Getting three siding quotes in Mercer Island, WA produced three wildly different numbers with no explanation for the variation. Squared Siding's estimator spent over an hour on my exterior and handed me a four-page itemized quote that explained every cost before he left the driveway. The total matched the invoice exactly. That alone made this the most professional contractor experience I have had in years. The siding looks excellent and has held up through a full year of Mercer Island, WA weather since installation.
I wanted vertical board-and-batten siding on a home that was originally clad in aluminum horizontal panels. The conversion requires specific framing details at corners and window surrounds that most contractors do not think through in advance. Squared Siding sent a specialty crew foreman to the initial consultation who mapped the entire installation on paper before the crew mobilized. The result is exactly what I was imagining and the workmanship at every detail point is excellent.
The crew treated the job site like it was their own yard. Debris contained every day, cleanup done before leaving, and a magnet sweep around the perimeter before they packed up on the last day. That level of respect for the property is something I noticed because I was not expecting it after previous contractor experiences in Mercer Island, WA. The siding itself is beautiful and the workmanship at every corner and trim joint is tight and clean.
I called five siding companies in Mercer Island, WA. Two never called back. One gave me a quote over the phone without seeing the house. Squared Siding came out, spent real time on the inspection, gave me a written quote that day, and was the only one that mentioned the flashing issue at my dormer that was causing the recurring leak I had been dealing with. They fixed the root cause and the siding. Worth every penny.
