"I first gave Southern Grace an "A" grade, but since then I have developed a leak, and have tried contacting them by email, phone, and text probably 20 times, and they have not gotten back to me.  Obviously once they are paid, they want nothing further to do with you!

"They've done good work. The quality is really good. Once they started the work it was done quickly, about two days. Rock solid and perfect clean up. Good technicians. They know exactly what they are doing. They give you a discount if you put a sign in your yard, the contract is put a sign up for a week a few times a year. They seemed to forgot to come get the sign a few times.

Window Door Contractors FAQs, answered by experts

It’s possible to make minor screen repairs yourself using a waterproof adhesive for small tears or a screen patch kit for larger tears and holes. However, it’s usually a better option to call in a professional window technician. It’s very easy to use too much waterproof glue, resulting in a messy appearance that might demand a full replacement anyway. A screen repair technician will not only be able to carry out clean repairs and patches that aren’t obvious, but they can also let you know if replacing your screen is a more cost-effective option.

Adding a window to a brick house costs $3,100 to $10,575. Because you’ll need to make changes to the structure of the home, the cost will include obtaining permits and hiring the best pros for this complex job. Larger windows will cost more to install, and the cost can vary based on the window frame material you choose.

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.

For most common repairs, a professional window repair service can fix a window in one to three hours. However, replacing window frames or repairing a large, multi-pane window will likely take longer to complete. For comparison, a window installation or repair professional should be able to replace up to 15 windows per day.

Most window screens last for about 10 to 12 years, assuming they are made from quality materials and receive proper care. The lifespan of common materials like fiberglass and aluminum can vary based on weather exposure, as constant sun or harsh winters can accelerate wear and tear. Regular cleaning and basic maintenance can help extend their life. Signs that a screen needs to be replaced include rips, tears, brittle or sagging material, fading, or a bent frame. While small tears can often be repaired, larger areas of damage typically mean it's time to replace the entire screen.
