Leak Detection Reviews from Londonderry, NH

Real feedback from customers in Londonderry and surrounding areas who've called Ultimate Plumbing LLC for Leak Detection service.

★★★★★

"Kitchen sink backed up the night before Thanksgiving in Londonderry. Ultimate Plumbing LLC had a tech at my door within 90 minutes. He cleared the clog, ran a camera check downstream, and left no mess. Price was exactly what they quoted. This is what emergency service should look like."

Brenda W.
Londonderry, NH Homeowner
★★★★★

"Three plumbers gave me different estimates for the same water heater replacement in Londonderry — none of them explained what was included. Ultimate Plumbing LLC showed up, gave me a written flat price, replaced it the next morning. No confusion, no surprises."

JF
Jerome F.
Londonderry, NH Resident
★★★★★

"Camera inspection revealed the cause of two years of recurring drain problems in my Londonderry home — root intrusion 38 feet into the sewer line. Trenchless repair, done in one day, no yard damage. Should have called them first."

NP
Nina P.
Londonderry Property Manager
★★★★★

"Sump pump failed before a storm warning in Londonderry. Tech arrived at 7 AM with a replacement unit on the truck. Installed and tested before the rain hit. That timing probably saved my finished basement."

TM
Tracy M.
Londonderry, NH Homeowner
★★★★★

"On time, professional, and explained every step without using jargon to confuse me. The drain that had been backing up intermittently in Londonderry for months is completely clear. And I actually understand why it happened."

HS
Howard S.
Londonderry, NH Homeowner
★★★★★

"Had a slab leak in Londonderry that two previous plumbers couldn't locate. Ultimate Plumbing LLC used listening equipment, found it in 22 minutes, quoted the repair before touching anything, and completed it the same day. Documentation made my insurance claim simple."
