Seamless Metal Gutters Repair
We are so happy we finally contacted A1 Services who correctly identified our problems! We noticed that when it rained the water above our porch was dripping behind the gutter and through the soffit. We contacted another vendor who didn’t run any water onto the roof, and just said it was an issue with sealing the gutters and gave us an estimate. We knew that it wasn't a gutter leak problem since the water was running behind the gutter and through the soffit, so we contacted A1 Services who specialize in roofing, gutters and siding. They inspected our problem, ran water on the roof and noticed the water coming through the soffit behind the gutters. They correctly dianoised the issue and noted that the leak was coming from the overlapping metal tiles. They also said it appeared that no moisture barrier was installed when the overlapping tiles were installed. Walter was professional, courteous and friendly. Would hire them again in a heartbeat!

When choosing a company for a project as important as the roof of the house, you have to take many things into consideration, not only the price, but also finding that contractor that provides you comfort, security and peace of mind that you are in the best hands. That and more was what I found with A1 Services LLC, Gilson treats you like family and is involved in the work 100% from the beginning to the time of picking up the smallest of debris. Thank you for not letting me down.

I recently hired Walter (again) in October 2023 to do a full siding installation and they did an amazing job!! My old house looks brand new! The workers don't play around, are focused and pay attention to detail. Walter does not leave the job unfinished and takes pride in knowing that you are fully satisfied with the job. Always, very courteous, respectful, professional, honest, understanding, etc. etc. I can go on and on that's how good they are. His team is the best. Will definitely hire him for any future projects.

Walter was very knowledgeable when he explained the various ways we could complete our project. Because of the historical landmark neighborhood we live in, my wife and I had to revise our plans and A1 Services worked with us and the finished product looks great. Would definitely hire them again

A1 was very professional and provided a fair price. They went far beyond the level of service by utilizing all the extra material to fix other items which need maintenance. Thanks.
