"My Frenchwood sliding patio door was installed today. The door is high quality, and the installation went smoothly with no issues. I am very happy. I had 16 windows replaced over the past 2 years by this company and highly recommend RBA of Eastern NY."

"We are pleased with the products we received BUT the road from start to finish was long and frustrating. Signed contract 6/11/17, installation was 8/14/17 no biggie except we were told 30 days not 60 and we had to make few calls to press for the date we got. The installer cracked a window during installation. Again no biggie,sh*t happens. The "rush" on the replacement window took several follow up calls to get an another installation date of 9/29/17. My husband takes off, two guys show up without the window and said they thought they were doing a service call. My less then professional conversation with John the manager led to another appointment for the next day. The guy shows up, replaces the window but doesn't have the "j" channel to complete the job. Two days later I get a call to reschedule yet another appointment 2 weeks out and that I had to be home. The rep had no idea the last piece of the work only required outside access and even when I explained he still insisted I needed to be home. One last conversation with the acting manager (I was told John was on vacation) and we were scheduled for the following week which was 10/9/17. The job was completed that day and I was left with pieces of "j" channel in the flower bed. The other criticism would be the length of time spent on hold with customer service; with all the calls I had to make I was NEVER able to complete an entire call on my 15 min. break."

"Complete Contracting came and replaced the roof on my house and cleaned out the gutters after. They were very professional and courteous. They came and did the work in a timely manner with all the proper equipment needed to do the job. I highly recommend them and would definitely use them again."

"The installation was completed quickly and efficiently and with high quality. The door include a pet door/flap too. On that note, make sure you a size that fits your pets. I have a medium size dog and her won't fit, and the person that ordered the door saw my pet, so not sure how the size turned out to be too small. However, I also have 4 cats and they can use the flap and I decided it was not the end of the world. I am still overall happy with the service and the overall door install."

FAQs for doors (exterior) installation and replacement projects in Windham, NY

If your entry bakes in direct sun, fiberglass is the clear winner. The material shrugs off extreme heat, stays energy-efficient, and won’t warp or fade the way wood sometimes can. Paired with low-E or UV-blocking glass, a quality fiberglass door keeps hot air out, cool air in, and should serve you reliably for roughly two decades.

A seasoned door pro can hang a replacement door in two to four hours—mounting the slab, tweaking the fit, and adding hinges, knobs, and weatherstripping. If the jamb needs repairs or you’re cutting a brand-new opening, plan on extra time so everything lines up and seals tightly. Either way, most projects wrap up in a single afternoon.
