Great service from start to finish. From my first call with Allie, to the electrical service performed by Brandon and Sam, which was unctual, skillful, and professional. Everyone I dealt with at LHR Electrical was very efficient and adept. Would definitely recommend and use again.

Fire Sprinkler Maintenance & Inspection FAQ
How often do commercial fire sprinkler systems need to be inspected?
Most commercial systems require a quarterly visual inspection and a more rigorous annual physical test of the valves, alarms, and backflow preventers. Regular inspections are not just a safety requirement but often a requirement for your insurance policy.
What is involved in a fire sprinkler "Main Drain" test?
During an annual inspection, our team performs a “Main Drain” test to check for any obstructions in the water supply and to ensure there is adequate pressure to support the system in the event of a fire.
Do you service residential fire sprinklers in NH?
Yes! We provide maintenance and inspections for both residential and commercial fire sprinkler systems. Home systems are vital for life safety and require specialized knowledge to maintain correctly.
What should I do if my fire sprinkler system starts leaking?
If you notice a leak, contact LHR Fire Protection immediately. Small leaks can lead to significant water damage or system failure during an emergency. We provide reliable support to get your system back in top condition.

Our Clients Say
Posted on Paul DuclosTrustindex verifies that the original source of the review is Google. This company was absolutely outstanding to work with throughout our entire commercial renovation project. They are professional, provide a very reasonably priced service, handle all your fire safety needs, and are always there even in emergency last minute situations. We hired LHR Fire Protection to raise our sprinkler main in our warehouse space and rework the branch lines. The project did even start yet and one of our other contractors (not affiliated with LHR) broke a sprinkler head during demo. Josh from LHR was there within the hour to cap it off and get the rest of the building back up and running even though the ink from our contract hadn't even dried yet! They met all of our deadlines, were at every inspection on time, and surpassed our expectations with their impeccable service. Because we had such a great experience with them we are continuing to use them for our fire extinguisher annual inspections and know that we are in great hands. Thank you to everyone we worked with at LHR Fire Protection you truly deserve more than 5 stars!Posted on Barry SwansonTrustindex verifies that the original source of the review is Google.
