"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

There are many ways to customize screens, including customizing frame colors and mesh styles to complement your home’s aesthetic.

A vacuum with a hose attachment or a lint roller can easily remove dust from your window screen. Pressure washing window screens is another option, but you should make sure you have the appropriate nozzle and pressure setting to avoid doing extensive damage to your window.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

Window repairs cost $175 to $615, depending on the type of repair. Because double-hung windows have two sashes and multiple pieces of hardware, like locks and handles, there are many parts that can break over time. Repairing locks, latches, or other hardware costs about $75 to $200 and is easy to DIY. Fixing one or multiple sashes costs about $200 to $600.

Garage door screens can expand your living space, turning a garage into a home office, gym, or entertainment space. They provide comfortable ventilation, insect control, and privacy, allowing you to enjoy your space all year round. Consult a local garage door screen installer to add this feature to your space.
