"Paul and his team were great. We replaced most of our windows as well as an old wooden window. We were concerned that the replacement for the wooden window wouldn’t come out as nicely but the replacement was beautiful! We are looking forward to our electric bill this summer."

"
- I am so happy that I decided to go with Fox Creek Builders to install my window and 2 sliding glass doors. From order to install the process was excellent + only took about 3 weeks. Amazing since it took another vendor a month to tell me they could not fill the order I previously requested. Max, the owner, came out with Fred to measure and discuss my request. When Fred installed the custom doors + window they fit better than the original doors they replaced---fit like a glove. Fred was extremely pleasant, neat + a precision installer. They removed all the old debris, vacuumed all the rooms, deck + cleaned all the windows after install. I did not even have to remove my blinds during the process + they were particular about routing my outside cable wire.
The doors are very high quality argon + insulated glass. My husband + I just love how smoothly both the doors + screens move along with the other bells+ whistles. Even my dog loves the doors + the crew. Max came out and inspected the job + again explained the features so we did not miss anything. We couldn't be more pleased with this purchase--well worth the money + I just wish I had done this sooner. Thanks to the Fox Creek Builders--Great team and Great work.

"I recently had my windows replaced and I?m really happy with how everything turned out. The process was straightforward and everything was explained clearly without it feeling like a sales pitch. Installation went smoothly. The crew showed up on time, worked efficiently, and cleaned everything up before leaving. The biggest thing I?ve noticed is how much more comfortable the house feels. There are no more drafts and everything feels tighter and quieter. The windows also made a noticeable difference in how the house looks from both inside and out. Overall a really good experience."
