Our Services

We handle the specific moisture problems that plague Hillsboro homes and older builds near the Oregon Health & Science University campus and beyond.

Foundation Waterproofing

Cracked, weeping, or bowing foundation walls leak water into basements. We install interior perimeter drains and sump pumps, or exterior coatings and drain systems. West Hillsboro and Tanasbourne homes often need both approaches for complete protection.

Crawlspace Vapor Barrier Installation

Crawlspaces under Orenco Station and downtown Hillsboro properties trap moisture that rots wood and spreads mold. We install heavy-duty plastic barriers, seal rim joists, and add dehumidifiers to keep relative humidity below 55 percent.

Frequently Asked Questions

How long does crawlspace vapor barrier installation take?

Most crawlspace barrier jobs take 1-3 days depending on size and drainage complexity. We work fast without cutting corners.

Will I need a permit for foundation waterproofing in Hillsboro?

Most interior drain and sump pump work doesn't require permits. Exterior work and structural repairs do. We handle all permit paperwork and inspections for you.

What causes water problems in Hillsboro crawlspaces?

Heavy winter rain, high water tables, and poor original drainage send groundwater into crawlspaces. Inadequate or failed vapor barriers trap moisture. New encapsulation stops both sources.

Can I use my basement or crawlspace while work is happening?

We'll discuss work zones and access with you before starting. Most projects allow limited access. Heavy installation days may require you to avoid certain areas for safety.

Do you service older homes near Orenco Station and downtown?

Yes. Older Hillsboro homes often have weak or failed original waterproofing. We specialize in bringing them up to modern standards without damaging historic elements.

What's included in your warranty?

Our warranty covers all materials and labor for a set period. We stand behind every job. Details are in your estimate and contract.
