Michelle Shepperson on KJ Replacement Windows & Doors

Our house in Oakland had original single pane windows from the 1940s that were drafty and impossible to clean. We decided to replace all of them before winter and chose KJ Replacement Windows based on their reviews. They came out and walked us through the different options, explaining the energy ratings and styles without being pushy. Installation took three days for 12 windows and the crew was fantastic. They showed up early, protected our floors and furniture, and cleaned up completely each afternoon. The difference is incredible. The house is so much quieter now and our heating bill dropped noticeably last month. The windows look beautiful too, they matched the craftsman style of our home perfectly. We also had them replace a stubborn sliding door that never worked right. Now it slides smooth and seals tight. Fair pricing and professional work all around. Highly recommend them.

The building being historic,the windows had to under careful technical repairs to refrain the old-world charm. The craftsman worked great even matching the original wood frames.
