If you require exterior basement waterproofing in Helena, Three Brothers Waterproofing is the go-to team across Lewis and Clark County.

Exterior basement waterproofing involves creating a protective barrier on the outside of your foundation to keep water out. This typically includes removing soil around the foundation, applying waterproof membranes, and installing proper drainage systems to redirect water away from your home. Given Montana's semi-arid highland, it is crucial to tackle these issues to prevent long-term damage and ensure your home's safety and durability.

Our process begins with careful excavation around the foundation, allowing our team to assess any potential vulnerabilities. After thoroughly cleaning the foundation walls, we apply high-quality waterproofing membranes that prevent moisture infiltration. Additionally, we will install drainage systems, such as French drains, that guide water away from your home, mitigating the risk of flooding, especially during heavy rains.

We provide upfront flat-rate written quotes, so you know exactly what to expect without any hidden costs. With a workmanship guarantee backing our services, your investment is secure. Exterior basement waterproofing typically ranges from $225-$600, giving you peace of mind while protecting your home.
