators did a real good job. They insulated my entire ceiling. It took a couple of hours. They did an excellent job, they cleaned up after themselves, and they protected all of my house.”

“We did use Southland Insulators, and it went well. They did as advertised. The technique they used in the upper garage was to poke holes in the wall that shared the other side of the master bedroom, spray insulation, and fill it in. Our bedroom doesn't have cold air coming through, and it's not burning up hot now in the summertime. It was effective. They deserve an A. It was the best-case scenario—it worked out well.”

“I would rate Southland Insulators high on everything. I was pleased.”

“It was really good. They were very careful, they were very clean, and they paid attention to what they were doing. The supervisor was very aware of the little idiosyncrasies in our home. It was a really positive experience—I would hire Southland Insulators again. They blew insulation between our first and second floor. They were recommended by a remodeler we know that we trust. I think they did an A-rate job.”

“I liked that the technicians came when they said they were going to and charged what they said they were going to. They insulated an attic. Their customer service was fine. I've used them before. They were excellent.”

“What stood out to me was specifically that the gentleman we worked with had good knowledge of using a hybrid of foam in a conventional spray insulation. They did our basement band boards in our old, 1890s home. It was an old section of stone wall, and they also insulated better in our attic. Cooling our house, we have noticed that the air conditioner isn't kicking on as much. We would recommend the gentleman we worked with. We have an 1890s construction, and he was able to understand which insulation solutions were best for our existing structure.”

“They did a great job. Southland Insulators did fantastic work.”

“Working with Southland Insulators was positive from the beginning—their quick return of my phone call, the scheduling, and the on-time arrival to do the work. They accomplished it in a very quick time without any delays. They were just a very professional company to deal with. I've had them out twice over the past few years. One job was the main attic, and one was over the garage. Then, I had a wall insulated in my family room. They're an A+ service.”

“The people from Southland Insulators were very professional, timely, and knowledgeable. They insulated our attic, and I would call it A-rate work.”

“Everything was fine. I would rate them as an A.”

“Southland Insulators insulated my home—the wall and the ceiling. It's an A grade from me.”

“I was really happy with the work. They insulated the attic, and they did fine. The customer service was good, too. I would give them an A.”

“I had a positive experience with Southland Insulators. They installed insulation in the attic and insulated around the foundation. The workers were clean and on time. I call that A work.”

“I liked that it was quick, and they were clean. The work that they did made a big difference in our house. They put some insulation in our attic. They move quickly, I guess, in terms of scheduling. Once I told them the work I wanted to do, they set up a time pretty quickly. I heard about them from our neighbor—her son is an engineer, and he approved the stuff they were blowing into the attic. I'd grade them with an A.”

“I liked the quality of materials Southland Insulators used, the ease of scheduling, and the professional staff they sent. They did an overall great job helping me with the energy efficiency of my house. They insulated my attic as well as an overhang in the back of my house. I heard about them through a real estate agent friend of mine who recommends them to her clients. I also used the eco-friendly materials. They're definitely an A.”

“They were efficient, they did the work, and I really had nothing to complain about. They installed some insulation above the garage for me. The guy that came out was quick to come out and give me an estimate. I believe I chose them because they were the first ones who called. I was looking to get it done quickly. I'd give them an A.”

“Southland Insulators did what they promised. They get an A.”

“I had a very positive experience. I liked them very much, and I will use them again. I'd rate them as an A—they were very good.”

“They seemed to know what they were doing and the services that they were providing. They insulated under the crawl space area. I had very limited interactions with them, but they were polite. My neighbor told me about them.”
