Finished crawlspace encapsulation with heavy-duty vapor barrier on the ground and walls, wrapped piers and post supports — Portland, Oregon
A sealed, dry crawlspace: heavy-duty liner on the ground and walls, wrapped piers, and supported framing.
What's Under Your Floor

Most Older Portland Homes Have the Same Three Problems Down There.

Homes built before about 1980 often just sit on the foundation with nothing holding them down. Add Portland's wet season and a vapor barrier that tore or went missing decades ago, and you end up with a house that can slide in an earthquake and pulls damp air up through the floor.

If any of these sound familiar, your crawlspace is telling you something:

  • Floors are cold in the winter, even with the heat on
  • A musty or damp smell comes up into the house
  • Mice, rats or droppings in the crawlspace
  • Insulation is sagging, falling down or missing
  • The ground under the house is bare dirt, or the plastic is torn
  • You can't see anchor bolts on top of the foundation wall
  • A home inspector flagged the crawlspace or the foundation
Cross-section of a Safe & Dry crawlspace The floor framing sits on a cripple wall and sill plate. Anchor bolts tie the sill plate to the concrete foundation, plywood braces the cripple wall, insulation fills the floor joists, and a sealed vapor barrier covers the soil.

Who This Is For

Built for Three Kinds of Owners.

Homeowners

You own an older home in Portland, Gresham or the east side and want to stop worrying about the big one, the damp smell and the cold floors.

Home Sellers

The buyer's inspector flagged the crawlspace or foundation. We fix it fast and give you photos and permit records, so it doesn't become a repair credit at closing.

Landlords & Property Managers

Protect the building, cut down on tenant complaints about cold floors and pests, and have documentation on file. Ask about multi-property pricing.

Common Questions

Crawlspace Repair & Earthquake Retrofit FAQ.

How much does an earthquake retrofit cost in Portland?
A standard bolt-and-brace retrofit (Quake-Ready) starts at $4,995 for a typical home. Safe & Dry, which adds a vapor barrier, floor insulation and air sealing, starts at $11,995. After the free inspection you get an exact fixed price in writing.
Do I need a permit?
Yes, earthquake retrofit work needs a building permit. Most one- and two-family homes up to three stories with a continuous concrete foundation qualify for the City of Portland's prescriptive plan, so no engineer is needed. We handle the paperwork and meet the inspector. Homes on steep slopes may need an engineer, and we'll tell you at the inspection.
How long does it take? Do I have to leave?
Quake-Ready takes 1–2 days, Safe & Dry takes 2–3, and Total Crawlspace Shield takes 3–4. We work from the crawlspace access, so you can stay home, work from home, and keep your pets inside.
Are there rebates?
Sometimes. Energy Trust of Oregon and City of Portland programs offer incentives for floor insulation and air sealing on qualifying homes. Program rules change, and some incentives require a participating contractor, so we'll tell you up front what your home may qualify for.
Will it lower my energy bills?
A lot of an older home's heat escapes through an uninsulated floor and air leaks into the crawlspace. Insulating and air sealing the floor usually makes rooms feel warmer and cuts heating waste. Savings depend on your home and heating system.
I'm selling. Is it worth doing before I list?
Often, yes. Buyers' inspectors regularly flag unbolted foundations and wet crawlspaces, and that usually turns into a repair credit or a lower offer. Fixing it first, with photos and permit records in hand, keeps you in control of the number.
What is crawlspace encapsulation?
Encapsulation seals the crawlspace off from outside air and ground moisture: a heavy-duty liner covers the soil and foundation walls, the vents are sealed, and a dehumidifier keeps humidity in check. It is the most complete fix for wet or musty crawlspaces and is included in our Total Crawlspace Shield package.
How do I know if my house is bolted to the foundation?
Look at the top of the concrete foundation wall from inside the crawlspace. If you see anchor bolts with nuts and washers every few feet holding the wood sill plate down, it is bolted. Many Portland homes built before about 1980 have none. Our free inspection checks every wall and shows you photos.
What areas do you serve for crawlspace repair?
Portland (all quadrants), Gresham, Troutdale, Milwaukie, Happy Valley, Beaverton, Tigard, Lake Oswego, Oregon City, Sandy and the rest of the Portland metro. Our shop is on SE 177th Ave on the Portland–Gresham line.
Do you work on rentals?
Yes. We work with landlords and property managers across Portland and Gresham, and we can schedule around tenants. Ask about pricing for multiple properties.
