“An Exterior did an excellent job. I'd give them an A for excellent work.”
“An Exterior did some replacement and some repair of HardiePlank siding. I found out about them from the Best Pick Reports. I was, frankly, having trouble finding anyone. It wasn't a very big job, but An Exterior was quite responsive, and they did some nice work, I thought. It was a good recommendation. I'd tell anyone to definitely get a quote from them. They're punctual, and they did their work quickly. I watched them, and I think they did a very good job, so I'd say to certainly consider them for a job that involves siding. They're A+. I had no issues with them.”
“They came out quickly and took care of the problem, and I didn't have any issues with the quality of their work. They did aluminum siding replacement and gutter replacement. A friend recommended them to me. I'd rate the company as an A.”
“They did a great job. We had a portion of the siding put on, and they did a really good job. We had a bay window that was wooden, so they wrapped it. They fixed the rotten wood, wrapped it, and did the siding. My neighbor told me about them. The company gets an A.”
“When I need them, I'm going to call them again. They did a lot of things. They did painting and the siding, and they did a good job. I'd give them an A grade.”
“I had a good experience with An Exterior.”
“An Exterior was stellar. They were A-1, period. They did HardiePlank siding on the back side of my house, and their workmanship was incredible. I would absolutely recommend them. They also did the gutters, the roofing, and the flashing, and they knew exactly what they were doing. They're a killer contractor. They deserve an A+ all the way around.”
“The siding repair was more difficult than was visually apparent, but they were able to follow through quite easily. They had skilled workers. I even used them for some siding issues at my daughter's house, so I'd highly recommend them. They're A+.”
“All aspects of An Exterior's work were very good, but I was especially excited that they left everything so clean. Everything turned out very well. They put siding and a new roof on. They're a very good company, and I would give them an A+ grade.”
“We had some storm damage, and An Exterior showed up and got the work done. It was a small job, but I would recommend them. We had used them, I believe, in the past to do all the siding on our house. I wasn't here when they did the work, but their customer service was fine. I give them an A+.”
“They replaced our garage door, and it was great. The workers were very nice. In fact, the owner came out. We'd used them in the past to repair our garage door. I would give them an A+ rating—it is even quieter than it was before.”

They were very nice and responded much quicker than anyone else did.”
“An Exterior was terrific. It was nice craftsmanship and quality work. We needed to have the siding replaced, and even though our siding was no longer being produced, they were still able to locate and match it perfectly. The technicians explained everything thoroughly, and they cleaned up well. I'd absolutely give them an A+.”
“An Exterior was very neat and very clean in everything that they did, and the quality of the work was excellent.”
“An Exterior did a great job. I had storm damage, and they did siding work for me. They did good work, and we're going to call them the next time we need work done.”
“I've been using them for three years. They've done siding work for us, and the workers are good. They're an A+ company.”
“They were fabulous. I would give An Exterior a glowing recommendation. They did the HardiePlank siding on our house, and I have nothing but positive things to say. They told us how many days it would take, and they did it in that matter of time—that included working straight through on a Sunday. They were professional and neat. I rate them an A+.”
“An Exterior was in Best Pick Reports, and I had a very positive experience. They were extremely friendly and quick with their service. They replaced some siding and flashing on the roof that was missing. It was quality service. I'd say they get an A.”
“I'm very happy with the work An Exterior did. They were very quick—they took care of the work right away. They repaired a couple strips of siding after a storm, and the quality of the work seems to be spot-on. I wasn't there, but I had tenants there, and they said the technicians were quiet, very efficient, and got the job done right away. I'd say go with them. I'll call them again. A+.”
“They were really good. I tried calling other companies, and no one was available to come and put in the siding before it started raining again, but An Exterior was very accommodating where other companies were not. First, they patched it, and then, in another storm, the other siding came off, and we asked them to tighten all the nails, and they did. I think they did a fine job. A+ for them. I'd call them again and recommend their service.”
“They completed the work really quickly and did the job that I asked them to do. There was one aspect that wasn't properly repaired initially, but when I called them, they had already called back about completing the work as contracted. They weren't able to finish it the first day, but they did come back and do it right. They insulated, put some windshields up, removed siding, and fixed a vent on the roof that wasn't properly flashed. I think I heard of the company from Best Pick Reports. I would give them an A-.”
“They would be my first choice if I had to do any more exterior work on my home. They were pretty efficient, clear, and organized. They got the work done without me having to be home, which was good. This is the second time I've used them, and they've been able to complete the job without any rework or complaints on my end. They initially replaced some siding on my house and some rotting wood underneath a window. They also replaced the collars around the piping and the roof. Everything is holding up fine. There were no communication problems. I'd give them an A.”
“I had a very positive experience with An Exterior. They did roof and siding work for me.”
“They did some very good work for me. They replaced some siding, some flashing, and some roof shingles after one of the windstorms. They were timely, and it all matches well with what was previously on our house. I'm not exactly sure if they matched the shingles, but I haven't seen that there's anything different hanging up on the roof. The customer service was very good. I didn't have to do any cleaning after they were done. The time frame that it took to do the job was reasonable. I'd say they get an A.”
“We are very pleased with the work that An Exterior has done for us. They have done work for our home and rental property. We've had them do siding, windows, roofing, trim—I think that anything to do with the exterior of the house they've pretty much done for us. They are prompt, clean, and professional. They go out and do whatever needs to be done, take pride in themselves, and stand by their work. I give them an A.”
“They did fine work. They replaced the fascia board with AZEK, replaced the gutter, and rebuilt the doorframe on the side porch. It was done in about three days altogether, I guess—it was in two parts. This was my first occasion to use them. I have a plumbing contractor friend who recommended them. I had a fine experience. I would give them an A.”
“An Exterior repaired some siding, and I would give them an A. I wasn't there when they did the work, but everything was OK.”
“From the get-go, the young lady I was talking to on the phone was very nice. It didn't take much to explain what my problem was—she seemed very knowledgeable about siding. She knew exactly what I was talking about. It was easy to make an appointment with them and get them out. It was my first time using An Exterior, and I would give them an A.”
“This was my first time using An Exterior, and it was a very positive experience. I had some trim and siding come off the top of my house in a windstorm, and they came and did the job. Actually, I never even saw them—I came home, and it was done. Everything still looks good.”
“They did a pretty good job, and the work is holding up fine. I think it was excellent. It should last for two years. The crew that came out was courteous, and everything turned out well.”
“I've had a positive experience using An Exterior. They repaired some dormers, and the quality of their work was tops. It was 103 degrees that day, and the workers that came out were very nice. I would recommend them—A+.”
“They were in Best Pick Reports—we actually pick a lot of things from that book. I wasn't here, but my husband dealt with them, and I remember he was very happy. They repaired damage from the hurricane in the fall. The quality of the work was very good, and they finished the work in a reasonable amount of time—no complaints at all. I would say A+.”
“This was my first time using An Exterior. I got them from Best Pick Reports. They did work for me over the last year or two. They worked very clean and neat, they showed up on time, and they were true to their word. Other companies promised to give me an estimate and never turned up. This was the company who kept their word. They did the PVC wrapping in my house, they put in a sliding door for me, and they fixed the outside of my house. I think I received a warranty. He said I should let him know if there's any problem. Everything worked out OK. I would use them again. I'd rate them an A.”

