Greg and his team were incredible. The windows were installed in less than one day and the entire team was extremely polite and courteous. We also had Greg install new siding and gutters installed and we are extremely happy with the end result! We would hire them again in a heartbeat.

Did a thorough job, quick and cleaned up after themselves. Greg even repaired a few places of siding on the front of the house at no extra charge. The siding looks great. I would easily hire them again. Nice work! Great Job!

5 star experience. I'd rate Gmart higher if I could! I don't write reviews, but this experience was as good as it gets. Our house is 40 years old and the exterior started to show signs of wear. Greg and his crew did a great job replacing our siding, fascia, soffit, window trim, gutters, downspouts, and gutter guards. We were lucky enough for our insurance to foot most of the bill due to hail damage, and Greg was wonderful at assisting us through this process, even helping us push our insurance company to approve more than their original estimate. We took this opportunity to not only replace what we had, but make upgrades (cedar porch ceiling, new front and back doors, and upgraded light fixtures) and transform the look and feel of our home. We interviewed 5 exterior companies for the job: 2 were focused on simply replacing what we had and I could tell they were not used to making upgrades, 2 were focused on making upgrades to exteriors (which was nice) but their quotes reflected this, but Greg at Gmart offered a great combination of getting the replacement job done right while offering design ideas/opinions to make our house look great, help us get the best bang for our buck, and avoid poor choices.......all at a great price. While working on the exterior, Greg and his crew pointed out ALL areas where our exterior wood was rotten, needed to be fixed (we had a 5 foot hole in the side of our house where mice were getting in, we had 2 areas of fascia that rotted which caused our gutters to sag, we needed insulation added to a section of our back wall, etc.). Getting those areas fixed offers me a piece of mind I did not expect to get out of this project - bonus! Greg's 2-3 man crew got the work done on time, and even accommodated a few changes (some for free, others for a cost we agreed to before-hand). They arrived in the morning and often were working until 6 - 6:30 at night, cleaning up each night. The crew worked on my house as if it was their own. They were respectful to us, our kids, and our home, and were great to work with. Greg visited the site daily, and talked us through the work performed that day, and the work to be done in the next few days (making sure we were able to give feedback when a decision needed to be made). At the end of the day, we're pinching ourselves. We love how our house turned out, not only because it looks great, but we know the house is set to last another 40 years, and it was all done at a reasonable price. Thanks Greg.

G-Mart was impressive to say the least. Let’s start with the estimate which was one my favorite parts of the whole process. I contacted about six different companies for an estimate which only four responded to. G-Mart owner Greg Martyniak came by and met with me to provide an estimate. I had three other estimates; two of which required that my wife be present for the estimate (which was a sneaky sales tactic to get us to buy on the spot). The other three estimates were all gimmicky and sales oriented. With the other estimates I felt like I was being fed a sales pitch that was long and dragged out. Greg’s estimate was right to the point and efficient. His estimate took less than 30 minutes while all the other estimates each took over an hour. He walked around the house with me and explained all the things that they would do and problems that he noticed that would be fixed by his team. And this was not some drawn out sales pitch, it was efficient and right to the point which I really enjoyed. Greg didn’t use gimmicky sales tactics to push his services on me; he just presented what his team would do, he answered my questions, and then we both went on with our days and he sent an estimate over via email the next day. The price was also very competitive. He was not the cheapest but he was way cheaper than the most expensive estimate I got. One of the things that really caught my eye initially too was not the positive reviews but the lack of negative reviews which was really impressive in my opinion. In reference to the work performed. The crews were very polite and were always working very hard. You could tell they had a great deal of experience in their field. They were very neat and thorough and did everything that they said they were going to do. They found some rotted wood behind the old siding so they showed me the problem and replaced it without charging me extra. I will definitely be recommending this company in the future; our home looks amazing, thank you Greg.

Gmart repaired the vinyl siding on my home in less than 24 hours following my request. I plan to use this contractor for future home repairs. His level of professionalism was superb!
