"Working with Wasco was a great experience all around, both sales and installation. We intend to use them again in the future to replace additional windows. They were incredibly knowledgable and professional. We would rate them an A++"

"Excellent contractor . Great to work with . B & K replaced the window glass in Five Thermopane windows. The window frames were still good so that is why I chose the glass replacement option. Cost, of course, is then far more reasonable. Our windows now are clear - no fogging anymore."

"We had two windows replaced and they look great. We had old, outdated, drafty windows, and now we have beautiful, secure, functional and high quality windows that have kept in the warmth this winter! The windows that we ended up getting have features that we didn't have before and we love it all - the ability to move the screen up and down, easy tilting options to make cleaning the windows so easy, locking mechanisms, etc. The ordering process was easy, and staff were friendly."

Windows questions, answered by experts

Use a high-quality caulk with silicone around your windows, as it’s waterproof and shrink-proof. Or, you can use a caulk consisting of polyurethane or acrylic if you want to be able to paint over it. Caulk made from silicone is not paintable. Avoid using inexpensive caulk that has a resin or oil base. These caulks will not last long and may shrink and pull away from the window as temperatures go up and down.

There are a few reasons your crank windows might not close. First, determine if your window crank is working properly and opening and closing the window when you turn it. If it’s not, the crank may need replacing, cleaning, or lubricating. Another reason your windows aren’t closing could be dirt and debris in the window hinges or sash. Finally, make sure your window lock operator is set in the unlocked position and isn’t blocking the window from fully closing. If you’re still having trouble closing your window, it may be worth consulting a local window contractor.

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

Arched windows are slightly more expensive than standard rectangular ones, but they only cost $50 to $100 more per window. However, adapting a rectangular wall opening to accept an arched window can add $200 to $400 to your total, making them a more expensive option over sticking with a standard window replacement.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.
