What We Handle

Plumbing Services in Boulder

Front Range homes bring a specific mix of problems. Expansive clay soils shift foundations and slabs. Older Boulder housing stock still has galvanized supply lines in the walls. Hard freeze-thaw winters split exposed, uninsulated pipe every year. Boulder Express Plumbing is built around that reality, not a generic national script.

Water Heater Repair & Replacement

Same-day diagnosis for tank and tankless units at Boulder's altitude, where combustion and venting requirements differ from sea-level installs.

Frozen & Burst Pipe Repair

Boulder's hard freeze-thaw cycles split exposed and uninsulated lines, so emergency shutoff and repair are, day or night.

Boiler Repair

Boulder's older housing stock still runs a lot of hydronic heat, so boiler diagnosis and repair go alongside standard plumbing work.

While You Wait

What to Do Before We Arrive

A few safe, simple steps can limit damage in the minutes before a technician gets to you.

Shut Off the WaterIf a pipe has burst or a fixture is actively leaking, find your main water shutoff valve (often in the basement, a utility closet, or near the water meter) and turn it fully clockwise.
Cut Power Near Standing WaterIf water is pooling near outlets, panels, or plugged-in appliances, shut off power to that area at the breaker rather than reaching into the water yourself.
Never Use Open Flame on Frozen PipesA torch or open flame on a frozen line is a real fire risk. Space heaters aimed nearby, or simply calling us, are the safer route.
Photograph the DamageBefore you start moving anything, take a few photos or a short video. It makes any insurance claim easier and gives our technician useful context before they even arrive.
Local Conditions

Why Boulder Plumbing Is Different

Expansive Clay Soil

Much of Boulder sits on claystone and bentonitic soils that swell when wet and shrink when dry. That movement is a leading cause of slab leaks and cracked sewer laterals in older parts of the city, and it's why we diagnose before recommending any concrete work.

High-Altitude Water Heaters

At roughly 5,430 feet, combustion and venting requirements for gas water heaters and boilers differ from sea-level installs. An improperly vented unit at altitude is a real safety issue, not just a performance one.

Freeze-Thaw Winters

Boulder's freeze-thaw cycles put real stress on exposed and uninsulated supply lines, especially in crawlspaces and older additions. Frozen and burst pipe calls spike every winter, usually after a hard overnight cold snap.

Older Housing Stock

Neighborhoods like Mapleton Hill and parts of University Hill still have homes built before 1950, some with original galvanized supply lines or clay sewer laterals nearing the end of their service life.

Common Questions

Boulder Plumbing FAQ

Do you offer emergency plumbing after hours in Boulder?

Yes. Our line is answered 24/7, including nights, weekends, and holidays, and a licensed technician is dispatched for genuine emergencies like burst pipes, sewage backups, or a complete loss of hot water.

Why does Boulder see more slab leaks than other Front Range cities?

It's largely soil, not pipe quality. Boulder's expansive clay and claystone shift with moisture changes, putting uneven pressure on slab plumbing over years. See our slab leak detection page for how we locate a leak before any concrete is cut.

Are plumbers in Colorado licensed at the state or county level?

Statewide. Colorado plumbing licensing runs through the state's Department of Regulatory Agencies (DORA), not a Boulder County-specific system, so the same licensing standard applies whether the job is in Boulder, Golden, or Parker.

Do you charge extra for nights or weekends?

We quote a price before any work begins, and that price reflects the job itself. Ask about current after-hours terms when you call. We'd rather be upfront on the phone than surprise you on an invoice.
