Whole-home repiping in Longmont, CO comes up when a house's interior supply lines, not the sewer lateral or a single fixture, have reached the point where individual repairs no longer make sense. This is different from a single pipe repair: repiping replaces the supply lines running through the walls and under floors that bring water to every fixture in the house. It's usually needed because the existing material (galvanized steel or, in some homes, early plastic piping types no longer used) has reached the end of its practical service life.
Signs a Home May Need Repiping
- Multiple pinhole leaks appearing in different locations over a short period, rather than one isolated leak
- Consistently low water pressure throughout the house that isn't explained by a single clogged fixture or valve
- Discolored (rusty or brownish) water coming from multiple fixtures, especially right after the water's been off
- Visible corrosion on any exposed supply piping in a basement or crawlspace
- A home with original galvanized steel supply lines, common in Longmont's East Side and West Side Historic District homes built before mid-century
One pinhole leak on its own doesn't necessarily mean the whole house needs repiping; it might be an isolated failure. Multiple leaks appearing in different spots over months, though, usually means the pipe material itself is failing broadly, and patching each new leak as it appears becomes more expensive over time than addressing the whole system at once.
What "Repiping" Actually Means Here
Repiping replaces interior supply lines, which is different from the sewer lateral (drain, not supply) and different from the service line bringing water from the street to the house. See water line repair and replacement if the actual issue is the incoming service line rather than the plumbing inside the house. Confusing these two is a common mix-up, since both can cause similar symptoms like low pressure, but they're different pipes with different repair scopes.
Material Options
Modern repiping typically uses copper or PEX (cross-linked polyethylene). Copper has a long track record and is rigid, requiring more fittings to route around corners. PEX is flexible, generally faster to install with fewer joints, and has become the more common choice for whole-home repiping in recent years, though the right choice depends on the specific home's layout and any local code preferences.
What a Repiping Project Involves
- Mapping the existing supply line routing throughout the house
- Opening limited sections of wall or ceiling to access and route new lines, with an emphasis on minimizing unnecessary demolition
- Running new supply lines to every fixture, then pressure-testing before closing up any opened sections
- Patching and restoring opened wall or ceiling sections (drywall repair is often coordinated separately from the plumbing work itself)
- Final inspection under Colorado's plumbing code before the project is considered complete
Repiping vs. Patching Individual Leaks
Patching each new leak as it appears in an aging galvanized system feels less disruptive in the moment, but it's a pattern that tends to repeat: once one section of pipe starts failing from age or corrosion, nearby sections of the same age and material are often not far behind. A full repiping project is a larger undertaking upfront, but it ends the pattern of recurring emergency leaks rather than managing them one at a time indefinitely.
What Affects the Cost
Home size and number of fixtures
More fixtures and a larger home mean more line runs and more labor.
Material choice
Copper generally costs more in materials than PEX, though labor time can offset some of that difference.
Access and wall construction
Plaster walls in older historic-district homes are typically more labor-intensive to open and patch than drywall.
Number of stories
A multi-story home with vertical runs adds complexity compared to a single-level layout.
Drywall/finish restoration
Patching and finishing opened sections is sometimes quoted separately from the plumbing work itself.
These factors give you the shape of the cost, but your specific situation is what actually sets the price. Call (213) 635-0350 for a straight answer.
Frequently Asked Questions
A single, isolated leak doesn't necessarily mean the whole system needs replacing. Multiple leaks appearing in different spots over weeks or months, especially in an older home with galvanized pipe, is the pattern that usually points toward repiping rather than continuing to patch individual failures.
No, these are different pipes entirely. Repiping addresses interior supply lines that bring water to fixtures throughout the house. The sewer line carries waste out, and the water line brings water in from the street, both separate systems with their own repair processes.
Both are used in modern repiping. Copper has a long track record and is rigid; PEX is flexible, generally faster to install with fewer joints, and has become more common in recent years. The right choice depends on your home's layout and specific circumstances.
A well-planned repiping project targets limited, specific sections of wall or ceiling rather than opening up the entire house. The goal is accessing what's needed to route new lines while minimizing unnecessary drywall and finish work to repair afterward.
Yes, call and describe what you're experiencing (recurring leaks, low pressure, discolored water) and we can talk through whether repiping is actually the right scope for your situation.
