"2nd time I’ve hired Diego to make a custom glass door for a bathtub. His workmanship is excellent and that of a perfectionist. Very clean. Goes over all of the details before doing the project, gives a quote on the price, and then keeps to the timeline to get the job done. No fuss. No mess. Can’t ask for anything more."

"Our church was built in 1958 and has a main window looking out over the property. The window is 25 feet tall and 15 wide. It has 42 panes that were various shapes including rectangles, trapezoids, and triangles. The glass was single ply, mounted in a redwood frame. Over the years some of the panes had cracked, some caulking loosened and the overall appearance and thermal efficiency had degraded. For the last several years we had made attempts to find contractors to replace the glass with double pane windows, but the size and height of the window, plus the need to custom make 42 panes of double pane low E glass in the various shapes and in precision sizing made it next to impossible to find someone to take on the job. Renewit, was the exception. Vincent and Jessie brought in scaffolding to reach the highest panes, took detailed measurements, had 42 new double panes manufactured to spec, and working from a lift, replaced and resealed the entire window. To finish the job, they re-stained the redwood frame work inside and out. Restoring our beautiful window to like new condition. This was a complex job for any contractor to take on. One that most refused to bid on. Not only was the project handled professionally, Vincent and Jessie are great to work with. Without reservation, I would recommend them for any window job no matter how small or how big."

"Fantastic work! They were very responsive throughout the whole process and provided helpful advice regarding our project that enabled us to save money without sacrificing quality or workmanship. The company provided competitive quotes that were budget friendly. We went back on forth on paint color for the deck and front porch and Fernando was very willing to accommodate us. We would highly recommend working with them!"

"We hired Ken to convert a front closet into half closet/half pantry. This required him to create a side entrance into the closet to install multiple custom pantry shelves and install a barn door. He did a fantastic job with the project, was clean, neat and had great communication. He was flexible with issues due to Covid and the lack of power due to Isaias. We couldn't be happier with what he built for us. Great skill and attention to detail. Thanks!!"

Window Door Contractors FAQs, answered by experts

Ensures proper fit and function, maximizing insect protection and airflow.

Professionals ensure repairs not only fix current problems but also prevent future issues, improving efficiency and aesthetics.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

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.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.
