I also requested several quotes for this work to repair my deck - Alan came in at a very reasonable rate. Much more so than some of the other quotes and the work he did was of high standard. See photo of the time he took to sand the edges of the handrails; he also took special care to choose high quality boards. Even when he ended up realizing that there would need to be additional work to be done that would come at an additional cost to me, he made sure to talk me through my options, he made recommendations, and never forced me into anything. Instead, he worked with me to find solutions that would result in a safe, quality deck and also at a cost that I could manage. We're quite pleased with our repaired deck and would absolutely hire him again. He exceeded our expectations.

But a month after they finished, we painted the walls and discovered they used non-paintable caulk everywhere. as we've had time available, we've tried various methods to fix it. Paid all that money and it looks crappy because of the caulk. (Also several places where they installed baseboard and nails weren't all the way through. Speed of install was good. But ended up with a time consuming mess that still doesn't look finished. (Installed around Feb 2026 in Volant, PA)

Tony came the same day (within 30 minutes from our call). He quickly diagnosed the problem and temporarily fixed it until he could return with a part the following day. He finished it the next day when he said he would and cleaned up with his shop vac. Very reasonable. I plan to hire him for some window repair work.

The windows make a huge difference both in terms of letting light in and also insulating the house. I especially like that the windows were custom made and they did a great job with the metal trim.

Came across the company through the home and garden show of Pittsburgh. Was able to schedule an…read moreestimate at our house which went very well. We ordered replacement windows. Scheduling was easy and windows were installed on time and finished early. Installation team was very professional and did an outstanding job. The trouble began at the end of the installation. We were asked to sign a completion certificate, which I completed before the installer left. No indication of any trouble. A week later received a message that they required my spouse's signature on the completion certificate. We were confused because we had signed it. We logged onto a link provided and resigned. Continue to receive notices that they had not received it, but just figured that the system was behind in updating since just a few days passed. Week and a half later received a very rude phone call from the accounting department staff member. This person threatened to turn us over to collections for payment because we didn't sign the form and Andersen's own finance company would not release the funds to Andersen till it was signed, certifying the job was acceptable. As busy professionals and preparing for a family wedding it was exhausting to try to log on and continue to sign a document you've already signed twice. Threatening a collection company on customers with outstanding credit, just a few days after job completion, with a delay due to confusing circumstances and not lack of trying to pay, is unacceptable professional behavior. Why wasn't this identified at the time the completion document was first signed? Again, the installers, the sales person, everyone else was professional. The accounting department person showed no empathy and needs training or other employment.

He sold me keyless entry that was supposed to be a "lifetime guarantee". It was a set from Lowe's that broke a month later. He also sold me a beautiful French door but left the handles mismatched and incorrect from what I picked from the original catalog. He scrambled the day of installation to run back and forth from Lowe's and then blamed the mistake on his contractors. He then acted like the handles were satisfactory when they don't even MATCH! Also did not tell me until the day of installation that I would be responsible for painting the trim and patches left after the installation. I have been chasing him to correct the handles for the past month. This guy is only looking to put money in his pocket and could care less about service or the final product. He even had the nerve to ask me for final payment before the work was complete. Luckily I waited until the door was in but it looks like I will be replacing both the keyless entry and the French door handles on my own. The photos attached are supposed to be the "final product." Scam artist is all I have to say.
