"They did a good job especially considering how brittle my old siding had become over the years. I’m pleased with their work and the price was right. I plan to hire them to do a couple more small jobs that I’m to old to do myself."

Window Door Contractors FAQs, answered by experts

Screen doors have a positive ROI because of their safety features. They add protection from debris, critters, and, depending on the material, even heat. However, storm doors are better than screen doors when it comes to overall protection.

A vacuum with a hose attachment or a lint roller can easily remove dust from your window screen. Pressure washing window screens is another option, but you should make sure you have the appropriate nozzle and pressure setting to avoid doing extensive damage to your window.

Options include fiberglass, aluminum, and pet-resistant screens to suit different needs.

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.

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence.
