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 Extinguisher Inspection & Service FAQ
How often do commercial fire extinguishers need to be inspected in New Hampshire?
Per NFPA 10 and New Hampshire state fire codes, commercial fire extinguishers require three levels of inspection: a monthly visual check (can be done by the owner), a comprehensive annual professional inspection, and periodic internal maintenance (usually every 6 or 12 years depending on the type). LHR Fire Protection provides the certified annual tagging and documentation required for business compliance.
What is included in a professional fire extinguisher annual inspection?
Our certified technicians perform a multi-point check, including verifying the pressure gauge is in the “green,” checking the pull-pin and tamper seal, inspecting the hose for blockages or cracks, and ensuring the physical canister is free of corrosion. We then provide the required dated inspection tag that fire marshals look for during their walkthroughs.
Do you provide fire extinguisher sales and installation in Manchester and the Seacoast?
Yes! We don’t just inspect; we help you determine the correct type and quantity of extinguishers needed for your specific layout. Whether you need an ABC Dry Chemical for an office in Manchester or a Class K for a commercial kitchen in Raymond, we supply, mount, and tag your equipment to ensure full coverage.
When should a fire extinguisher be replaced instead of recharged?
Most modern extinguishers can be recharged after use, but they should be replaced if the cylinder shows signs of rust, if the handle is wobbly, or if the nozzle is cracked. If you have an older “disposable” plastic-head unit, these cannot be serviced and must be replaced after 12 years or any use. Our team can evaluate your current inventory and recommend the most cost-effective solution.

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.
