Water heater and gas line repair in Frogtown, Saint Paul, MN 55104
Frogtown packs small homes and duplexes onto narrow lots between University Avenue and the rail yards, and their basements leave very little room for a water heater swap.
The short answer
Frogtown is a dense neighborhood of 1880s to 1920s homes and duplexes near University Avenue and the Green Line. Our usual calls here are water heaters in cramped basements, gas line leaks and repairs, old galvanized supply pipe and frozen lines on exterior walls. We work carefully in tight spaces, and our phone is answered 24/7.
Swapping water heaters in tight Frogtown basements
Many Frogtown homes have low ceilings, narrow stairs and a basement shared by a furnace, water heater and laundry in a small space. Getting an old tank out and a new one in takes planning. Sometimes a shorter, wider tank fits better, and the venting has to be adjusted to match.
We measure first, check the vent and gas connection and confirm there's enough clearance around the burner. We bring a heater sized for both your household and your stairs, pull the permit and haul the old tank away. For small duplexes, separate heaters for each unit can end arguments over hot water.

What to do if you smell gas in a Frogtown home
Older gas piping in Frogtown homes often runs through basements and tight crawl spaces, with fittings that have been there for decades. A loose joint or corroded section can leak. If you smell gas, leave the house right away, don't flip switches and call Xcel Energy or 911 from outside.
Once it's safe, we find the leak with a gas detector and pressure test, then repair or replace the damaged section. We also check appliance connectors, which can crack over time. For new gas lines to a range or dryer, we size the pipe, add shutoffs and test before turning anything on.
Old pipes and cold walls along University Avenue
Galvanized supply pipe is still common in Frogtown, and low water pressure or rusty water often means it's time to replace it. Many homes also have kitchens or bathrooms on exterior walls with little insulation, and those pipes freeze when the cold settles in for a few days.
We replace corroded pipe with copper or PEX and reroute lines away from cold walls where we can. We also check main shutoffs and replace them if they're stuck. With the Green Line running along University, we're often nearby. Call (651) 215-2087 and tell us what's going on.

Plumbing questions from Frogtown
Can a new water heater fit down my narrow Frogtown basement stairs?
Usually, yes. We measure the stairs, door and space before choosing a heater. In tight Frogtown basements, a shorter, wider model or a tankless unit may fit better. We plan the move so we don't damage walls or railings.
Who should I call first if I smell gas in my Frogtown house?
Leave the house, avoid switches or flames and call Xcel Energy or 911 from outside. After they make it safe, call us to find and repair the leak. We pressure test the line and check appliance connectors before anything is relit.
How do I know if my Frogtown home has galvanized pipes?
Look at the pipes near your water meter. Galvanized steel is dull gray with threaded fittings, and a magnet will stick. If you have low pressure or rusty water, the pipes may be narrowing inside. We can check and explain replacement options.
