Drain Cleaning & Clog Removal
Slow drains, recurring backups, and main-line clogs. We use motorised drain machines and hydro-jetting to clear tree roots and grease, not just push them down the line.
Drain cleaningLocal, licensed plumbers for Centennial homes and businesses. Drains, water heaters, leaks, and sewer lines — diagnosed fast, quoted in writing, done right the first time.
Grig Plumbing is a licensed, owner-operated plumbing company serving Centennial, CO and the surrounding Arapahoe County area. We handle drain cleaning, water heater repair and installation, leak detection, pipe repair, and sewer line work for homes and businesses, with free estimates and a written price agreed before any work begins.
Finding a reliable plumber in Centennial shouldn’t feel like a gamble. National franchises treat you like a ticket number, and a general handyman rarely has the diagnostic gear a real plumbing system needs. Based just next door in Aurora, we reach most Centennial neighbourhoods in minutes — from Southglenn and Willow Creek to Piney Creek, Smoky Hill, and Cherry Knolls.
Whether it is a dripping faucet, a water heater that quit overnight, or a sewer line backing up into the basement, you get local knowledge, proper equipment, and honest answers about what the job actually needs.
The full range, from a five-minute faucet fix to a trenchless sewer replacement. Tap any service to see how we handle it.

Sewer & water linesBurst pipes, gas line issues, and sudden water heater failures don’t keep business hours. We dispatch fast to limit the damage, day or night.
Emergency serviceToilets, faucets, sinks, garbage disposals, and fixture upgrades. Everyday plumbing done cleanly, with the old unit hauled away.
Bathroom & kitchenThis is the detail most plumbers miss. Centennial homes are served by different water providers, and the water hardness — the thing that wears out heaters and clogs fixtures — changes depending on which one you have.
Much of Centennial draws on Front Range reservoir and snowmelt supply, which Denver Water classifies as soft to moderately hard. Gentler on tanks and fixtures, but scale still builds over years.
Varies by neighbourhood and provider
The eastern ZIPs around 80015 and 80016 sit in Aurora Water territory, which runs very hard — roughly 260 ppm, over 15 grains per gallon. That is aggressive on water heaters and the top reason for a softener conversation here.

Why it matters for your bill. Very hard water plates scale onto water heater elements and inside tankless heat exchangers, and it crystallises in faucet aerators and toilet rim jets. In the hard-water ZIPs, a heater can lose real efficiency in just a couple of years. We factor your actual supply into every water heater and fixture recommendation — not a one-size-fits-all guess. Not sure which provider serves you? Ask us, and we’ll tell you what your plumbing is up against.
Centennial sits even higher than the Mile High City. At altitude, gas water heaters need correct venting and combustion setup, or they backdraft and burn inefficiently. We size and vent for elevation as standard.
Neighbourhoods like Palos Verdes, Highland 460, and Willow Creek were largely built before the Lead and Copper Rule. Local guidance flags any Centennial home built before 1987 as a lead-pipe risk worth checking.
Front Range clay expands and contracts with moisture, stressing buried water and sewer lines. It is a common cause of the slab leaks and line breaks we trace across the south metro.

Minor work such as a drain unclog, faucet repair, or fixture swap generally falls in Grig Plumbing’s published $150 to $400 range. Larger jobs like water heater installation or sewer line work run higher, typically $800 to $3,000 or more. We provide a free estimate and a written price before any work starts, so you always know the cost up front.
We offer same-day scheduling and 24/7 emergency service across Centennial and Arapahoe County. Because we are based next door in Aurora, we reach most Centennial neighbourhoods quickly — often within a couple of hours for urgent calls, and active leaks and total outages get priority.
It depends on your provider. Centennial is served by more than one water system. Areas on Denver Water and some south-metro supplies run soft to moderately hard, while the eastern ZIPs around 80015 and 80016 sit in Aurora Water territory, which is very hard at roughly 260 ppm (over 15 grains per gallon). Hard water is the main reason water heaters and fixtures wear out early here, so it is worth knowing which supply you have.
Some may. Several Centennial neighbourhoods — including Palos Verdes, Highland 460, and Willow Creek — were largely built before the EPA’s Lead and Copper Rule, and local guidance flags homes built before 1987 as a lead-pipe risk. If you have a leak on an older service line, it is worth identifying the material before repairing it. We check as part of the diagnosis.
Yes. Grig Plumbing is fully licensed and insured in Colorado. We are owner-operated, so the person quoting your job is the person doing it — not a rotating crew from a national dispatch centre.
No. Estimates are free. We assess the job, explain what it needs, and give you a written price before starting. For simple jobs you can often text us photos and get a ballpark before we even drive out.
All of them, plus the surrounding south metro. That includes Southglenn, Willow Creek, Piney Creek, Smoky Hill, Cherry Knolls, Walnut Hills, Heritage Greens, Foxridge, Palos Verdes, and Highland 460, across ZIP codes 80015, 80016, 80111, 80112, 80121, and 80122.
Both. From a single faucet repair to a full water heater or sewer line replacement. If a repair is the smarter call, we will tell you — we would rather keep you as a customer than sell you a replacement you did not need.
Fast, friendly, and upfront. Free estimates, written pricing, and a licensed local plumber who treats your home like their own.
