Main Water Line Repair
Your main line is the whole house. Fix it right.
A failing main water line drops pressure everywhere, raises your water bill, and eventually fails completely. Wes finds the problem precisely and repairs it, trenchless where the pipe allows.
Signs your main line is failing
Low pressure everywhere is not a mystery.
When only one fixture has low pressure, the problem is usually local: a clogged aerator, a shutoff valve partly closed, or a bad supply line under that sink. When every fixture in the house is weak at the same time, the issue is upstream of all of them. The main water line runs from the city connection at the street to your home, and a leak or partial collapse anywhere along that run robs pressure from everything inside.
Other signs include unexplained spikes in your water bill, wet spots in the yard when it has not rained, soft or sunken ground along the line path, or discolored water at every tap. A patch of grass that stays green and grows faster than everything around it through a dry August is another one people miss for months.
Here is a check anybody can run before calling. Find the meter, usually in a pit near the curb or in the basement depending on the neighborhood. Shut off every fixture and appliance in the house, then watch the small sweep hand or the leak indicator triangle on the meter face. If it keeps turning with nothing running, water is moving somewhere it should not be. If the meter is still and the pressure is still bad, the trouble is more likely inside the house than under the yard.
The second check is where the water shows up. A break on the house side of the meter is your responsibility. A break on the street side is generally the water department’s. Wes reads which side of the meter the loss is on before anybody starts digging, because getting that wrong means excavating a yard for a repair the utility would have made. If the meter is still and the fixtures are weak, start with low water pressure solutions instead. Have him confirm it before a shovel goes in the ground.
- Low pressure at all fixtures
- Rising water bills without explanation
- Wet or sunken ground in the yard
- Grass greener along one line
- Discolored water systemwide
- Visible water at the street connection
- Meter turning with the house shut off
- Complete loss of water service
How we find the break
Targeted repair, not a guessing trench.
Wes uses pressure testing and acoustic listening equipment to locate the break before any digging happens. The goal is to open the ground only where the repair actually needs to go, not run a trench the full length of the line on a hunch. Locating equipment traces the path of the pipe first, because on older properties the service line does not always run where the paperwork says it does, and utility locates get marked before anything mechanical shows up.
The choice between trenching and boring comes down to what is on top of the line. An open trench is faster and cheaper to execute when the run crosses nothing but lawn. When the line passes under a mature tree, a driveway, a patio, or a retaining wall somebody paid real money for, boring a new line through and pulling it into place saves tearing all of that out and putting it back. Wes lays out both options with what each one actually involves on your property and lets you decide with the full picture.
Tree roots are the reason a lot of Front Range service lines fail. Roots do not drill through a healthy pipe, they find a joint or a corrosion pit that is already weeping and grow toward the moisture, then thicken and pry it open. Mature cottonwoods and silver maples in older Denver and Englewood neighborhoods are notorious for it. If the yard has a big tree sitting over the line, that gets factored into whether the repair is a spot fix or a reroute around it.
Winter changes the work. Frost depth on the Front Range means the ground over a service line can be frozen solid for the first couple of feet, and excavating through that is slower and harder on the surrounding landscape. Wes still does it, because a broken main is not a problem that waits for spring, but he tells you honestly what winter conditions do to the timeline and the yard restoration.

Material and code
Replaced right, built to last.
Older homes on the Front Range sometimes have original galvanized or even lead service lines still in place. We replace those with modern copper or PEX, properly sized for the home, installed to code, and permitted where required. As a licensed GC, Wes handles any landscaping or concrete restoration the excavation requires.
Galvanized service lines are the common one around here, and they fail from both directions. The zinc coating gives out, the steel underneath corrodes, and the same mineral scale that chokes the pressure inside the house builds up in the service run too. A galvanized line that has been in the ground since the fifties is on borrowed time regardless of whether it is leaking today. When Wes has one open for a spot repair he will tell you plainly what condition the rest of it is in, so you can decide between patching this break and replacing the run once. Patching a line that is about to fail somewhere else is not doing it right the first time.
Sizing matters as much as material. A three quarter inch service feeding a house that has grown a bathroom and an irrigation system since it was built will feel thin no matter how new the pipe is. When the line is coming out anyway, upsizing costs very little extra and fixes a flow complaint the homeowner has lived with for years. If a full new run is the right call, that is main water line installation.
After the repair, we pressure-test the full system before closing anything up, disinfect the new run where code calls for it, and confirm the flow at fixtures inside the house rather than just at the connection. You know the line holds before we leave. See our recent plumbing work.
Master plumber and licensed GC
Main line repairs done right from street to service.
The main water line repair involves coordination between your home, the city connection, and whatever is in between. As a master plumber and licensed GC, Wes pulls the required permits, coordinates with the water department when needed, and handles any surface restoration the excavation requires. One license, one point of contact.
That matters more on this job than most. A main line repair touches the yard, sometimes the driveway, occasionally the sidewalk, and it always touches the plumbing inside. When those pieces belong to three different companies, the homeowner ends up refereeing. Here they belong to one man who has to answer for all of it.
We serve Littleton and the entire Front Range, and the phone is answered around the clock because a broken main does not wait for business hours. Call (303) 883-9075 and we will come find the problem and tell you what the repair runs before we start.

Questions about main water line repair.
How do I know if my main water line is leaking?
Low pressure at every fixture, a water bill that climbed without a reason, or ground in the yard that is wet, sunken or unusually green over the line path. The quick home check is to shut off everything in the house and watch the meter. If the leak indicator keeps moving, water is going somewhere. Wes confirms it with a pressure test before any digging.
Is the leak my responsibility or the city’s?
Generally the run from the meter to the house is the homeowner’s and the street side belongs to the water department, though it varies by jurisdiction across the metro. That is the first thing Wes establishes, because excavating your yard for a repair the utility would have made is an expensive way to find out.
Can you repair the line without digging up the whole yard?
Usually. The break gets located acoustically first, so the excavation opens only where the repair goes rather than trenching the whole run on a hunch. Where the line passes under a driveway, a patio or a mature tree, boring a new line in and pulling it through avoids tearing out hardscape that costs more to replace than the plumbing.
Do you pull permits for this work?
Yes, where the jurisdiction requires them, and most do for service line work. Wes carries a master plumber license and a general contractor license, so permits, inspections and coordination with the water department are part of the job rather than something handed back to you to sort out.
How long does a main water line repair take?
Most spot repairs are a day. A full run replacement or a bore under hardscape can go two. Frozen ground in winter adds time to the excavation. You get the timeline before work starts, and if something underground turns out different than expected you hear about it that day, not at the end.
What material replaces an old galvanized service line?
Copper or PEX depending on the run, the soil and the sizing. Both are code approved and both will outlast galvanized by a wide margin. Wes explains why he is recommending one over the other for your situation rather than defaulting to whatever is on the truck.
My line runs under a big tree. Does that change things?
Often. Roots find an existing weep at a joint or corrosion pit and grow toward the moisture until they pry it open, and older cottonwoods and silver maples around the metro are repeat offenders. If the tree is staying, rerouting around it may make more sense than repairing in place and waiting for the same roots to come back.
Who fixes the yard, the concrete and the drywall afterward?
Wes does. That is the whole reason for holding both licenses. The excavation gets backfilled, compacted and graded, hardscape gets restored, and any interior work stays with the same person who did the plumbing. Nobody hands you a second contractor and a second schedule.
