Get matched with top window and door contractors in Dearborn, MO

"Our old windows did not stop the heat from the sun, but our replacement windows with argon gas from Window World do stop the heat from the sun. So happy we made the decision to get windows from Window World."

"I am so happy with the work that Cornerstone did on our windows. After dealing with several lengthy, high-pressure sales pitches from other companies, Derrick from Cornerstone was a breath of fresh air. He came out in May and was able to quickly give me multiple options for the best products for my house. I appreciated that he did not try to upsell me, while still showing me high-quality products to choose from. The windows came in early July, but I had to postpone the installation until 7/27, and Cornerstone was so flexible about the schedule. The crew showed up promptly and worked efficiently without cutting corners, they were friendly, and they did a great job cleaning up after. We noticed an immediate difference in the temperature and comfort of our home as soon as they were done. I was also impressed that one of the owners called me the following Monday to make sure we were satisfied. We received stellar customer service, high quality work, and an excellent finished product from Cornerstone. I would highly recommend them for any window replacement project!"

"The installers were courteous and professional. The only problem is one of the windows was delivered defective. The company quickly promised to repair it but so far has not even scheduled a repair. I don't mind if its weeks/months out, but I do want to be on the schedule. Otherwise it seems like once they had our money, they stopped caring."

"Very thankful to have had Chad work on my house as it needed several interior and exterior repairs before I could put it on the market. He worked really hard to get everything done timely and especially impressed with the deck repair that he did. In this case, I did not need a new deck and he was very knowledgeable about what needed to be done. Other companies had quoted me a brand new deck, which was not necessary."

"We hired Dan to install a couple of interior doors and he was very quick and efficient. Also reasonably priced compared to many others. He was friendly and honest, and I would not hesitate to hire him again!"

"Super product and very pleasant service"

"This company has excellent windows, doors, and service. The installers did a fantastic job with installation and clean up. I would highly recommend this company to anyone!"

"Good quality work and very trustworthy!"

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."

"Great. The job was done to my satisfaction and I would hire again in a heartbeat."
