Portsmouth's Premier Garage Door Repair Service

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.

Lubrication of hinges, rollers, springs, and bearings; a balance check; spring-tension adjustment if needed; hardware tightening; safety-sensor verification; a reverse-on-obstruction test; and a cable inspection — about 45 minutes on a typical two-car door.

Once a year is the standard, especially with temperature swings, dust, or coastal salt air. The garage door is the largest moving part on most homes and cycles 1,500+ times a year — an annual tune-up extends spring life, catches problems early, and keeps a new-install warranty valid.
