“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.”

“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.”

“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.”

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 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.”
“They did insulation work in my old house. I give them an A.”
“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.”
“They insulated my crawl space. It was a good experience. They came in there, they were clean, they got the work done, and they left. I'd recommend them.”
“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.”
