"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"We had them clean the inside/outside/screens and sills, it was night and day how much better we could see afterwards. I didn't realize how dirty all of our windows were. The used just water on the windows too, I was shocked that no streaks were present afterwards. I will be looking to do this more often in the future and would not hesitate to use Virginia Window Cleaners again."

"I received quotes ranging from 5k to 800.00. This company was the only one who told me that my windows might be under warranty, and they tried to save me money. With honesty like that, you can tell they hire staff with integrity. I would gladly recommend them and work with them again for any future window repair needs."

"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"I had new glass installed in a patio door, a three window bay with floor to ceiling glass, and a front window. All were custom wood windows that were old. Metro did an outstanding job. They had a competitive quote. They were professional and friendly. They cleaned up after the work. My wife was happy. All good. High recommend."

"Wonderful to work with. Very honest and willing to work with you within budget. We had several windows that were chipped by the home builder. Jeremy was happy to complete the job at a later time when we could get the windows replaced. Flexible, honest, and very pleasant to work with. I wish all contractors were as outstanding as Jeremy!!!!"

Windows FAQs, answered by experts

Most homeowners prefer to service their windows during the spring or fall when temperatures are the most bearable, and having large openings in your wall won’t drastically increase your heating and cooling bills. However, while these seasons are the most convenient, you’ll also tend to pay more for window repair due to the increased demand. If you want to reduce labor costs, consider making window repairs in the off-seasons. Avoid waiting until the heart of winter to do repairs, though, as you could run into leaks and heat loss issues.

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

Whether you need a permit to install a bay window depends on the project's scope. Replacing an existing bay window typically does not require a permit. However, if you are adding a new bay window, requirements can vary. Adding a new bay window to the front of your house usually requires a building permit, while adding one to the side or back of your house often does not. It's always best to check with your local municipality to confirm the specific requirements in your area. Additionally, if you live in a historic district, you should consult your neighborhood association to ensure your project complies with their construction guidelines. If you're unsure about the process, a professional can provide guidance.

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.
