They go the extra mile!

“My wife and I had a great experience working with the team at Permanent. We recently moved into a new house with older basement windows that needed replacement. Darryl quoted our project promptly and accurately. His team came out soon after and did an excellent job with the installation. Our energetic toddler was playing outside during the install and damaged one of the screens. Darryl went the extra mile and made arrangements to have it repaired and back to us the next day!”

They were unbelievable!

“Darryl and his team were unbelievable from start to finish. They came in, helped us to determine solutions for our layout, and then completed windows and doors to perfection. We replaced our front door and Darryl took us through a variety of options until we found the one we loved… His entire process and workmanship is top notch. I highly recommend Permanent Windows and Siding. In the near future my wife and I will be completing a full exterior renovation. Darryl is our guy for all of that work!”
