"Easy process from quote to work complete. The crew worked on a few small projects -- fixed a damaged wall, repaired flooring, and installed a new toilet."

"Nixon responded quickly and was able to install a new back storm door for us. The only problem is that it looks nicer than the front door now! :) Excellent work! Hired him to do several projects at Mom's now!"

"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

"Exceptional work! I sent in my request for the job and they came within a day and a half, got the job done in just a few hours. They are also open to all your opinions and critiques. Their customer service and punctuality was really great. It took me and my family days and hours to try and do the job ourselves, but Mastak are pros. My doors look so good! Thank you so much!"

"Nathan does tremendous work, at a fair price, and in a timely manner. We had a section of our exterior rot out under our siding and he made the necessary repairs with a quick turn around, and also took steps to mitigate the risk of this issue occuring again. We would recommend Nathan to our friends and family any day."

"We had a great experience working with John from Happy Wife installing custom closet doors in our master bedroom. We received four quotes, and John stood out as the only contractor who offered a reasonable price while still delivering high-quality work and keeping the existing structure of our closet intact, while other contractors suggested unnecessary structural changes. John took the time to walk us through the entire process and made sure the doors came out exactly how we envisioned. He even upgraded the quality of the doors to make them more sturdy and durable. He was professional, transparent, and great to work with from start to finish. The craftsmanship is excellent and the doors completely transformed the space. I look forward to using his for future home reno projects. Highly recommend!"

FAQs for doors (exterior) installation and replacement projects in Derby, CT

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.
