Recent siding installation in Washington DC

Rich Colors Protected by Mastic Solar Defense Technology.

Product: Mastic Ovation Solar Defense Siding
Type: Premium Vinyl
Siding Color: Deep Granite

This home in Washington DC had old wooden T1-11 siding and the owners wanted to install blue siding and to emphasize the enclosed back porch that has natural wood. They were concerned a deep color would fade over time. The solution we provided was to install Mastics Solar Defense siding. This siding is specifically engineered to prevent fading of darker richer colors. They do this by applying a coating over the siding that helps deflect that rays of the sun so the siding panel does not absorb all of the rays thus making the color stay for longer. The owners are very happy with the way this project turns out and it looks like a entirely new home.

Local Review in Washington DC

"We recently used Capitol Improvements for an older home in NE DC. This was a siding replacement that was long overdue and we also had the soffits replaced. We were very impressed by the hard work of the crew who would arrive at 7:30 and work until past 6 pm. They appeared very efficient and worked well together. I would recommend contacting and discussing various options with the company as they answered all our questions."
