New Windows in Portland & Vancouver:
It’s the Right Time!

With the energy-efficiency incentives available now, there has never been a better time to replace those old windows that are letting all the heat out! Take federal tax credits (when they are available), rebates from the window manufacturers, then match those with the energy savings achieved when you purchase 5 or more windows and the case for savings and efficiency has never been better.

Quality is not universal among all brands, so Therm-O-Loc has done the research and testing for you.   If we sell it – it is top notch.  Included among our window brands are Milgard, LBL and Cascade Windows (which is actually manufactured locally).
