Crawlspaces that stay dry and out of the way
Most Oregon homes have a crawlspace, and most of them are doing the opposite of what they should: leaking warm (or cold) air, collecting moisture, and quietly raising your energy bill. We insulate and seal crawlspaces so they stop being a problem and start being a feature.
What this means for your home
Most Oregon homes have a crawlspace, and most of them are doing the opposite of what they should: leaking warm (or cold) air, collecting moisture, and quietly raising your energy bill. We insulate and seal crawlspaces so they stop being a problem and start being a feature.
- Rigid foam board on the foundation walls to break the thermal bridge
- Sealing of the rim joist and perimeter gaps — where most of the leakage is
- Vapor barrier work on the slab when it makes sense for the space
- Checking for standing water and drainage issues before we insulate, not after
- Honest answer about whether the crawlspace should be conditioned or ventilated for your house
Why TCS
“Insulation only works if it’s installed for the way your house actually holds air.”
We look at air leaks first, moisture second, and insulation depth third. That’s why a TCS install stays comfortable and energy-efficient.
Salem-area homes
Crawlspaces are all over the Valley, we work on them regularly.
Water first, foam second
We won’t insulate over a drainage problem. Not ever.

How we work
The TCS process, start to finish
We get a look in there first
Crawlspaces are all different. One with active drainage issues needs a different plan than one that’s already mostly dry. We inspect before we quote, so the estimate is for what your crawlspace actually looks like — not a catalog.
We fix the water story first
If there’s standing water, we don’t just build a wall of foam over it. We address drainage and the source of moisture, then insulate. That order matters and is why crawlspaces don’t usually fail on the insulation.
We install the foam, seal the perimeter
Foundation-wall foam board, rim joist sealing, and any perimeter gaps we find. The whole job is about getting the crawlspace outside the conditioned envelope of the house, or into it cleanly — whichever fits your setup.
We walk you through it

Good to know
Questions people ask before booking
Most modern guidance says a sealed, insulated crawlspace outperforms a vented one in our climate, especially if there are moisture issues or cold-floor complaints. But your specific house might still benefit from venting if it has good drainage and no moisture history. We’ll tell you which one based on what we see in there — not a default position.
Yes — most of the time. The droppings and smell usually come from a leaking perimeter letting air and pests in. Sealing and insulating the crawlspace (after cleanup) fixes the root cause. We’ll be upfront about how much cleanup is needed and who should do it before we book the insulation work.
Sometimes. If the existing barrier is torn, missing in patches, or there’s standing water that’s wicking up, a new one can matter. If the slab is already in good shape and dry, we usually skip it. We’ll look first.
If your ground-floor or upstairs-over-crawlspace rooms feel noticeably colder and you can see condensation or hear drafts under the floor, that’s a good sign the crawlspace is leaking air. A quick inspection settles it — most people have a hunch but have never actually looked in there since they bought the house.
