What happens next
Tell us what you see, where the property is located and the best way to reach you.
We look at the affected area, foundation, drainage, sump and access needed to complete the repair.
Review the recommended work, materials, schedule, price and warranty before approving anything.
Local basement and foundation service
Spring snowmelt, heavy rain, frozen discharge lines, older stone foundations, finished basements and tight lots all affect the work. We plan the system for the house, the site and year-round Vermont conditions.
Vermont answer center
Start with a direct answer, follow the complete explanation and verify Vermont-specific claims against the linked primary source.
Handle electricity and contamination before anything else: do not enter standing water that may reach outlets, cords, a furnace, a water heater or the panel. Close a plumbing shutoff if that is the source. Photograph the high-water line, the first wet spot and the sump before cleaning, because that evidence disappears with the water. Wet porous materials generally need drying or removal within about one to two days.
Read the emergency first-steps guide →There is no single company that is best for every home. Compare the measured scope, drainage and discharge plan, sump equipment, structural responsibility, restoration, maintenance, warranty and total installed price. Homeowners here often weigh proposals from several regional companies, including Northern Basement Systems, Twin State Basements and 802 Waterproofing; judge the written scope in front of you rather than the name on it.
Compare Vermont basement companies →Yes. A separate inspection can show whether both proposals cover the same drainage length, pump and discharge work, structural components, demolition, restoration and warranty. The lower price is not automatically the better value when the scopes are different.

The place where water appears is not always where it begins. Use timing, location and exterior clues to make the first inspection more useful.
Read article →Waterproofing decisionsOne approach manages water after it reaches the foundation. The other works outside the wall. The right choice depends on more than price.
Read article →Cost planningA meaningful estimate begins with scope. Price ranges without the water path, foundation and access can mislead more than they help.
Read article →Foundation warning signsDirection is an important clue, but width, displacement, wall shape, foundation material and change over time determine the next step.
Read article →Foundation warning signsA bowed wall is a shape change, not just a crack. Measuring the movement and understanding the wall system come before choosing anchors, braces or rebuilding.
Read article →CrawlspacesA sealed liner is one layer. Bulk water, humidity, framing, combustion safety and radon testing still need their own answers.

We inspect the wet area, foundation, exterior grade, window wells, drains and sump system. Your estimate lists the recommended work, materials, discharge location, price and any finish work that is included.
It depends on the home. Exterior waterproofing is useful when the outside wall needs repair or excavation is practical. Interior drainage is often less disruptive and works well for groundwater and wall-floor seepage. We explain the advantages, limitations and cost of the options that fit your property.
Yes. Depending on condition, work may include compatible repointing, parging, block-joint repair, localized rebuilding, reinforcement, drainage and waterproofing. Loose, bulging or displaced walls need structural evaluation before a cosmetic coating is applied.
Horizontal cracks, stair-step cracks, widening cracks, visible displacement and cracks in a bowed wall should be inspected promptly. A stable vertical crack in poured concrete may only need a focused leak repair, but it still needs to be seen before the method is chosen.
Yes. We install and replace sump basins, primary pumps, secondary pumps, battery or water-powered backup systems, check valves, high-water alarms and exterior discharge piping.
