Save money, be comfortable

Homes that are leaky use 20-50% more energy to heat and cool the home.

In the Portland, Eugene, Vancouver and Salem, Oregon & Washington areas, any home over 10 years old is almost certain to be under-insulated, with most homes having no insulation at all under the house! Houses that are under-insulated are missing a very simple but essential part of the energy-efficiency formula. Properly insulating your walls, floors, and attic with spray foam insulation, acoustical sound insulation or even foam board insulation not only keeps you comfortable throughout the year and reduces noise from outside, but it is also proven to save energy while reducing your heating and cooling costs. You can trust the Knez team to provide you with the best and most honest insulation solutions. We use only the best insulation products to help you not only save energy, but make your house quieter by soundproofing a room in Portland or prevent drafts in a room in Vancouver with boom in insulation. We know we can help, so call for a free insulation evaluation today!

Cash incentives and tax credits are available!

Being comfortable has never been more affordable.

We’ll help with the paperwork while you enjoy getting 30% off your energy costs! Energy Trust and other utilities offer cash incentives for weatherizing your home and financing for your home improvements. As a trade ally contractor of Energy Trust of Oregon, we can help with cash incentives and state energy tax credits to improve the energy efficiency of your home with more green insulation.

Why Knez?

Northwest owned and operated.

At Knez Building Materials Co., we tend to have somewhat of an old-school mentality, and maybe that’s what sets us apart. We help each other out. We believe in doing the best that you can for the people you work with. From the very beginning, we have been a local, family-run business for the Portland, Eugene, Vancouver & Salem areas, and we’ve stayed true to our roots. We believe in honest hard work, and we believe that our customers deserve the best possible service that we can give them. We’ve been around a long time, and our core values in excellent service and hard work have never wavered. Although we’ve grown substantially since John Knez Sr. bought the company, we still think of ourselves as “the little guys.” Instead of expanding out across the country, we believe that we can better serve our customers by concentrating our efforts right here in the Pacific Northwest. Aside from Portland, Oregon you can now visit us in Clackamas, Eugene, Salem, Tigard, and Vancouver, Washington.
