"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

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

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.

If you’re not an experienced DIYer, consider hiring a local patio repair contractor to rescreen your porch or sunroom. Unless you’re only repairing a small rip or hole, this project is not an easy job. A professional can also make recommendations for materials that will work best for your porch.

Yes, if you have ventilated skylights, you can install insect screens on them. Insect screens for skylights cost $10 to $50 each, depending on their size and quality. Most pros highly recommend insect screens for ventilated skylights because they keep pests outside of your home while allowing fresh air inside.

A garage door screen can be a worthwhile investment, especially if you frequently use your garage for activities like a home gym, workshop, or other hobbies. It allows you to enjoy fresh air and natural light without worrying about bugs. Additionally, a screen provides ventilation that can improve air quality when you're working with paints, varnishes, or producing sawdust.

The best option depends on your usage. For occasional use, a DIY fabric screen is a low-cost, simple solution that you can put up and take down as needed. If you plan to spend a lot of time in the space, investing in a customized, professionally installed garage door screen can help transform the area into a new hub for your household.
