"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."

"This is our second window installation with Renewal By Anderson. We had an outstanding experience our first time around, and today our much anticipated installation of two very large stationary windows took place. Bebe and Ryan were our installers for this job. They were awesome!! They were friendly, they were prompt, and they even helped me figure out how to contact Anderson about a window screen that has been damaged by my landscapers. I very much appreciated their professionalism and their extra attention to detail. I highly recommend Renewal by Anderson for replacement windows. Thanks Bebe and Ryan, you guys are the best!!!"

We were interested in obtaining a company to clean our floor vents and one wall vent since we've NEVER had them cleaned since we moved to the Talmadge area 25 years ago.  My intention was to contact at least 2 companies for quotes.  After checking Angie's list for Coit and ASI which had  'B' ratings, I decided I wanted a company with an 'A' rating. What attracted me to G&G was . . . 1) They had an 'A' rating . . 2) They had a special for $199.00 . . . and the 'comments' on services rendered were VERY favorable.  My intention was to ask about the process and then contact another company to compare information.  However, I was so impressed with the gentlemen answering my questions on the phone, I decided to schedule the vent cleaning with G&G.  Scheduled services was set up for 10/7 BUT (to my good fortune) the gentleman called me back within 20 minutes to say that he had a cancellation and if I wanted to have the service performed today, it was now available.  I agreed.  Gabriel and his assistant arrived at my door 45 minutes later.  They were personable, professional, knowledgeable and explained the process as they went along.  I opted to have 'sanitation of the vents' done as well which was another $150.  I don't think I mentioned that at the time I called for the service, the special for vent cleaning had expired 2 days ago.  However, G&G honored the 'special rate' of $199.00.  Wow.

I was thoroughly pleased with the services I received and I would most definitely recommend this company to my friends, family and anyone else that would listen.

"I had a window that was leaking and did not know who to go to for fixing this issue. I found Level Up Contracting through Angi's list. They came and surveyed the problem area. The problem lied behind the drywall and Al told me what work was needed to investigate the issue and repair it. He walked me through the process and quoted me a fair cost for the job. Throughout the repair work he provided updates and what materials he needed to completed the work. Al provided excellent customer service and was very pleasant to talk to. I am very satisfied with his work and craftmanship."

"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."

"Gabriel and his partner were on time, super courteous, and very informative. They showed us how the window locks and built-in stops work and how easily the windows dissemble to clean. This was an excellent experience overall and I would hire Brothers again! The windows are gorgeous!!"

"We were very very pleased with Approved Contractor and would recommend them to everyone. They showed up as scheduled, ready to work and completed the job in a timely manner. They also cleaned up after themselves which was appreciated! Not only Mr. Charney, the general contractor, but also his workers communicated with us regularly and kept us up to date with how the job was progressing. Our satisfaction was very important to them. The windows are wonderful and we definitely noticed our house being cooler and the sliding glass door is awesome! The stucco and roof make such a wonderful difference in the appearance of our home."

"The contractors did an excellent job in repairing the sliding glass door. They were very professional as expected. They assessed the issue as deteriorated rollers. Removed the door, replaced the rollers assemblies, adjusted and aligned the rollers to ensure the correct alignment of the door height was parallel with the frame. The door opens and closes with ease. Could not expected more from those professionals. I would hire them again for any door issues."

Window Door Contractors FAQs, answered by experts

Yes, you can add a screen door to most door frames. The screen should be able to fit standard-size door frames, so unless you have an unusually sized door, you shouldn’t have an issue. Just make sure to properly measure the frame. When in doubt, it’s best to let a pro take care of this task for you so it’s installed correctly.

The most affordable way to screen in a porch is to add a base track system to an existing wooden frame. The whole process should cost around $2,000 for supplies, depending on the size of your porch. It’s much pricier to build a screened-in porch or sunroom from scratch—and you’ll probably need to hire a contractor for a project like that.

Many windows carry warranties from the manufacturer or installer that may cover the cost of repairs for a fixed amount of time. When installing or replacing windows, ask about any applicable warranties, what kinds of damage and repair they may cover, and what the procedure is for making a warranty claim.

Yes, adding windows adds value to a brick house. Homeowners don’t shy away from more natural light and an opportunity to get fresh air. Adding a window is particularly beneficial if you live in an area with good weather for much of the year or if your home has a nice view. Keep in mind that many older brick homes have historic wood windows that add to the charm of the house. When you install a new window in a brick house, you’ll want to find one that matches the aesthetic of the existing windows.

While windows increase a home’s value, how much they increase it can vary. It depends on the age of the home and the type of windows. You can expect about 70% to 85% return on investment (ROI) when adding a window to your home.

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.
