What the work involves
The actual scope, in the order it matters. If a step is missing from someone’s bid, ask them why.
- Remove the failed barrier, debris, and any fallen insulation that is holding moisture against the framing.
- Grade and clear the ground so the new barrier lies flat instead of tenting over rubble and trapping water underneath.
- Install new poly with overlapped and taped seams, sealed at piers and run up the stem wall where access allows.
- Take moisture readings on joists and subfloor before and after so there is a record of what the crawlspace was doing.
A barrier is ground cover and nothing else. It will not dry wood that is already wet, it will not remove growth that is already on the joists, and it will not stop water arriving from a leak or a rising water table. If the space stays humid with new poly correctly sealed down, the barrier was never the problem, and we will say that rather than sell you a second one.

What we see in McCall
Field notes on McCall: the housing stock, where the water comes from, and what that means for this work.
McCall's biggest single loss category is the unoccupied second home. A supply line lets go in January, nobody is in the building, and the call comes from a property manager or a neighbor days or weeks later. By then there is nothing left to extract. It is a structural drying and remediation job from the first hour.
Ten feet of snow a year is normal. Ice dams at the eaves push meltwater back under the roofing into the top plate and down the wall cavity, and snow sliding off steep metal roofs tears at vents, flashing and anything mounted on the wall below.
Short-term rentals are a large share of the housing around Payette Lake. Those jobs have to move because every day down is a cancelled booking, and the owner is usually out of state making decisions off photos and moisture logs.
Property managers and caretakers are the people who actually find the damage here. They're the ones who call, and they need to see progress on a job they're responsible for but not standing in.
It's a real drive up Highway 55 and 55 has weather closures and delays. We give McCall callers an honest arrival window and tell them what to do in the meantime rather than quoting a valley response time we can't hit.

Questions we get
Straight answers, including the ones that occasionally talk someone out of hiring us.
How do I know my vapor barrier has failed?
Look for plastic that is torn, bunched, missing in sections, or laid loose with wide gaps between sheets. Standing water on top of it, condensation on the underside of the subfloor, or a musty smell in the house are all signs it is not doing its job. Rusty duct straps and darkened joists are the later stage.
Will a new vapor barrier stop the musty smell upstairs?
Often, yes. Air moves from the crawlspace up into the living space through the stack effect, so crawlspace air is house air. Cutting ground moisture cuts the source of that smell. If the smell persists after the barrier is replaced, the moisture is coming from somewhere else and there is likely existing growth to remediate.
Do I need full encapsulation instead?
Not necessarily. If the crawlspace is dry apart from ground evaporation and the vents are working, a properly installed barrier is the correct and much cheaper fix. Encapsulation is warranted when the space stays humid with a good barrier in place, when there is repeat mold growth, or when there is standing water that needs drainage.