An Exterior is excellent in everything they do. They are superb. They did roofing, siding, gutters—they did pretty much everything outside my house. I'd give them a twelve out of ten. An A+ grade, definitely.

An Exterior's service was great. I was very impressed with them compared to other people that have come to do work around the house. They did the siding, and they were very prompt when they came. They just do good work and have good workmen. I would give them an A+.

I'd give them an A. I have no problem with their service.

The siding and gutters were all done by An Exterior, and they just did a super job. They did the siding, gutters, and downspouts. They did the roofing, too.

They helped me with siding about a year-and-a-half ago. Everything has been a positive experience. The consistent thing was that they set high expectations, and then they executed the work perfectly. We were looking for a particular composite siding that they provided. I would recommend them.

The workers were definitely very friendly and professional. They did their job. They cleaned up afterwards. I was pleasantly surprised because it was much cleaner than another contractor I’d used.

I had roofing and siding done. My mortgage company has to inspect it—that hasn't happened yet—but I feel confident they did a very good job. They were quick to respond, and it was a job done quickly because of the full crew. They cleaned up and kept their promises. They showed up when they said they would.

They did a great job. They were in Best Pick Reports last year, and that's how we found them.

They're a wonderful company. I give them nothing but A+'s. I've used them for a long time. I'm a real estate agent, and I use them for my real estate needs. They do a wonderful job. They don't give me any problems. They're honest, and they do the work they say they're going to do. They tell you what the offer is, and they do the work, and everything's fine.

An Exterior did the siding on my house. It was in the summer. They were very knowledgeable. I have nothing but good things to say about them. I would use them again and I have recommended them to others.

They're great. This is the second time we've called them. They did some work for us either last year or the year before. I'm the condo manager, and we've got 14 townhouses here. They did some the year before, and then we had them finish up another six or so this year. We like them a lot. They're very prompt, very efficient, and they're in and out of here very quickly. They also seem to use good materials. We had some storm damage from the winter on a couple of gutters. I told them, you know, that I thought I was going to have to wait because there was a lot of repairs in the area. But we could've had them in the next day if we wanted. They're very flexible and very reasonable.

They did some siding work for me quite a while ago. My recollection is that they replaced some gable vents. It was a relatively small amount of work. I would say that I am very satisfied with their work. I would refer them to somebody else and have in the past. What stood out about their service was that it was extremely timely.

It's pretty good. So far we haven't had trouble. I was happy with the work. I think I would use them again. They were a good company.

We had them, and so far it's doing good. No problems. It wasn't really siding replacement they were doing—I had a lot of wood on the exterior of the framing. They replaced that and put up different material because it was rotted out.

I liked them. They are very good. I have used them on a couple of jobs. They also did an exterior siding for me a few years ago. I thought they did a good job. I would recommend them to other people.

They replaced a few siding pieces that came off, and they're also the ones that did the work around my windows. They were fine. I would recommend them to other people.

They did a good job. They replaced the siding and fixed the roof and the gutter. They did all of that. I would use them in the future.

An Exterior put some wood replacements around the windows, except we didn't use wood. We used some composite. They also replaced an exterior door. They did a great job. I would definitely refer them to others.

They do a great job. They were the ones that put HardiePlank on our house. When they came out, they were on time and professional. We were very happy with them. They were very efficient. We were very pleased with them.
