"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

Yes, you can replace the screen without removing the door in most cases depending on the frame holding the screen. Doors with removable spline and screen frames make it a snap to replace the mesh while the door remains in place. The best part is that it’s a simple DIY project requiring a few tools in addition to the screen material.

There are different types of screen materials available when purchasing a screen door, but the two main options are fiberglass and aluminum. Fiberglass is lightweight and affordable, but can stretch out, so it needs to be replaced more often. Aluminum has a higher upfront cost, but is more sturdy. Aluminum can be more difficult to install, even if you know how to replace screen door mesh.

Most windows last for 15 to 30 years, depending on the frame material and the glass quality, but most will require repairs during that time. Windows gradually lose efficiency, so it’s usually best to have a window repair technician inspect and service your windows every five to 10 years. You should also repair your windows if you experience the following:

  • Leaks

  • Drafts

  • Difficulty opening or closing

  • Sudden increases in heating and cooling bills

  • Outdoor noise becomes more audible

  • Signs of physical damage

Tears, holes, or difficulty in opening and closing suggest a need for repair.

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.
