"We had several windows and doors replaced and I was really impressed with the new windows and doors as well as the professional installation by Perry and his crew. They made sure everything was square, clean, and caulked. Great job! I highly recommend Metropolitan High Performance Windows."

"Al and his assistant installed two window air conditioning units in windows that another installer said could not be done. The other installer from TaskR installed one of the units in a non-preferred window and left quite a mess, including crooked drill holes in my wooded sills. (My place is 105 years old, but my window sills have metal frames and modern windows.) Al and his assistant’s work was perfection! I was so pleased, I have already referred Al to 2 neighbors. Al is great at communication, very pleasant to work with, and honest. They cleaned up everything and offered to take the boxes and packing materials out to my bins. This was a relatively small job, but worth the money. Al charges a 2-hour minimum, which is more than fair. I will hire Al again and continuing recommending him and his team."

"We have an old house with doors that do not work properly but. We did not want to replace the entire front door, but needed it to open and close, latch and lock. Trevor and his partner were professional and respectful and put some work in to getting the door functioning. We hope to be able to replace the doors at some point in the future. and Infinity Locks and Doors will be our preferred contractor."

"Requested a quote, they arrived on time and had sample windows to actually look at. Went with them, they took less than half a day, arrived on time, and the windows look great. For one of the windows, a little bit of stucco was damaged during installation and they notified us the damaged happened, came back, and repaired it the next week. The windows look great and had the best specs out of the 4 other window installers I got quotes from."

"On a home built in 1957 Approved Contractor Inc (ACI) installed new construction windows and sliding glass doors, stripped the house of old siding, removed old plywood sheathing and old insulation, and then insulated and stuccoed the house. What was important was not only finding a reputable construction company, but also one that would coordinate the total project. The added benefits were quality work and high-end material, at a competitive price. Of note, was the stucco method (4 layers-coats - scratch, brown, finish and texture). The texture coat is an elastomeric paint (color of my choosing) that is water repellent, reflective and provides an even color on the walls - with a lifetime warranty. Other stucco contractors stop on the finish coat, with the color in stucco. In addition ACI uses its own subcontractors. ACI was professional, flexible, and did really great work. ACI was a superb choice."

Window Door Contractors FAQs, answered by experts

Yes, a variety of screen materials cut out glare from the sun. Solar screen material can block up to 90% of the glare and heat from the sun, saving on cooling costs. It also offers privacy yet unlimited outward visibility. The cost depends on the size of the screen roll, but solar screens cost between $25 and $90 per roll.

Typically every 10-15 years or whenever they show signs of wear and tear.

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.

The best type of window screen for your home depends on your region and your family’s needs. While fiberglass window screens are a popular, affordable, and easy-to-find choice, you may be looking for different benefits, such as a more high-end look, increased strength, or extended durability. The best window screen meets the demands of your home and its residents while staying within your budget.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.
