Common questions about crawl spaces
- I had my crawl space encapsulated and outside vents sealed. Why have my radon levels gone up?
- I was told of an add-on for my crawl space encapsulation: insulation under the 20 mil white casing. Is that preferred?
- If a house already has a vapor barrier, is there a need for another one?
- If the humidity in your crawl space is 60-70% but in your house it’s lower, do you still need to fix the crawl space?
- Is a little water in a crawl space normal?
- Is a vapor barrier necessary under the subfloor?
- Is there a good ROI on crawlspace encapsulation?
- My home is on a crawl space; the problem is the $20k price tag. Is encapsulating a crawlspace worth the money?
- What are the potential disadvantages of having a crawl space under your house?
- What are the reasons for some houses having basements or crawl
- What are the top reasons for immediate house foundation repair and crawl space encapsulation?
- What challenges should I expect fixing squeaky floors in a house with a short crawl space?
South Duxbury: what the crawl-space inspection must decide
South Duxbury is a locality within Duxbury, not a single construction type. Do not assume the home has a crawl space or a particular water table. If it does, inspect whether moisture is arriving as vapor, as a plumbing leak, or as bulk water.
See Duxbury's zoning and flood-hazard maps for local context, then inspect this address. A dehumidifier alone may be insufficient when bare earth keeps supplying moisture or water repeatedly enters after rain. Fix the source, then consider whether a continuous barrier, drainage, and conditioning belong together. Check framing before covering it.
What a recent customer said

Gerald and his crew did an excellent job, first cleaning out all the debris and the dislodged insulation in the crawlspace. they were very communicative and understood my concerns and handled them professionally. When they were finished laying the sublayment and the top vinyl covering, carefully taping all the seams they put insulating foam around the perimeter, sealing the top of the vinyl. Gerald communicated two issues that were not part of the contract that I will subsequently take care of myself. Great job, very satisfied.
Frequently asked questions
Is South Duxbury different from the Town of Duxbury for flood maps?
South Duxbury is within Duxbury; use the town's current map and the specific address. A map does not diagnose crawl-space moisture.
Can I just add a dehumidifier?
Possibly, but first correct leaks and bulk water. If bare earth or air leakage continually supplies moisture, a dehumidifier alone may run without solving the source.
What does 603 need to inspect in a South Duxbury crawl space?
The first wet point, roof runoff, plumbing, exposed ground, existing drainage, humidity, and wood condition. The written plan should separate source correction, vapor control, and any structural or flood-risk work.
