Orangeburg and Cast Iron Sewer Replacement in Boulder
Some older homes still have Orangeburg pipe, a tar-paper material that flattens and blisters over time. Cast iron from the same era corrodes from the inside and scales up until little flow remains. When a camera shows widespread failure, patching is a waste of money. We replace the line in sections or end to end with PVC, and we can usually use trenchless methods to avoid tearing up the whole yard.

Trenchless Sewer Line Repair in Boulder, CO
For many sewer line issues, especially those caused by tree roots or pipe corrosion, trenchless repair offers a less invasive option. This method, which includes pipe bursting or pipe lining, requires minimal excavation, saving your yard and landscaping from major disruption. We use specialized equipment to either pull a new pipe through the old one or insert a resin-coated liner that cures in place, creating a new, durable pipe inside the old one. It's an efficient and popular choice for protecting property appearance in Boulder.
Sewer Line Leak Detection and Repair in Boulder, CO
Undetected sewer line leaks can lead to unpleasant odors, wet spots in your yard and even structural damage to your home's foundation.

Once identified, we provide targeted repairs, from patching small leaks to replacing compromised sections of pipe, ensuring a watertight system.
Sewer Vent Pipe Repair in Boulder, CO
While often overlooked, the sewer vent pipe is essential for proper drainage and preventing sewer gas buildup.

Cracked and Broken Pipe Repair in Boulder
Clay and cast iron sewer pipe crack from soil movement, heavy vehicles and simple age. A cracked section lets sewage leak into the soil and lets dirt fall into the pipe, which leads to recurring clogs. We excavate at the marked spot, cut out the damaged length and install new Schedule 40 PVC with shielded couplings rated for the transition. The repair is tested before we backfill so you know it holds.

Sewer Pipe Relining in Boulder, CO
Sewer pipe relining is a trenchless repair method where a new, durable pipe is created within the existing damaged one. A flexible, epoxy-impregnated liner is inserted into the old pipe and inflated, curing in place to form a seamless, strong and corrosion-resistant new pipe. This method is well suited for addressing cracks, minor breaks and root intrusion without extensive digging. It extends the life of your sewer system and is an great option for preserving landscapes in Boulder.
