“Garland reinsulated the house. I liked their efficiency, the fact that they cleaned up after themselves, and the speed with which they did their work. They were very efficient and very good. I'd give them an A+++ across the board.”
“I was very satisfied with their work. They sprayed insulation in the walls and out to the deck. I'd give them an A+. They told me every step they were going to make. They showed up exactly when they said they were going to, and they got it done in the time frame they said they would. I'm thinking about getting them to do more work.”
“They did a very good job. They sprayed insulation. It was a nice, easy process. I'd give them an A+, overall. I'm sure I would recommend them.”
“They installed insulation. They had good service. They're an A.”
“They just sprayed insulation. I asked them to come back because they had covered up some lighting fixtures. It was no problem. They came right back, fixed the problem, and that was that. I'd give them an A+. They kept things pretty clean. I'd recommend them.”

All of my jobs are restoration jobs and remodel jobs. It's got to be timely. I'd give them an A overall. I don't think I've ever had to call them back on anything. I get somebody, and I just stay with them.”
“They installed insulation. They just came, sprayed it in, and left. The sales guy was pretty helpful. The experience was an A.”

“They were awesome. We really enjoyed the experience. Everything was good. Their customer service techs were very nice and professional. The quality of the work was great.

They did a great job. They were fast, easy, and clean. I had a very positive exchange with them. I chose them over a different company because of their customer service. The person I worked with is very good; she always does what she promises, and I will keep being their customer. I'd give them an A+ rating.”

“They were very quick. They cleaned up after themselves, and it was just easier than I thought it would be to do that type of job. They insulated an investment property that we have, so they did a shared wall for some condos. I used them again when we had a vacancy, and they did another wall. It was a pretty big shared wall that they did on two floors. They did it very quickly, and it didn't seem like a big job at all for them. They're very responsive. They really try to accommodate my schedule, and I would use this company again. They were recommended to me by a contractor; I just went with them because it was a reference from someone that I trusted. I'd give them an A.”

“They did a good job.”
“I'd give them an A. They were great.”
“They were on time. They cleaned up well. They did what they were supposed to do. They put insulation in my attic. They were just real polite and customer oriented. I chose them over a different company because I've used them two times before. I'd grade Garland as an A.”

“I had some insulation done a year ago. They were very professional. They are on time, and they did the job quickly. The insulation is still there. I talked to another company and Garland Insulation, and they just seemed to be the most professional in the way they handled it, so I went with them. They did the attic for me. I'd give them an A because in my mind, everything went fine, although it has been a while.”
“This work was done a while back. They did insulation work for me through the whole house. I had no problems with them. They were good for me.”
“They seemed very organized. They came when they said they were going to come. There wasn't a long delay or anything like that. They were in and out. They did the entire attic, which covers the entire area. It's a single-story house. I'd give them an A.”
“Garland Insulating did a good job.”
“I liked the representative that came out. He didn't try to push anything extra. The guys that came out and did the work were real friendly. They didn't make a big mess and didn't leave a big mess. I got them out of the Best Picks book for my area. They sucked out the old insulation and blew in all new. I'd give them an A.”
“They were on time and did the work I expected. I chose them because somebody referred them to me. They put insulation in the whole attic, and it took a couple of hours, tops. The customer service was good. I'd give them an A.”
“It was fine.”
“They didn't waste any time putting a price together, and they got right out and got it done. I had them add insulation to the attic for the whole house. I chose them over a different company because the name Garland Insulation has been around for a while, and I already knew about them. I would grade them as an A.”
“They were on time. They were quick with their work, and the work seems to have been good quality work. They were recommended by my roofing company. The job was fairly small. They just blew in additional insulation in the attic. I'd give them an A.”
“Garland Insulating is absolutely wonderful—everything you could look for in a company. They are neat and clean. The thing I liked the most was that the man gave me options and didn't pressure me to take a useless one. Certain houses don't need as much insulation as others, and I would not have known that in the least. They've earned an A+ grade.”
“Working with Garland Insulating was top-notch. They were knowledgeable and timely, and they did it right. They did foam insulation in the attic and walls, and the representative was really nice and really trustworthy. I would give them an A+.”
“We have used Garland Insulating several times over the past 25 years. They've always done an outstanding job, and the quality and service have always been the same—outstanding. Word-of-mouth advertising is the best, and they've got it. They're A+.”
“Garland Insulating provided insulating needs for the home. They do all of our work. I'd give them an A+.”

“Garland did some foam and some cellulose insulation for me. I chose them because of their performance and service—A+.”
