Frequently Asked Questions

You call, we listen to what the door is doing or not doing, and we set a time to come look. A live coordinator answers and connects you with the local team. We arrive inside the window we gave you, diagnose the exact issue, and put the price in writing before any work starts. Once you approve, we fix it, test it, and leave the site clean and squared away. That's The Garrison Code, and it applies to every job we do in Hempstead and the surrounding Nassau County area.

Yes. Estimates are free. For repairs, the estimate is the exact written price you'll pay before we touch a tool. For new door installations, we come out, take measurements, show you options, and write up a firm quote at no charge. You get the full picture before you spend a dollar. Call (516) 559-5490 to set up a free estimate at your Hempstead home.

Most common repairs, like springs, cables, rollers, or opener issues, take 60 to 90 minutes once we're on site. Some jobs, like replacing a full panel or rebuilding track, run longer. New door installations typically take one day once the door arrives. We give you a straight time estimate when we schedule, and we show up inside the window we promised. No waiting around wondering if anyone's coming.

Repair is the right call when the door's structure is sound and the issue is mechanical: springs, cables, rollers, hinges, or an opener. Replacement makes sense when the door is dented, rusted, sagging, or you're tired of a drafty single-panel door and want insulation. A good rule: if the repair cost is more than half the cost of a new door, or the door is over 15 years old, replacement is worth a serious look. We'll give you an honest read either way.

It doesn't. The price we put in writing before any work starts is the price you pay. If we find something unexpected, we stop, show you what we found, and write up a new price for the additional work. You approve it before we proceed or you don't, and we only do what you've agreed to. That's the whole point of The Garrison Standard. No price moving at the door, ever.

We install, repair, and maintain all major brands, including Wayne Dalton, LiftMaster, Craftsman, and Raynor. Most garage door systems in Hempstead homes are built around one of these names, and we keep common parts for them on hand. If your door is an older or off-brand model, we can usually source what it needs within a few days. Tell us what's on your door and we'll tell you exactly what we're working with.

Yes. Our local team stocks the most common repair parts right on the truck: torsion and extension springs, cables, rollers, hinges, brackets, safety sensors, and opener components. That means most repair calls in Hempstead are done in one trip. If your door needs an uncommon part or a custom-sized spring, we order it and schedule a follow-up as soon as it arrives. No multiple-week waits for basic repairs.

LiftMaster builds the most durable belt-drive and chain-drive openers we see in Hempstead, and they're the ones we recommend most often. Belt-drive models run quieter, which matters if you have a bedroom above the garage. Chain-drive models cost less and last just as long when installed correctly. Whatever brand you pick, the install quality and the balance of the door itself matter as much as the opener. A well-installed opener on a badly balanced door won't last.

We can repair most older garage doors as long as the panels and track are structurally intact. Springs, cables, rollers, and hinges are wear parts meant to be replaced over the life of a door. What we can't fix is rust that's eaten through the metal, panels that have lost their structural integrity, or track that's bent beyond alignment. We'll tell you straight what's worth fixing and what's better replaced.

Every pro working under our name is required to hold the license and insurance their state requires. That's a condition of operating as a Brock Garage Door Repair brand location, and it's part of what The Garrison Standard means. When you book with us, you're not rolling the dice on who shows up at your door. You get a service-owned local team that's held to a standard, not a random referral.

Each Brock Garage Door Repair location is independently owned and operated, and every tech working under our name is required to meet the licensing and insurance requirements of their state. We take seriously the trust you place in us when you let a crew into your home. The Garrison Code is built on discipline: show up on time, do the job by the book, leave the site clean. That discipline extends to who we put on your job.

Brock Garage Door Repair is the garage door company of the Garrison Partners family. The name comes from a plain, solid surname that sounds the way a good garage door should: strong and no-nonsense. Each location is an independent local business that agreed to work to The Garrison Standard. Our Hempstead location is led by Wade Mercer, who brings the brand's discipline to homeowners across Nassau County.

It depends on what today looks like. We run a real schedule, and we don't overbook to squeeze in extra calls we can't actually serve. Our hours are Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. Call (516) 559-5490 as early as you can, and if we have an opening, we'll get you on the schedule. If not, we'll give you an honest window and show up inside it.

First, don't try to open the door manually. A snapped spring means the door's weight isn't balanced, and it can come down hard. Do not attempt to replace a torsion spring yourself. These springs are under extremely high tension, and a wrong move can cause serious injury or worse. Call us at (516) 559-5490 and we'll get a trained professional out to replace the spring and rebalance the door. This is a job for someone who does it every day, by the book.

No. Our hours are Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed Saturday. We don't run an after-hours call center or promise service we can't deliver. What we do promise is this: when you book with us, we show up inside the window we gave you, and the job gets done right. Call (516) 559-5490 during business hours for fast, dependable scheduling.

Yes. A broken torsion spring is a genuine safety hazard. The spring holds hundreds of pounds of tension, and when it snaps, that energy releases at once. Worse, a door with a broken spring is unbalanced, which means it can slam shut unexpectedly and cause serious injury to anyone underneath it. If you hear a loud bang from your garage and the door won't lift, stop using it and call a trained professional. This is not a DIY project.

The Garrison Standard is the promise every Garrison company works to. We arrive inside the window we gave you, put the price in writing before any work starts, do the job by the book the first time, and leave the site clean. The work is guaranteed in writing for a full year, and if it fails in that time, we come back and make it right at no charge. It's not a marketing slogan. It's the operating code of every Brock Garage Door Repair location.

Your garage door repair is guaranteed in writing for a full year. If the part or the workmanship fails within that year, we come back and make it right at no charge. It's that simple. The guarantee covers the work we did and the parts we installed. It doesn't cover new damage, misuse, or normal wear on parts we didn't touch. When we do a job in Hempstead, we stand behind it. That's the deal.

The openers we install carry the manufacturer's warranty on the unit itself. Our workmanship installing it is guaranteed in writing for a full year under The Garrison Standard. If the install was the problem, we come back and fix it at no charge. If the opener itself fails under warranty, we handle the replacement process and get you running again. Either way, you're covered for a year, in writing.

We're based in Hempstead and serve homeowners across central and southern Nassau County, including Flushing, Rockville Centre, Bayside, Levittown, Plainview, Massapequa, North Massapequa, Freeport, Hicksville, East Meadow, and Long Beach. If you're in Hempstead or a neighboring community and your garage door is acting up, call (516) 559-5490. If we can't get to you, we'll tell you straight instead of stringing you along.
