"We couldn’t have replaced this door with a better expert. Ryan took measurements and photos, then recommended several doors in various price ranges. We didn’t realize how many options come with storm doors. Ryan gave us some really good recommendations and helped us make a great choice. He installed the door in a half day while we were out. Came back to a gorgeous door/screen storm door combo- something we weren’t even sure could have been done to begin with. Important to know:Throughout the entire process, Ryan was responsive and easy to reach. That’s vital in a world where ghosting is the norm (unfortunately). Ryan is the expert you need for your remodeling needs. Highly recommend!"

"Avi was a pleasure to deal with. I had a unique request: build a box to carry my French Bulldog on my cargo bike. Avi took my design and executed it to perfection, even matching the bike's paint. I was quite pleased with the result, and so was my dog!"

"We have hired Cesar and his team for several jobs now, and wouldn't consider anyone else. From first contact to the completed project, we were impressed. After having some bad experiences with contractors it was such a relief to find a team of professionals. Not only do they complete the project, but they went above and beyond. For instance, while shoring up our main staircase, Cesar fixed a door that never closed right, now almost a year later it still closes! The projects we hired him for were to replace loose tiles in our tub/shower and fix the faucets as well. Just yesterday they finished removing tile and carpet from our kitchen, hallway and bathroom. They also installed a combination of vinyl plank flooring, tile and a bathroom vanity. The job took only 2 days. Overall Cesar and his team worked quickly and efficiently, in a timely manner and they cleaned up afterward. I highly recommend this operation."

"I had a few things that I wanted done it all started with one bedroom window, five new window shutters and a front door shutter. The house being 41 years old needed a face lift. I also had them repair the front doorstep / sill. Family company that has a great crew and was able to complete everything in one day, I couldn't have been happier with the results and my wife is very happy to have all these repairs done. I highly recommend them and will use them in the future for other repairs"

Doors FAQs, answered by experts

After finishing a door installation or repair in Union, test all locks, hinges, and seals for smooth operation. Register any warranties with your installer. Within the first month, check for settling or misalignment and tighten hardware as needed. Schedule quarterly inspections, especially for exterior and garage doors, and update your home insurance if you’ve improved security or energy efficiency.

Helpful?

In Union, begin spring by inspecting for water damage and replacing worn weather seals. Summer is ideal for lubricating hinges and cleaning sliding door tracks to prevent sticking. In fall, check for gaps and install new door sweeps before colder weather arrives. Winter requires monitoring for drafts and ensuring garage doors operate smoothly despite snow or ice, especially in older brick homes.

Helpful?

In Union, ensure safety during door repair or installation by using childproof locks on interior doors and setting up sturdy, visible barriers to keep kids and pets out of work zones. For older homes, have door frames checked for lead paint before sanding or refinishing. Opt for low-VOC adhesives and paints, and always store sharp tools and hardware in locked containers when not in use.

Helpful?

Union’s climate, with its cold winters and humid summers, can cause wood doors to swell or contract, affecting door alignment and seals. Frequent freeze-thaw cycles may loosen frames, while summer humidity can stick doors shut. Heavy spring rains highlight the need for quality weatherproofing. Fiberglass or steel doors, paired with robust weather stripping, are ideal for Union’s variable weather.

Helpful?

New homeowners in Union should start by rekeying exterior doors and upgrading to high-security deadbolts. Consider replacing original doors in mid-century homes with insulated models to improve energy efficiency. Inspect and repair weather stripping to handle local humidity, and schedule a garage door tune-up. Don’t overlook sliding door track cleaning, especially in homes with older aluminum frames common in Union neighborhoods.
