Drain Cleaning
Slow drains, recurring backups, and main-line clogs. We use motorised drain machines and hydro-jetting to clear roots and grease — common in the older sewer laterals around Derby and Rose Hill.
Drain cleaningLocal, licensed plumbers for Commerce City homes — drains, water heaters, leaks, and the very hard water this part of the north metro is known for. Diagnosed fast, quoted in writing, done right.
Grig Plumbing is a licensed, owner-operated plumbing company serving Commerce City, CO and the surrounding north Denver metro. We handle drain cleaning, water heater repair and installation, leak detection, pipe repair, and sewer line work — with real experience in the area’s very hard water and its mix of older and new-build homes. Free estimates, written pricing before any work begins.
Finding a reliable plumber in Commerce City 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 in Aurora, a short run up into the north metro, we cover the whole city — from the original neighbourhoods of Derby, Rose Hill, and Adams City to the newer master-planned communities of Reunion, Buffalo Run, and Belle Creek.
The city sits in the South Platte valley in Adams County, north of Denver, and it has grown fast — but one thing is constant across the whole city: the water is very hard. More than anywhere else in the metro, that shapes how we protect your plumbing here.

Slow drains, recurring backups, and main-line clogs. We use motorised drain machines and hydro-jetting to clear roots and grease — common in the older sewer laterals around Derby and Rose Hill.
Drain cleaningNo hot water, leaks, or a tank past its prime. With water this hard, heaters scale fast — so repair, flushing, and replacement matter more here. We install tank, tankless, gas, and electric.
Water heatersHidden leaks in walls or under slabs cost thousands if ignored. We locate them acoustically before cutting, then repair with minimal disruption — including repiping in older homes here.
Pipe repairFrom camera inspections to trenchless sewer replacement, we handle the big underground jobs — and tell you honestly when a repair beats a full replacement.
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 — very hard water is tough on fixtures here, so we help you choose parts that hold up.
Bathroom & kitchenCommerce City’s water comes largely from deep groundwater wells, and it is genuinely, measurably hard — harder than almost anywhere else on the Front Range. That single fact drives most of the plumbing work we do here.
South Adams County Water & Sanitation District — the largest combined water and sanitation district in Colorado — has reported an average hardness of about 21 grains per gallon (roughly 359 mg/L). That is very hard, about double the threshold, drawn from deep aquifer wells and blended with treated Denver Water.
What water this hard actually does. At 21 grains per gallon, dissolved calcium and magnesium plate scale onto water heater elements and inside tankless heat exchangers fast, clog aerators and rim jets, and cut appliance life short. Here more than anywhere, we recommend regular water heater flushing and the correct anode rod — and, unlike some towns, a softener is often a reasonable option worth pricing out. We’ll test your water and give you a straight answer. See how we handle water heater repair and installation.
The historic south — Derby, Rose Hill, Adams City — has older homes with aging pipe and sewer laterals. The North Range, including Reunion and Buffalo Run, is new-build territory from the 2000s on. We work on both, and the issues differ by area.
Most of the city is served by the South Adams County Water & Sanitation District, the largest combined water and sanitation district in the state. Knowing the local system helps us advise you accurately on hardness and pressure.
The city sits lower and flatter than the south metro, down in the South Platte valley. It is still high enough that gas water heaters need proper high-altitude venting — which we set up as standard.

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, repiping, or sewer line work run higher, typically $800 to $3,000 or more. Older homes in the original neighbourhoods can add scope, and hard-water damage sometimes means a fixture needs replacing rather than repairing. We give a free estimate and a written price before any work starts.
Yes — some of the hardest in the metro. The South Adams County Water & Sanitation District has reported an average hardness of about 21 grains per gallon (roughly 359 mg/L), which is very hard, drawn largely from deep groundwater wells. Practically, that means scale builds fast on water heaters, fixtures, and appliances, so regular water heater flushing and the right anode rod matter more here than almost anywhere.
Given how hard the water is here, a softener is often a reasonable option worth considering — more so than in softer-water towns. That said, it depends on your household, your appliances, and how long you plan to stay. Rather than selling one to everyone, we test your water, walk you through the trade-offs, and also make sure the basics — heater flushing and the correct anode rod — are handled either way.
Most of the city is served by the South Adams County Water & Sanitation District, the largest combined water and sanitation district in Colorado. Its supply comes largely from deep aquifer wells, blended with treated water purchased from Denver Water. The result is a very hard supply, which is the main plumbing factor to plan around.
Yes — both are common here. The original neighbourhoods like Derby, Rose Hill, and Adams City have older homes with aging galvanised pipe, cast-iron drains, and older sewer laterals. The North Range communities such as Reunion and Buffalo Run are newer builds with PEX and modern fixtures. We’re experienced across both, and the likely issues differ by area.
We offer same-day scheduling and 24/7 emergency service across the city and the north metro. Based in Aurora, a short run up into the area, we reach most of it quickly — often within a couple of hours for urgent calls, with active leaks and total outages given priority.
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 north metro. That includes Reunion, Buffalo Run, Belle Creek, Second Creek, River Run, Derby, Rose Hill, and Adams City, across ZIP code 80022 and the nearby 80640 and 80603 areas.
