"Max got the job done! He was quick to communicate and was able to come out even earlier than expected to get started. My situation was a bit more complicated than usual, but Max stayed persistent and found a way to get everything resolved. His pricing was also fair and honest, which I really appreciated. I would absolutely recommend Max and 417 Elite Solutions LLC to friends, family, and anyone looking for a reliable professional who shows up, puts in the work, and gets the job done."

"I would like to give Harris Renovations a very positive recommendation based on the huge amount of work they did to my house. They replaced sticky, laminate flooring with engineered hardwood. They painted the entire interior, replaced light fixtures, and updated old outlets. Craig installed energy efficient windows. Casey built a custom bathroom vanity for me from an antique dresser I bought at a flea market. They really did a fantastic job. Since then, I have hired them to build a deck. And, they are currently building a craftsman-style cottage with a porch that I plan to use for storage."

Window Door Contractors FAQs, answered by experts

Solar screens use a thick mesh of polyester to block out the UV waves and solar heat. While they are more expensive at about $7.50 per square foot, they can protect your porch or hardwood floors from sun damage and keep the room or porch on the other side of the patio cool.

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

If your door has interchangeable inserts, you’ll likely want to swap the glass out for a screen during the summer months. The process to do so will vary by door, but you’ll follow these general steps: First, use a flathead screwdriver to pop out the retainer strips—the plastic strips running down both long (and sometimes all four) sides of the door. Then gently pull them out by hand. Carefully remove the glass insert from the door and replace it with the screen. Finally, push the plastic retainer strips back into place, working from top to bottom.

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.
