Frequently Asked Questions

Most standard repairs, spring replacements, cable fixes, and roller swaps take 60 to 90 minutes from the time we arrive. We carry the common springs, cables, and openers on our truck so we can finish in one visit. Larger jobs like full door replacements or custom installations in historic neighborhoods like Brooklyn Heights may take a half day. We'll give you a clear timeline when we quote the job. Call (877) 379-8821 to book.

We arrive on time, protect your driveway and garage floor, remove the old door if needed, install the new door and hardware, connect the opener, and tune everything to run quiet and true. Then we walk you through the operation, safety features, and maintenance basics. We don't leave until you're comfortable with how it works. Every door we touch gets the same care, whether it's in a Park Slope brownstone or a Long Island City condo building.

Yes, we've worked on doors in pre-war buildings, converted carriage houses, and landmarked properties across Chinatown, the East Village, and Gramercy Park. Older structures often have non-standard openings, low headroom, or masonry headers that require custom solutions. We measure twice, fabricate or source the right hardware, and install it without damaging original architectural features. Call (877) 379-8821 to discuss your building's specific needs.

Yes, we need an adult present to approve the work, provide access, and review the finished job with us. We don't let ourselves into an unattended garage. If your schedule is tight, we offer scheduling flexibility across all seven days, and our phone is answered 24/7 to find a time that works. Call (877) 379-8821 to arrange your appointment.

New York City's humidity swings, salt air in coastal neighborhoods, and freeze-thaw cycles in winter wear on garage doors faster than in milder climates. We recommend annual lubrication of rollers, hinges, and springs; inspection of cables for fraying; and testing the auto-reverse safety feature. In waterfront areas like Greenpoint and Williamsburg, we see more rust on bottom fixtures and recommend more frequent checks. A well-maintained door lasts years longer and avoids emergency calls. Ask us about a maintenance visit when you call (877) 379-8821.

We install and service Clopay, Amarr, Wayne Dalton, and Genie doors and openers, among others. These are brands we've found hold up well in New York City's demanding conditions, from the heavy use of multi-unit buildings in Hell's Kitchen to the salt-air exposure in waterfront neighborhoods. We don't push one brand over another. We match the product to your door size, usage pattern, budget, and aesthetic preferences. Call (877) 379-8821 to see samples and discuss options.

We use OEM parts whenever possible, especially for springs and cables where precise engineering matters for safety and longevity. Generic springs with the wrong wire gauge or cycle rating fail early and can damage the door. We source from Clopay, Amarr, Wayne Dalton, and Genie authorized distributors. If an OEM part is discontinued, we find the closest engineered equivalent and explain the substitution before we install it. No shortcuts. That's Krafted right, the K in our K.E.Y.S. code.

Often, yes. If the opener is under 10 years old and the issue is a worn gear, faulty sensor, or logic board failure, repair is usually cost-effective. If the opener lacks modern safety features, has repeated failures, or is a brand we can't source parts for, replacement is the smarter long-term choice. We diagnose the actual problem, explain both paths, and let you decide. Call (877) 379-8821 for a free assessment.

Every pro working under our name is required to hold the license and insurance their state requires. We verify coverage before anyone goes out on a job. For our customers in New York City, this means protection against property damage, injury, or faulty workmanship. We don't send anyone to your home who isn't properly credentialed. It's part of how we've operated since 2016.

Most standard repairs, spring replacements, and opener installations don't require permits. Full door replacements in landmarked districts or buildings with specific co-op or HOA rules may need approval before work begins. We've navigated these requirements in historic neighborhoods like Gramercy Park and Brooklyn Heights, and we can advise you on what's needed for your specific property. Call (877) 379-8821 and we'll walk you through it.

Yes, we offer same-day service across our full New York City area, including Manhattan, Brooklyn, Queens, and into Hoboken. Our phone is answered 24/7, and our local team carries the parts to handle most spring, cable, and opener failures in a single visit. We don't guarantee a specific arrival window, but we prioritize emergencies and communicate honestly about timing. Call (877) 379-8821 and we'll get you sorted.

A door stuck open with your home exposed, a door that won't close and is trapping your car, a broken spring with the door hanging crooked, or a snapped cable with the door off-track are all emergencies. These situations create security risks, safety hazards, and inconvenience. We treat them seriously and respond as quickly as we can. If you're unsure whether your situation is urgent, call (877) 379-8821 and we'll help you figure it out.

Yes, and you should not attempt to operate it until we do. An off-track door is under extreme tension from the springs, and forcing it can bend the track, damage the door panels, or cause the door to fall. We secure the door, identify why it came off track (usually a broken cable, worn roller, or impact damage), realign everything, and test the full system before we leave. This is not a DIY job. Call (877) 379-8821 for safe, professional repair.

Every job we complete is backed by The Keystone Standard: 90 days, in writing, no arguing. If something isn't right, we come back and fix it. No paperwork battle, no runaround. For new door installations, manufacturer warranties from Clopay, Amarr, Wayne Dalton, or Genie apply on top of our guarantee. We've stood behind our work this way since 2016, and we don't plan to change.

It means if you call us within 90 days and something we did isn't performing as it should, we come back and make it right. We don't debate whether it's our fault, ask you to fill out forms, or point to fine print. We fix it. Standing behind it is the S in our K.E.Y.S. code, and it's how we've built trust in this community for over four decades. Call (877) 379-8821 with any concern, and we'll handle it.

Manufacturer warranties typically cover the part itself, not the labor to diagnose, remove, and replace it. Our 90-day Keystone Standard covers our labor, so if a part we installed fails due to our workmanship, both the replacement and the labor are on us. If the part fails due to a manufacturer defect after our 90-day period, we can replace it at fair labor rates and help you pursue any remaining manufacturer coverage. We'll always explain where you stand before we start any work.

Check how long they've been in business and whether they have a local presence you can find. A company that's been around two years and has no fixed address may not be there when you need them. We've been serving New York City since 2016. Our phone is answered 24/7. Our trucks are local. Our name is on the work. That's the difference between a promise on paper and a company that plans to be in town in thirty years.
