Post-Tension Slab Leak Repair in Longmont
Many newer homes are built on post-tension slabs with steel cables under high tension. Cutting into these slabs requires care and scanning to avoid hitting a cable. We use ground-penetrating radar or other scanning methods before opening the floor. When risk is too high, rerouting the plumbing is usually the safer option.

Direct Foundation Leak Repair in Longmont, CO
When the leak is in an accessible spot and the rest of the pipe is in good condition, direct repair is often the most economical choice.

Flooring can then be restored by your flooring contractor.
Exterior Foundation Leak Solutions in Longmont
Many foundation leaks start from exterior factors like poor drainage, overflowing gutters, or saturated soil. We assess your home's exterior to identify these culprits.

Frequently Asked Questions About Foundation Leak Repair in Longmont
Leak detection usually costs $150 to $450. Direct repairs through concrete usually range from $1,500 to $4,000, and reroutes often run $1,800 to $5,000 depending on length and access. Full repipes cost more and are quoted individually.
While not always preventable, regular plumbing inspections can help catch potential weaknesses. Keeping soil moisture consistent around your foundation, addressing drainage issues, and ensuring proper pipe installation during new construction or remodels can help reduce the risk of future foundation leaks in your Longmont, CO home.
You can check your water meter with all fixtures off to confirm a leak. Locating the exact spot under a foundation takes specialized equipment and training.

While some very minor surface cracks might be sealed with DIY products, most foundation leaks, especially those involving plumbing or structural integrity, require professional expertise. Improper repairs can lead to greater damage, costly future fixes, and may not comply with local building codes. It is always best to consult with a professional.
