Rave Reviews

We know we do great work, so rather than take our word for it, here’s what some of our customers had to say...

“I really want to thank you guys (and anybody else who had a hand in the decision to install the interior storm windows). The level of noise is radically lowered. My office is REALLY quiet now. The difference is remarkable.  A very worthwhile and successful investment in our offices.”

J. Thomas Richardson, Attorney 

“They love it! They are warmer, drafts are down. Everybody’s been happy with how quiet it’s been. 100% agreement, everybody happy.”

Chris Ulrich, Chief Engineer at Samis Land Company

“The other systems simply weren’t competitive. And this is by far the best that we’d seen.  We have glass in this building that’s 120 years old. You don’t want to replace that. It’s charming, it’s beautiful, it looks like a rippling brook in some places.”

–Shawn Jezerinac, Property Manager at the Pioneer Building, Seattle, WA
