"Excellent work. We purchased natural cherry cabinets in shaker style, with the panels made of solid wood rather than veneer. That is more difficult work, as each panel has to be constructed from several planks. Moreover, the clear finish would leave any flaws more visible. Simply put, the doors are beautiful--flawless in both construction and finish. They are similar in quality to custom cherry furniture we own."

"Tech that arrived was lousy. Came out of truck complaining about a back ache, blamed my AC issues on old windows. Never looked in the attic. Ended up hiring a company out of pocket who did a thorough inspection and made sensible recommendations."

Window Door Contractors questions, answered by experts

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.

Some local utilities or state programs offer rebates or tax incentives for energy-efficient upgrades, including solar screens. Make sure to check with your local energy provider or government agency to see if you qualify for any cost-saving programs. Federal tax credits may also be available for qualifying window and exterior home upgrades.

If you’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.

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.

If you’d rather repair your screen door mesh than replace it, you can patch it. Purchase a mesh patch for screen doors with small holes or tears, especially if the mesh is pretty new. Hardware stores and websites sell mesh patches that are easy to apply with an adhesive or a warm hair dryer. Keep in mind that repairs won’t look as aesthetically pleasing in most cases as a full replacement.
