Customers say: True professional

"I contacted CWE to replace 8 windows and 1 patio door. Jeff came by and did the consultation. He was very friendly and professional. Communication 5/5 - Jeff was very responsive to questions and clearly communicated the work and timeline. Timeliness 5/5 - Both the consultation and installation started on time. The windows actually arrived sooner than expected. Quality 5/5 - The installation team laid down blankets before starting any work. They removed the old windows without damaging the surrounding wall. They installed the new windows and applied the cleanest caulk line I’ve ever seen. They cleaned up after themselves. The Anlin windows that were installed works perfectly and are beautiful."

"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

Window Door Contractors FAQs, answered by experts

Rescreening your porch can take a few hours to a whole day, depending on the size of the enclosure and the amount of screen that needs replacing. If you decide to have a professional handle the rescreening, be sure to get a timeline and a cost estimate so you know how long you’ll be without the screened-in space.

The best type of window screen for your home depends on your region and your family’s needs. While fiberglass window screens are a popular, affordable, and easy-to-find choice, you may be looking for different benefits, such as a more high-end look, increased strength, or extended durability. The best window screen meets the demands of your home and its residents while staying within your budget.

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.

Among the various entry points into your residence, it's crucial to recognize that your basement windows are arguably the most susceptible. Basements usually have windows facing the side and back yards, often concealed from driveway floodlights, porch lighting, and doorbell cameras. Their vulnerability underscores the importance of reinforcing basement window security to safeguard your home from break-ins.

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.
