Greater Burlington & northwestern Vermont

Basement and foundation service areas: local waterproofing and repair

We serve Burlington and the surrounding Champlain Valley with basement waterproofing, foundation repair, crawlspace, sump pump, grading and drainage service.

What is under these towns

The ground and the air in a Greater Burlington basement

Across the Burlington area, finer sediments such as sand, silt and clay lie over glacial till, laid down by ancient glacial-lake and Champlain Sea waters. That matters below grade. Till produces rocky, dense, poorly drained soils, while the sandy deposits over it are easily excavated and drain well. A single street can cross both, which is one reason two neighboring basements in the same town can need different drainage. (UVM PLACE Program, Burlington surficial geology)

Radon is the other thing every one of these basements shares. The Vermont Department of Health reports that one in seven Vermont homes has elevated radon, sets the action level at 4.0 pCi/L, and advises retesting every five years or whenever significant changes are made to a home's structure or mechanical systems. Waterproofing and crawlspace work count as such changes, and for a basement that will be lived in, the Health Department says short-term testing may be done there.

Choosing a registered contractor in any of these towns

Vermont requires residential contractors to register with the Secretary of State's Office of Professional Regulation for any residential construction valued at $10,000 or more, including labor and materials. Registration carries a written-contract attestation, where contracts must include the price, work dates, scope of work and a change order provision, and proof of liability insurance of at least $1,000,000 per occurrence and $2,000,000 aggregate.

That standard applies in every town listed here, from Burlington to Fairfax. Ask any company for its registration, ask for the insurance certificate directly from the insurer, and check that the contract you are handed names all four required items.

Local conditions vary within the region. The table below lists the first thing each town's inspection tends to look at, from access around close-set homes to long discharge routes and older masonry. Use it as a starting point, not a diagnosis, and open the town page for the local detail. The two-level structure, core and extended, describes how quickly a visit can usually be arranged and not the quality of the work.
