Before you book crawlspace vapor barrier & encapsulation
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph the crawlspace safely
Shine a light from the access and take photos of the soil, walls, framing and insulation. Do not enter if you see standing water, mold or exposed wiring.
Check for water after rain
Look at the crawlspace or foundation after heavy rain for pooling or damp soil. Water sources must be fixed before sealing.
Fix gutters and grading
Make sure downspouts discharge away from the house and soil slopes away. This is often the simplest moisture fix.
Tell the pro what lives in there
Mention furnaces, water heaters, ducts and any signs of pests so the plan accounts for combustion air, access and treatment.
Clear the access
Clear stored items from near the crawlspace opening so the pro can bring in liner rolls and equipment.
Ask about humidity control and radon
Ask what controls humidity after sealing, who maintains it, and whether radon testing is recommended for your area.
Say where in Foster City you are
Add your neighborhood, for example Isle Cove, Carmel Village, and Treasure Isle, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.
