Plumbing for Duluth homes and businesses
Carlson Duluth Company handles plumbing and heating service for homes and businesses across Duluth and the surrounding area. The Carlson family has done plumbing and heating in Duluth since 1905, and today the company is led by Jeremy Carlson, a licensed Master Plumber and an active member of the PHCC. Our plumbers are union trained and highly skilled craftsmen, so the same standard of work goes into a dripping faucet as into a full remodel.

Whether you own a house, manage rental units or run a business, the goal is the same: plumbing that is installed correctly, passes inspection and keeps working for years.
Signs it is time to call a plumber
Most plumbing problems give you some warning before they turn into water damage. Call us when you notice any of these:
- A faucet or fixture that keeps dripping after you have replaced the washer or cartridge
- Slow drains in more than one fixture, or gurgling when a toilet flushes
- Water stains on ceilings or walls, or damp spots under sinks and cabinets
- A water bill that jumps without any change in how you use water
- Low water pressure, rusty water, or hot water that runs out quickly
- A gas smell near an appliance, which calls for leaving the house and phoning the gas utility first
Duluth winters add their own problems. Freeze and thaw cycles can crack pipes in outside walls, crawl spaces and garages, and the leak often does not show until spring. Frost moving the ground can also stress underground lines and foundation joints.

- Faucet and fixture replacement, including toilets and sinks

Our process
Every job starts with listening. When you call, we ask what you are seeing, how long it has been going on and whether anything has changed recently, so the plumber arrives prepared. On site, we find the cause instead of treating the symptom: a leak under a sink might be a loose fitting, or it might be a corroded supply line that will fail again next month.
Once we know the problem, we explain your options in plain terms, including what it costs you to wait, and we give you a free estimate before larger work begins. We protect floors and finishes while we work, test everything before we leave, and clean up after ourselves. For remodels and new fixtures, we coordinate with your contractor or cabinet installer so rough-in happens at the right time and inspections go smoothly.
Why Carlson Duluth Company
Four generations of the Carlson family have worked in this trade. That history matters in a city where many houses are decades old and have been modified by several owners. Our plumbers have seen galvanized pipe, cast iron drains, lead service lines and every kind of past repair, and they know how to tie new work into old systems correctly.
We are also a full mechanical contractor. Because we install and repair boilers, furnaces, water heaters and gas piping as well as plumbing, one company can handle a project that touches several systems at once, such as a basement remodel that adds a bathroom and moves a water heater.
