Ground covers, wall liners and drainage that keep moisture from rising into the house, installed with taped seams and sealed edges.
Moisture rises from the ground into the air above it every day, even when the soil looks dry. In a crawl space, that vapor reaches wood framing and insulation, and in a basement, it creates damp air and a musty smell.
A vapor barrier is a thick plastic sheet that stops that flow. The material and the installation both matter: heavier, reinforced liners last longer, and seams, edges and penetrations must be sealed so the barrier works as a system and not as loose sheets.
Thin plastic tears and shifts. Reinforced liners resist punctures and foot traffic, and they last many years. We choose a thickness suited to how the space is used.
A barrier with open seams is only a partial cover. We overlap and tape seams, seal to the walls and piers and cut neat openings around posts and pipes.
A vapor barrier does not stop liquid water. If the space gets wet, we recommend a drain, a sump pump or exterior grading work to remove the source.
On walls, a liner extends the barrier up the foundation. It works with insulation and sealing to turn the space into a controlled environment.

You tell us what is going on, which rooms bother you and what you hope to change, and we set a time that fits your day.
We walk the attic, walls, crawl space and equipment, measure depths and use thermal imaging when it helps.
We protect the house, seal air leaks, place baffles and fix small problems so the insulation can do its job.
Loose-fill, batts, foam or board goes in to the planned depth, with clean edges and clear markers.
We measure the result, take photos and test air leakage when the scope includes it.
We walk the finished work with you, answer questions and leave the site clean.
Thin sheets often tear and leave open seams. A reinforced, sealed liner performs far better.
No. Water from outside needs drainage. We assess the source and recommend a proper fix.
If water comes from the sides or above, a barrier can hide it. That is why we find the source before we cover the ground.
A good liner lasts many years when walked on carefully. We advise how to protect it.
A slab has its own vapor protection from construction. We check for leaks and recommend fixes only if needed.
