"Let me just say that Bob Morgan Did a excellent and beautiful job on my french patio doors leading to my deck. He actually went above and beyond by knocking out all old rotten wood on both sides and bottom from the rain and replaced it with all new insulation and new wood, new boarders and he went out of his way to replace the knob handles with a beautiful hook latch handle to make the door more decorative,my new doors just make such a beautiful addition to my den.Bob did a fantastic job, And I will be using him again for multiple projects in the near future. And did i mention his prices are very reasonable and fair. And he also cleaned up after the job, and last but not least he was truly very professional, and he was always punctual and would always give you a heads up when he was on his way which was so great, I definitely recommend him without reservation for any wood work or etc.....Linda L"

"EcoView has been absolutely amazing to work with. They gave us an amazing price on the siding and all our windows and doors. We didn't feel pressured to sign a contract like we did with other companies. We were so lucky to work with Anthony, Rob, Steve, Diana and Carlos's crew. Not only did they do an amazing job on our siding but we happened to have another company at our house to give us an estimate on our doors and windows (we didn't know EcoView did doors and windows as well) and we were so lucky that Steve had stopped by to see how the job was coming along. EcoView ended up saving us $10k compared to the other company. Carlos's team did our siding and they did such a great job that we requested his team again for the windows and doors. Rob and Steve were very quick to respond when we would call or text with any questions or concerns. We loved our experience with EcoView so much that we recommended them to a friend within days of getting the work done!"

"The professional (Mitch) tackled a difficult job. These were heavy patio doors, installed over 25 years ago, with damaged and worn tracking. They are now sliding easily and more securely with a new, secure lock. He is now putting a new lock on our front door. He is reliable, efficient and extremely competent."

"John was great. We hired him to replace 3 doors on my ground level to help modernize my home appearance. The job wasn’t as simple as I thought but John reassured me he’d get the job done and that’s what he did. He was on time, clean workmanship and quick turnaround. Definitely will work with John Lang and his partner Joe on future home projects."

Window Door Contractors FAQs, answered by experts

If your door has interchangeable inserts, you’ll likely want to swap the glass out for a screen during the summer months. The process to do so will vary by door, but you’ll follow these general steps: First, use a flathead screwdriver to pop out the retainer strips—the plastic strips running down both long (and sometimes all four) sides of the door. Then gently pull them out by hand. Carefully remove the glass insert from the door and replace it with the screen. Finally, push the plastic retainer strips back into place, working from top to bottom.

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.

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

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

If you’d rather repair your screen door mesh than replace it, you can patch it. Purchase a mesh patch for screen doors with small holes or tears, especially if the mesh is pretty new. Hardware stores and websites sell mesh patches that are easy to apply with an adhesive or a warm hair dryer. Keep in mind that repairs won’t look as aesthetically pleasing in most cases as a full replacement.
