Lamontagne Overhead Door

Lamontagne Overhead Door is a garage door installation, maintenance and repair company based in Merrimack, NH, serving homeowners across Southern New Hampshire. Day-to-day service is handled by "Carl" and a technician customers refer to as "CJ," covering routine service calls, opener repairs, and full door replacements. Reviewers consistently describe fast response times, several noting they were seen within a day or two of calling, or the same day for an urgent repair such as a garage door damaged backing out of it. Pricing comes up often and favorably — homeowners describe quotes lower than expected and repeatedly call the work fair and reasonably priced. The crew is also credited with leaving job sites clean, with one reviewer noting the area looked untouched once the work was finished. Jobs described range from quick fixes to full door replacements, including one reviewer whose garage doors were close to 30 years old before being repaired rather than replaced outright. New Hampshire has no statewide licensing requirement for garage door contractors, so there is nothing to verify on that front. There isn't much of a track record to weigh yet — all ten reviews on file are five stars and date from mid-2025 onward — but for a straightforward garage door repair or replacement in the Merrimack area, the reviews point to prompt scheduling and fair pricing as the consistent draw.
