Grand Rapids, MI crawl space guide
Crawl space waterproofing in Grand Rapids, MI
Waterproofing deals with liquid water getting in: grading, gutters, drain tile, and a sump. Encapsulation seals the crawl against ground moisture and humid air. A crawl that takes on water usually needs the water handled first, then the encapsulation.
GR Crawl Space is an independent directory and referral site, not a contractor. We do not waterproof crawl spaces.
Signs of water vs. humidity
Liquid water and humid air are different problems. Waterproofing is the liquid-water job. Encapsulation and a dehumidifier are how a closed crawl deals with ground moisture and humid air.
Liquid water
- Standing water, or a floor that stays wet after rain
Humidity
- Musty smell upstairs that tracks with humid weeks
- Condensation on windows, walls, or pipes (U.S. EPA)
- Relative humidity regularly above 60 percent. That is the EPA ceiling; it suggests 30 to 50 percent as ideal (U.S. EPA).
Winter dryness can hide summer humidity. Measure relative humidity in summer with an inexpensive meter (U.S. EPA).
What waterproofing includes
Waterproofing deals with liquid water getting in: grading, gutters, drain tile, and a sump. Get this scoped separately on the quote.
If water stands on the floor, "the source will need to be identified and corrected and the standing water removed" before sealing (DOE crawl space guide).
How it changes an encapsulation quote
A crawl that takes on water usually needs the water handled first, then the encapsulation. ENERGY STAR and DOE both treat water and humidity control as part of sealing a crawl (ENERGY STAR, DOE Building America). Get the water fix scoped separately on the quote, then compare the seal on the encapsulation cost guide. Those published ranges are for encapsulation, not for grading, gutters, drain tile, or a sump.
Michigan cost
Ranges vary; get two written quotes. This page does not print a Michigan waterproofing total. The published guides cited on the cost page price encapsulation scopes. They do not price grading, gutters, drain tile, or a sump on their own. A contractor's site visit sets the real number.
