Most installations are same-week — often 1–2 business days from your request. On-site, a standard door installation takes 3–5 hours.

For comparison, national big-box stores and many chain installers quote 3–4 week lead times. We don't work that way.

Classic signs of a broken torsion spring:

· You heard a loud bang from the garage (often described as a gunshot crack)
· The door opens 6 inches then stops
· The door feels extremely heavy when you try to lift it manually
· There's a visible gap in the coil above the door

Don't force it. A door with a broken spring puts enormous stress on the opener and cables. Call us — this is a same-day repair in most cases.

Repair when: door is under 15 years old, panels are structurally sound, and the problem is mechanical (spring, cable, opener).

Replace when: panels are cracked or dented, the door is 20+ years old, you've repaired it multiple times recently, or you want better insulation, lower energy bills, or updated curb appeal.

A good rule: if repair costs more than 50% of a new door, replace it. Request a free estimate to see what a new door would cost — then compare.

The most common cause: a broken spring. The motor runs, but the broken spring means the door is too heavy to lift. Second most common: the disconnect rope was pulled (there's a red cord hanging from the trolley — if it was pulled, the door runs in manual mode and the opener isn't connected).

Check the disconnect first — reconnect by pulling the cord toward the door until it clicks. If the door still won't open or feels very heavy, stop. Call us.

Chain drive: Uses a metal chain — reliable, affordable, and built for years of use. The tradeoff is noise. Fine for detached garages.

Belt drive: Rubber belt instead of chain — noticeably quieter and smoother. Best if the garage is under a bedroom or living space.

Direct drive / jackshaft: The motor travels along a stationary chain, or mounts to the side wall — the quietest option with the fewest moving parts. Higher upfront cost, lower long-term maintenance.

A well-maintained garage door lasts 15–30 years depending on material and usage. Key components wear sooner:

· Springs: 7–10 years (10,000–20,000 cycles)
· Openers: 10–15 years
· Cables: 8–12 years

Annual lubrication (hinges, rollers, springs) and a quick visual check each season can add years to every component.

Insulated steel is the best overall choice for New England — it handles freeze-thaw cycles, salt air, and humidity without warping or cracking. Look for R-value 12–18 for attached garages (it makes a real difference on heating bills).

Wood composite gives a traditional carriage-house look without solid wood's maintenance headaches. Holds up better in coastal and high-humidity locations than real wood.

Avoid uninsulated steel or solid wood if you're near the coast or the garage is temperature-controlled.

Often yes. If your opener is less than ~15 years old, we can typically add a smart WiFi module (like MyQ) that connects to your phone — no full replacement needed. Adds app control, open/close alerts, and Amazon Key access.

If your opener is older or incompatible, upgrading to a new smart opener runs about $300–$450 installed and is usually worth it — you get a warranty, better safety sensors, and modern features.
