Specialty Shaped Window Finishes

Our low-maintenance interior and exterior finishes resist fading, peeling, and chalking even under the most extreme coastal conditions. Finish options include five colored finishes and five wood grain finishes that will bring beauty and natural warmth to your home. 

Our Bronze, Black, Bronze, and Stone White Kynar finishes are AAMA 2605 certified. AAMA 2605 is the American Architectural Manufacturer's Association's high-performance exterior specification. Finishes meeting this certification exhibit outstanding resistance to humidity, color change, chalk, gloss loss, and chemicals.

We were in need of window and door upgrades. SIW did an exceptional job at a reasonable price. Management and staff were outstanding. I highly recommend this company. Thank you for your excellent service!

Viviana C.

We had 24 windows, four sliders, and two doors all installed at the same time. Flawless, and as smooth as could be. The quality of the windows and doors is great. Cannot say enough positive things about the entire experience, from start to finish.
