Pipe Bursting Services in Boulder, CO
Pipe bursting is a trenchless technique where a new pipe is pulled through the path of the old, broken pipe, fracturing the old pipe outward at the same time. This method is very effective for complete pipe replacement, creating a new, durable pipe of the same or larger diameter. It's a robust solution for severely damaged or collapsed sewer and water lines, offering a long-term fix in Boulder, CO.
Main Water Line Repair in Boulder
Your main water line runs from the meter box to the house and is under constant pressure. When it leaks, you may notice a spinning meter dial with all fixtures off, low pressure or a wet spot that never dries. We locate the leak, expose the pipe and splice in a new section with approved fittings. If the line is old galvanized or polybutylene, we will recommend a full replacement before more breaks happen.
Underground Pipe Repair Cost Comparison in Boulder, CO
A single point repair on a shallow water line is the most economical option. Pipe bursting or pulling a new line through the old path costs more but avoids open trenching and long-term risk. Full trench replacement is sometimes needed when the old route is blocked or the pipe is too damaged. We explain each method and its cost so you can choose the best option.

Storm Drain and Lateral Repair in Boulder, CO

We inspect, clear and repair damaged storm drainage systems, ensuring proper water diversion and protecting your landscape and structures in Boulder, CO from water damage.

Galvanized and Polybutylene Line Replacement in Boulder
Galvanized steel pipe rusts from the inside, and polybutylene pipe becomes brittle and splits without warning. If your underground service is either material, repairs are usually temporary. We replace the line with PEX or Type K copper, often by pulling the new pipe through the old path to limit digging. A new line restores pressure and removes the risk of repeated leaks.
