Plumbing repair details detailsServices
Cahill’s Plumbing & Heating runs plumbing repair, clogged drains, leak detection, 24-hour emergency service, water heater installs and septic care out of two liveried trucks working Maple Valley, Kent, Renton, Bellevue and Seattle. Every estimate is free and priced before the work starts, and the crew that answers the phone at (425) 432-1977 is the same crew that shows up in the truck.
The three jobs below are the ones that build a reputation: getting the truck out at 2 a.m., finding a leak before anyone digs, and installing a water heater without pushing a brand. Plumbing repair, clogged drains and septic work sit further down as a quick index, but they get exactly the same crew and the same free estimate.

Emergency service
A burst pipe, a water heater dumping onto the garage floor, a sewer backing up into the lowest drain in the house: Cahill’s is open 24 hours, every day, and (425) 432-1977is answered by a person whatever time it rings. Shut off the main water valve if you can reach it, and the gas or power to the water heater if that is the source, while a marked Cahill’s truck is on the way.
A same-night callout stops the bleeding. If a temporary fix is what gets a household through the night, the proper repair gets finished the next day, at the price quoted, with no flat-rate gimmick added once the truck is already in the driveway.

A water bill that climbs for no reason, a meter that keeps spinning with every fixture in the house off, or a patch of lawn that never dries out, all point to a leak somewhere between the meter and the house, or inside a wall or slab. Cahill’s locates the leak first, before anyone starts digging.
One customer’s water-line leak had someone on site within an hour of the first call, was located the next day, and by day three a single trench had been dug, the pipe repaired and the trench filled back in well enough that you could barely tell it had been opened.

Water heater
Tank and tankless installs both run through Cahill’s, including Rinnai tankless units and Bradford White gas tanks set on a proper stand, with venting, gas and water connections and the T&P discharge line done right the first time.
Customers choose their own model. One review specifically called out that Cahill’s let the customer pick a Rinnai tankless instead of steering them toward whatever the crew wanted to sell, and still came in well under the big multi-state outfits on price.

Most of the jobs above start with something already broken. Cahill’s also runs a standing maintenance program built to catch the problem before it gets to that point:
