"This is my second window job with MHP. First time, we upgraded a dozen windows in our home with a high-end product. Everything went perfectly. When I needed replacements in my rental I was looking for value. MHP beat the price of 2 other bids with a better product. Paul and Cathy are true professionals from the first contact to job completion."

"Pedro was very professional, friendly and thorough. He not only repaired and replaced our damaged window trim, he also repainted and checked the seals on all of the other windows. The price was reasonable. I will definitely contact him again for any future work."

"Outstanding work. Will and Bobby did a great job on our glass sliding door. Very reasonable price and theyve cleaned up the job site after work is done. My husband had the issues on the sliding door for many years, been asking him why he wont have it fixed he said he cant find anyone who has good reviews etc. So luckily we found Empire Sliding door Moreno valley. TY."

"Morgan called in advance of appointment to inform us that he was on his way. He removed the sliding glass door and screen and replaced, lubed and adjusted the door hardware for proper closure. Door work fantastic (like new) again. Great service for the cost and would highly recommend him for any door, window and doggy door installation or repair."

Window Door Contractors FAQs, answered by experts

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.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

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.

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.

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.
