Interior perimeter drainage
A channel at or below the slab edge collects water from the wall-floor area and routes it to a sump or gravity outlet. Design details matter in finished basements and around footings.
Wet basement service · Greater Burlington
We fix basement leaks, wet floors and damp walls with interior drainage, exterior waterproofing, sump systems, crack repair, grading and humidity control.
Common reasons homeowners call
Water at the wall-floor joint after rain or snowmelt
Damp or darkened concrete, block or stone walls
Efflorescence or flaking finishes on masonry
Wet carpet, flooring or baseboards along exterior walls
Recurring puddles near a window well, bulkhead or utility penetration
A musty basement that remains humid despite ordinary dehumidification
An existing interior drain that backs up or no longer keeps up
Repairs and systems
Depending on the property, the project may use one of these repairs or combine several into a complete system.
A channel at or below the slab edge collects water from the wall-floor area and routes it to a sump or gravity outlet. Design details matter in finished basements and around footings.
Where access and conditions support it, exterior work can expose the foundation, address deterioration, add a waterproofing or drainage layer and improve footing-level drainage.
A localized leak through poured concrete, a pipe penetration or a cold joint may have a focused repair path. Block, stone and moving cracks require different evaluation.
Covers, drains, grading and discharge changes may be appropriate where water is concentrated at a basement window, stairwell or bulkhead.
Pump capacity, pit design, check valves, backup power, alarms and a discharge route that stays clear in winter are part of the water-control system.
A dehumidifier or vapor-management layer may control moisture that is not arriving as liquid water, but it should not be used to disguise an unresolved leak.
At your property
We look at the affected area, the foundation, exterior conditions, existing equipment and access so the estimate covers the complete job.
Request an inspectionWhere water first appears and how far it travels
Whether the event follows rain, thaw, plumbing use or a power outage
Foundation type and visible crack, joint or penetration conditions
Exterior grade, gutters, downspouts, low areas and window wells
Existing drains, sump pit, pumps, backup and discharge termination
Finished walls, flooring, utilities and access that affect the work
Whether plumbing, sewage, restoration, mold or structural specialists are also needed
Your estimate
Interior drainage manages water after it reaches the foundation; exterior work is intended to intercept, drain or block it before entry. Neither is automatically the universal answer.
Stone, block and poured concrete handle water and repair methods differently. Mortar, cores, cracks, joints and wall condition change the options.
Flooring, drywall, built-ins and utilities can affect access, demolition and restoration. The proposal should state what is included.
Exterior discharge can freeze or become buried. The inspection should address slope, termination, backup and how the system works during cold weather.
Already have an estimate?
If Northern Basement Systems, Twin State Basements, 802 Waterproofing or another company has already inspected the property, request a separate estimate and compare quantities, materials, restoration, maintenance, warranty and price.
Common questions
These answers cover the questions homeowners ask most often. Your inspection and written estimate will address the conditions at your home.
Coatings may help with limited moisture moving through sound masonry, but they do not correct water pressure, an open crack, a leaking wall-floor joint, a failed drain or poor exterior drainage. Repeated blistering or peeling is a reason to investigate the source instead of adding another coat.
A localized crack or sump replacement can be much shorter than a full perimeter system or exterior excavation. Access, linear footage, demolition, foundation condition, drainage and restoration all affect timing. A written proposal should separate installation time from curing, inspection and finish restoration.
Reducing water and humidity removes conditions that allow mold to grow, but waterproofing is not a mold diagnosis or remediation service. Existing suspected growth, contaminated materials or health concerns should be evaluated through an appropriate remediation or health professional.
Coverage varies by policy and by the cause of the loss. Insurance often treats sudden plumbing damage differently from groundwater seepage, maintenance or long-term foundation conditions. Ask the insurer to interpret the specific policy; a contractor should not guarantee coverage.
