"I absolutely love the whole processes. Unlike other big names, Mr. Scott didn’t push at all. No sale pitch and other hidden fees. Everything was transparent. When I requested a estimate, he contacted me that evening and stopped by in two days. He spent less than 20 min to measure windows sizes roughly. That was it! He sent me a quote next day and the price was really competitive. We communicated via emails for several questions and he answered them all quickly. He gave me enough time to make the final decision. Like I mentioned earlier, no pressure. Once I made the decision and signed contract, the actual contractor came by to measure everything accurately. After waiting several months (it took longer than I expected because of the pandemic), windows and sliding door finally arrived and set up the installation date. The installation contractor, Mr. Park’s team, is absolutely great. They were professional and their workmanship is beyond expectation. Several occasions, his team confronted some issues and they explained them clearly and found ways to get jobs done, In less than two days, 11 windows and 1 sliding door were finally installed. They all look beautiful and I am more than satisfied, I will absolutely hire them again for any future projects!"

"We have had NovaExteriors replace all our gutters, windows, sliding doors and front door over the last several years from the contractor grade products that the town house was built with. We have been very pleased with everything. They installed our steel front door about 10 years ago and we started to have issues with the deadbolt not aligning with the door jam and the rubber sweep wearing out over time. I contacted NovaExteriors, made my appointment and they arrived right on time and performed the needed maintenance that was required. The door is back to being perfect. Once again, we were very pleased with NovaExteriors, their prompt arrival and the quality of work. You can't go wrong with NovaExteriors."

"A wonderful experience all around! We had 15 windows and a sliding glass door replaced. Our Salesperson, Harlan, was very professional and explained the benefits of the new windows and all about Power as a company. The installers arrived on time and completed the entire job in a day! Everything was installed perfectly and the crew was courteous and cleaned up after themselves. Erin came to visit the next day to make sure everything was up to their standards and addressed any questions we had. Most certainly the best experience we've ever had with a home contractor. Highly Recommend!"

"Josh came over quickly, measured, took pictures, and gave me a quote within my existing budget. Ronnie and Brock removed my old cooktop and under counter vent and replace them with new units. They were able to effectively deal with some minor issues and I was very pleased with their friendliness and professionalism. I would highly recommend them for any home improvement work."

Window Door Contractors FAQs, answered by experts

Solar screens use a thick mesh of polyester to block out the UV waves and solar heat. While they are more expensive at about $7.50 per square foot, they can protect your porch or hardwood floors from sun damage and keep the room or porch on the other side of the patio cool.

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.

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

Options include fiberglass, aluminum, and pet-resistant screens to suit different needs.

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.
