"The owner himself came to my home, unaware until the installation occurred that the owner was friendly, knowledgeable and helpful for my small window replacement. Treated me with the utmost courtesy as if it were a large job. He made a promise and fulfilled that delivery on day before Thanksgiving. I would recommend Hyperion for any glass or window job hands down. I tried to tip the service man on the return and He said no thank you it’s our job! That tells me that Hyperion is also a great place to work. Happy employees make happy service calls!"

"Midwest arrived on time and 2 men did the job. It took them about 4 hours to complete the task of removing the old tint, clean the window and area, then apply the new window tint. Of course our windows are larger than normal windows that you see in most houses. Our windows run (73" x 73"), they are considered custom windows, because they run so large. However Midwest did a superior job installing our window tint. They didn't leave any seams in the middle of our window tint. Which is great. Our tint carries a warranty, which we are very happy with. The men who did the installation, applied the window tint to 6 windows and they cleaned up all of they mess. They didn't leave any dirt behind for us to deal with and I was very happy to see that happen. Normally, when someone installs something in your home, any mess they make, they expect the homeowner to clean it up, but that isn't the case with Midwest. Their installers clean up after themselves. Personally, I appreciate it. We will use Midwest in the future and refer them to friends & family. We love the look of the windows with the new tint on them. They really make a big difference when the sun is shinning on them. They really cut down on the amount of UV rays and the extra heat which does not pass through amymore. The window tint helps with our cooling (air conditioning) bills. We know Midwest saved us money and gave us a great price on our new window tint. They did a terrific job and we are very happy with the windows. The installation was easy and we didn't have any problems.

"Brad was one of the best people to do business with: not high-pressure at all, very easy going, professional, good workmanship, patiently answered all our questions, and gave us a reasonable price for our three windows. They were only just installed on Feb. 6, '20, so it may be too soon to evaluate their quality, but they seem to be installed well and look well-made for mid-price windows. Brad's clean-up of the work sites was very thorough, as well. We are very pleased with Brad and All-Type Window and Door LLC and would definitely use them again!"

"I canâ t express how satisfied I am with my windows and sliding door after the superior job completed by St. Louis Window Tinting. To say they are excellent is an understatement! But they are!!! It started with our sales consultant (Kathy), who took the time to explain the differences between products and the value each product would add. She scheduled us for the installation that day. The installation team Ed and Bob, weâ re excellent! They are very professional and knowledgeable. They answered all of my questions. They even took extra care to protect our home and did an amazing job!! Thank you St. Louis Window Tinting everything looks incredible! I HIGHLY RECOMMEND ST. LOUIS WINDOW TINTING!!!!"

"I can’t believe how happy I am to have chosen (and WAITED FOR!) Universal Windows Direct! It took 16 weeks from signing the contract, to getting the patio door and window made at the factory, to scheduling the install. Today was installation day. After seeing the quality of the products I felt the wait was totally worth it. The installer—Mr. C. Robertson—was obviously an expert window installer. He explained everything and installed the door AND second floor window by himself. Yes, he was his own crew and not one issue or problem came up. I will recommend Universal Windows Direct to anyone who needs a quality window, door, or other service from this company. And kudos to UWD for hiring incredibly skilled installation experts—Mr. Robertson turned a “normal” install into a truly outstanding experience. Thank you!"

Windows questions, answered by experts

New homeowners in O'Fallon should start by inspecting window seals for air leaks, especially in older homes common to the area. Upgrading to double-pane or energy-efficient windows can help manage temperature swings. Reinforce window locks for added security, and consider installing storm windows to protect against severe weather. Cleaning window wells and replacing worn weatherstripping are also smart early maintenance steps.

Helpful?

To keep window service projects safe in O'Fallon, install window guards and stops to prevent accidental falls, and opt for cordless window coverings to eliminate cord risks. During work, set up temporary barriers to keep children and pets away from the area. Choose pet-resistant screens for added durability, and discuss safety measures and thorough cleanup with your contractor before starting the project.

Helpful?

For minor window issues in O'Fallon, regularly clean glass and tracks with mild soap, and check for small gaps or worn weatherstripping. Replace damaged caulking to improve insulation and keep out moisture. Always use a sturdy ladder and avoid leaning out windows. If you encounter broken glass, persistent fogging, or structural concerns, stop and contact a professional for safe, effective repairs.

Helpful?

When hiring a window service pro in O'Fallon, prioritize those with proven experience handling local weather extremes—hot, humid summers and chilly winters. Ask about their knowledge of energy-efficient windows and storm-resistant options suited to O'Fallon homes. Verify they carry proper insurance and understand local permit requirements. A strong reputation and clear communication about timelines and cleanup are also essential for a smooth project.

Helpful?

In O'Fallon, rising energy bills, noticeable drafts, or condensation between window panes are strong signs it’s time for service. Watch for ice buildup or water stains around frames during winter, and inspect for rot or sticking windows each spring. If you spot cracked glass, warped frames, or difficulty opening windows, it’s best to schedule professional help promptly to prevent further damage.
