"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!"

"Spectacular! In the driving snow Jeremiah replaced 2-8x11 window panes, one behind a large storm window that need to be removed, for installation. Been staring at the broken glass for years trying to figure out how it came apart, one look and Jeremiah knew it had to be done from the outside...and that is why I hired a pro."

"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"UNICORP recently replaced 29 windows, including 1 casement and 1 large sliding glass door at our residence. To say that were are pleased with the final product is a great understatement. The company owner, Brian, made the initial visit to our home and he is very personable, professional, highly knowledgeable and very passionate about the product he sells. The installation crew, led by Paul, was outstanding. They were highly skilled, attentive to the smallest detail, very easy to have in our home, AND did a great final cleanup. No trash or debris anywhere. The actual windows are amazing. High-quality, custom made, and reasonably priced. Particularly noteworthy is the significant reduction of outside noise. The screens are barely noticeable which makes for a big visual improvement. For higher cost projects we routinely obtain 3 estimates before moving forward. In this instance, we followed our gut, and went with the first company, Unicorp, cancelled appointments with 2 other companies. Not our usual approach, but our intuition served us well. If you're in the market for new windows you owe it to yourself to contact UNICORP and give them an opportunity to submit an estimate. I'm betting you won't regret it. David and Lauren"

"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs to have a window fixed or replaced."

"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."

Window Door Contractors FAQs, answered by experts

The cost ultimately depends on size, but roughly, the most popular screen materials will set you back anywhere from around $0.25 to over $25 per square foot. Fiberglass and aluminum are usually less expensive at around $0.25 to $0.70 per square foot. Solar screens cost about $7.50 to $15 per square foot, while security screens range from around $10 to $25 per square foot.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

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.

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 solar screens last 10 to 15 years, depending on the material quality, exposure to weather, and the level of maintenance. High-quality materials and regular cleaning can extend their lifespan, while harsh climates or neglect may shorten it. Routine cleaning, inspecting for damage, and avoiding harsh cleaners can help extend the lifespan of your screens.
