"I had a great experience, from the sales consultant, through to the installation crew. I ordered 26 windows, no two of which were the same size, for my old house. The windows were delivered in literally half the time that other companies were quoting me and the team installed them very soon after. The installation process went very smoothly and the attention to detail finishing the interior pvc trim and the exterior aluminum trim exceeded my expectations. The pricing was competitive for the well specified provia windows. I would have no hesitation in recommending Grand Opening Windows and Doors. Don't fall for the high pressure sales techniques and lower specifications/warranties of some companies when you can work with a company of integrity and quality like Grand Opening Windows and Doors."

"I hired Al to paint and do minor touch up to my fathers house to get it ready for sale. After seeing his great work, I decided that I would hire him to do work at my house. I had him install a new back door and screen door. he installed new lights above my kitchen cabinets, he finished the vinyl floor in my bathroom, he hung a new ceiling fan. He redid the dry wall in my bathroom around my tub. He is very punctual, he is very detailed on making sure everything is right. I also have in on schedule to do a few more jobs. Great job Al and to his helper, go teamwork."

"Scott and company did a fantastic job on a cracked picture window. Their pricing was more than reasonable, over $400 under another local competitor, he did a great job, cleaned the window when he was done, cleaned up the debris, all around great experience. He was incredibly fast also, I think the window came in a week or two after order."

Window Door Contractors FAQs, answered by experts

The most affordable way to screen in a porch is to add a base track system to an existing wooden frame. The whole process should cost around $2,000 for supplies, depending on the size of your porch. It’s much pricier to build a screened-in porch or sunroom from scratch—and you’ll probably need to hire a contractor for a project like that.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.

While the telltale signs can vary for different types of screen doors, it may be time to learn how to install a screen door if you're noticing rotting, warping, or splintering accompanying the sagging. If you’re unsure whether to replace a sagging screen door, consult a local screen door pro for an inspection and final decision.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

A screened-in porch requires maintenance to keep the screens clean and in good shape, and you may have to do some screen repair or replacement from time to time. A screen porch isn’t an all-season porch, so the weather can get in, including wind and rain.
