One Google customer clocked a garage and breezeway roof by the minute: a six-man crew at the door by 7:25am, work started by 7:30am, and the roof completed by 11am. That customer says Dave came right out with an affordable estimate and no money up front, and that the house stayed dry through a heavy rain with wind shortly after. Wallace Home Improvement does roofing and siding, and its website lists Gray, Scarborough, Cape Elizabeth, Freeport, Brunswick, Windham, Gorham, Standish, Cumberland and Kennebunk as its service area. A recent Google customer had a new asphalt shingle roof, new siding, new gutters and exterior trim upgrades, and says Dave and JP communicated well before and during construction, with both crews cleaning up nails and debris. A recent Google customer had a total roof installation on the house and garage done in one day, with sheeting and tarps laid to keep roof waste off the lawn. A recent Google customer says Dave and his team re-sided the whole house, including new window trim, and replaced some railing. A 2021 HomeAdvisor customer said the scope of the work was explained in detail and followed up with a written contract, and the roofing was completed in one day. A 2021 HomeAdvisor customer said they had used Wallace Home Improvement on over 7 roofs. A 2020 HomeAdvisor customer said the final bill matched the estimate within the contract's parameters and the job was done in less time than estimated. A 2025 HomeAdvisor customer said the job was completed in a day within the agreed time frame, which was needed for insurance purposes, and billed within the quoted amount.
Dave and his team re-sided our whole house including new window trim, and we could not be happier or recommend his team enough. They did a fantastic job. Highly recommend for any outdoor work! They also replaced some of our railing and did a great job fixing that on the fly. Thanks again
We just had a total roof installation completed on our house and the garage. Wallace Home Improvement did an outstanding job! They were so quick to get back to us and they came right out to look at the roof. The work was done in one day! The workers were so quick! They installed the sheeting/tarps to keep the roof waste to a minimum on the lawn. They picked up everything. No piece of anything was left behind. We have recommended Wallace Home Improvement to others.
We contracted with Wallace Home Improvement to install a new asphalt shingle roof, new siding, new gutters and exterior trim upgrades. Dave, JP and other Wallace staff were knowledgeable, professional and communicated well with us before and during construction. The roofing and siding crews worked long, steady hours to complete the work to our total satisfaction. Both crews were very thorough in cleaning up nails and other construction debris before they left. I highly recommend Wallace Home Improvement to anyone needing work done on their home.
I contacted Wallace Roofing and siding about placing a new roof on my garage and breezeway. I have to say that I was impressed. My experience with contractors has been less than optimal in the past. Dave renewed my faith. He came right out in a timely fashion and presented me with an affordable estimate, and no money up front. This is where others have let me down, an estimate given and then never heard from again. Not Wallace, within 2weeks my shingles were sitting in my yard by week three, his 6 man crew was at my door by 725am. By 730am work was started. By 11am the roof was completed, every scrap was cleaned up not one nail left behind. By 1107am it was like nothing ever happened. Except I have a beautiful new roof. Now you might wonder, did they rush, cut corners, is it going to leak because they hurried. Nope, we had a heavy rain with wind shortly after completion and we are bone dry snug as a bug. Thank you Dave and crew, you are now in my permanent file for home repair needs. I will recommend your team to anyone who ask me.
Great experience from start to finish with a team of hardworking, professional people. The roof looks fantastic, and the cleanup afterward was exceptional—you’d never know they had been there. It was truly a pleasure working with Wallace Home Improvement. I highly recommend them!
