Professional Garage Door Spring Repair in Portsmouth, NH

We almost always recommend the matched pair, even if only one snapped. The other spring has the same age and cycle count and is usually months from failing. Doing both in one visit keeps the door balanced and means the next break won't happen with your car trapped inside.

Yes — a same-day fix in most cases. Symptoms: the door hangs at an angle, barely opens then stops, or you heard a loud bang followed by the door dropping a few inches. The tech re-spools the cable on the drum, tests tension, and replaces both cables if either is frayed.

Usually a dead remote battery, a remote that needs reprogramming, or a receiver issue in the opener head. We carry universal remotes and keypads that work with LiftMaster, Chamberlain, Genie, Marantec, Craftsman, and most older Wayne Dalton units — reprogramming is a 10-minute job on any service call.

The two photo-eye sensors near the floor must see each other in a straight line. Common causes: one knocked out of alignment, a dirty lens, a kinked wire, or sun glare. Wipe both lenses and check alignment; if that doesn't fix it, a sensor or the wire run is bad and we replace it on-site.

Yes — single-car 8x7 and 9x7, double-car 16x7, and oversized 18-footer and 14-foot RV doors. Custom doors take longer lead time on the door itself, but install is the same day as delivery. Every new-door quote starts with a free on-site measurement and a written firm price.

Often, yes — if the rest of the door is structurally sound and we can source a matching panel. Single-panel replacement is meaningfully cheaper than a full new door. The tech checks panel availability and color match during the free inspection.
