"Chapin Handyman does excellent work! We needed our basement windows (which had just been replaced by another contractor) to have either a trim border or wallboard put around them and decided to get caught up on a few other tasks that we just weren't getting around to. Nestor was very responsive for giving us a price, broken out by project. Each worker who came through (a) knew what was asked for from Nestor and also (b) double-checked the needs with us. The windows look *amazing* and we're really happy to have the ceiling fans switched out, our towel rack back up in the master bath, and the installation of a proper basement light switch (after making a bad call on not putting it in when we finished it years ago.) We can't recommend them enough!"

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"Extremely well from beginning to end. The written estimate (one of 3) was provided by David Rohrer on 11/25/19 a day or two after an on-time visit to determine my need, measure the windows and explain product choices as well as the process from start to end. After obtaining all 3 estimates, I chose Unicorp on 11/27/19 based on price, product (Vytex vinyl) and most importantly...past experience (Roof, Front Entry-way). The manufacturer's rep (Mike) came on 12/10/19 to measure more precisely and a mid-January 2020 installation was projected. Several calls to keep me updated were made by the installation team/manufacturer's scheduler and installation was scheduled for 01/22/20. The installation team was a 1/2-hour early (7:30am) and thereby was able to complete all the work on a sunny, mid-40 degree day with little wind as darkness closed in. The 3-man installation team team was professional, courteous and careful with both interior and exterior, landscaping, etc., and thoroughly cleaned up the premises, inside and out. The window installation also had to be timed with my home security vendor, both before and after installation and the window crew did was very careful to avoid creating problems. The windows look great, function as promised (mechanically and insulation-wise) and the +$18k was well spent. I highly recommend Unicorp for home energy services (windows, roofing, doors) and if I ever needed siding I would go with them again."

"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

To ensure the longevity and smooth functioning of new windows, regular maintenance is essential. This includes cleaning the glass and frames, inspecting seals for leaks or damage, and reapplying caulking as needed. It is also important to lubricate all moving parts and operating mechanisms to ensure they continue to operate smoothly.

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

A garage door screen can be a worthwhile investment, especially if you frequently use your garage for activities like a home gym, workshop, or other hobbies. It allows you to enjoy fresh air and natural light without worrying about bugs. Additionally, a screen provides ventilation that can improve air quality when you're working with paints, varnishes, or producing sawdust.

The best option depends on your usage. For occasional use, a DIY fabric screen is a low-cost, simple solution that you can put up and take down as needed. If you plan to spend a lot of time in the space, investing in a customized, professionally installed garage door screen can help transform the area into a new hub for your household.

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.

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.
