A.G. Williams was asked to strip and re-varnish my double oak entry doors. The doors had a good amount of ornamental molding and detail work plus a half moon glass panel on each leaf. All of which, over 20 years, had turned grey with the finish peeling and opening up the wood to the weather. The doors were a mess. I had a difficult time finding someone who was willing to undertake the project. A.G. Williams reviewed the project, provided a fair price for the work to be done and a solid plan to do the work over 4-5 days. They provided excellent protection to avoid sanding dust getting in my home. The tech spent 3 full days sanding, with much of the sanding done by hand and when he was done the sanded doors looked better than new! The tech (Gideon) than proceeded to carefully brush on 3 coats of marine varnish over 3 days, pausing for weather & dryness of the preceding coat. When he was done the doors looked spectacular!! In addition to a top notch tech they also provided supervision to oversee the job and check in with me when the job was done. This was my first time using A.G. Williams and I couldn't have asked for a better company and job. When I enter my house through those doors it puts a big smile on my face.

Outstanding, professional, beautiful paint job by Pedro, Marco and Pablo! My new hardwood floors were covered with paper and drop clothes perfectly and the team was sincerely a pleasure to work with. My aging co-op apartment walls and ceiling needed a lot of prep work and the end result is stunning. I’m extremely happy and will use AG Williams for future paint jobs. Quality work is never cheap!
