Real, Local Reviews From Happy Customers


We are very pleased with our 12 new windows. The whole process was easy, honest, and professional. Our salesperson (Keith) was awesome along with any and all employees of the company. I have to give a huge thank you to Edwin and crew who actually took the 71 year old windows out and replaced with the new ones. Edwin and crew were very professional, worked every minute while they were here. We have hired a few different contractors updating our new home. I give Keith, Window Source, Edwin and Crew a perfect review due to they earned it. Thank you and you can trust Window Source with the utmost confidence that they will do just as good of a job for you as they did for us.

After getting quotes from Home Depot and Lowes we decided to call the Window Source of Houston. They quickly scheduled a free estimate. Our salesman, Keith showed up on time and was very friendly & knowledgeable. He wasn't pushy which was an added bonus. We decided to go with the Window Source because the price/time was half of what their competitors were. I was originally told my windows would be 12 weeks out - to my surprise my 12 windows came in 4 weeks! Christian and Nelson came out on to install today. They were on time and did an excellent job. Very fast and efficient. I'm very pleased. If you're looking for new windows this is the place to go!

After getting multiple bids and reading reviews it was hands down Window Source of Houston to replace my windows. Windows came the week I was told, installers came at the time given me and 18 windows replaced in 4 hours! They did an excellent job of protecting my house and furnishings and had someone cleaning up behind each window installed. The furniture was even dusted!! The windows were cleaned after installation. I am very pleased and I would highly recommend Window Sources of Houston.

Jeanell Green

Window Source was amazing. We had all but 2 windows replaced. We also had 3 windows made into one big picture window. When I called to get an estimate, they came out within a day or two. Initially we were going to call a couple of companies out for estimates but ended up going with Window Source right a way. The estimate was reasonable and came out lower than what both my husband and I had in our mind. It took a little about 8 weeks for the windows to come in for installation. The crew was on time, very professional, cleaned and vacuumed all debris. I cant say enough about the quality of the windows and workmanship. Thank you Window Source of Houston, I can see out clearly now.
