Basement waterproofing & drainage
Waterproofing, drains, sump systems and exterior work for leaks, seepage and recurring wet floors.
Serving Greater Burlington & northwestern Vermont
Basement waterproofing and foundation repair in Greater Burlington.
Basement waterproofing and foundation repair across Greater Burlington and northwestern Vermont, covering three problem areas that are often connected but need different fixes: waterproofing and drainage for leaks, seepage and recurring wet floors; foundation and structural repair for cracked, bowed, settling and deteriorated foundations, including masonry and structural stabilization; and crawlspace and moisture control for damp or damaged crawlspaces, from vapor barriers and dehumidification to structural repairs. A wet floor after rain is usually a drainage problem, interior drainage, sump systems, crack repair, exterior waterproofing, grading and downspout work, while a cracked wall or floor gets evaluated for whether it is a simple seal or a structural issue before any repair is recommended. Guessing is not part of the process. Requests are routed to a Vermont contractor suited to the specific property and problem, starting from an inspection instead.

There is water in my basement right now: what should I do first?
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 scene before cleanup. The high-water line, the first wet spot and the sump all disappear once cleanup starts. Wet porous materials generally need drying or removal within about one to two days.
Read the emergency first-steps guide →Which basement waterproofing company is best in Vermont?
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. That is true here too. Homeowners 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. The name on it matters less.
Compare Vermont basement companies →Can I get another estimate after Northern Basement Systems, Twin State or 802 Waterproofing?
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.

Water diagnosis
Why Is Water Coming Into My Basement After Rain or Snowmelt?
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 decisionsInterior Drainage vs. Exterior Waterproofing: What Is the Difference?
One 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 planningWhat Affects Basement Waterproofing Cost in Vermont?
A meaningful estimate begins with scope. Price ranges without the water path, foundation and access can mislead more than they help.

Direction is an important clue, but width, displacement, wall shape, foundation material and change over time determine the next step.

A 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.

See all FAQsWhat basement and foundation services do you provide?
The work covers basement waterproofing, interior drainage, exterior foundation waterproofing, sump pumps and backup systems, crack repair, bowing-wall stabilization, settlement and pier repair, stone and block foundations, crawlspace encapsulation and structural repair, window wells, grading, drainage, dehumidification and moisture-control projects.
How do you determine the right basement waterproofing repair?
An inspection covers 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.
Is interior drainage or exterior waterproofing better?
The answer 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. Advantages, limitations and cost get explained for whichever option fits your property.
Can you repair old stone and block foundations?
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.
What foundation cracks should be inspected quickly?
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.
Do you install sump pumps with battery backup?
Yes. Sump basins, primary pumps, secondary pumps, battery or water-powered backup systems, check valves, high-water alarms and exterior discharge piping are all part of what gets installed and replaced.
What towns do you serve?
Service covers Burlington, South Burlington, Winooski, Colchester, Essex, Essex Junction, Williston, Shelburne, Charlotte, Hinesburg, Milton, Richmond, Westford, Jericho, Underhill, Cambridge, Jeffersonville and Fairfax, plus nearby properties depending on the work required.
What happens after I request an inspection?
Contact comes first: about the property, the work needed and scheduling. After the inspection, you receive the recommended scope and price before deciding whether to move forward.
