What does basement waterproofing include?
Interior drainage, exterior waterproofing, sump pumps, leaking cracks and yard drainage.

Basement Waterproofing
Basement waterproofing stops water from entering a basement and removes water that collects around the foundation.
Learn more
Interior Drainage Systems
An interior drainage system (interior drain tile or French drain) is a perforated pipe installed in a trench along the inside perimeter of the basement floor.
Learn more
Exterior Foundation Waterproofing
Exterior waterproofing excavates soil down to the footing, cleans and repairs the wall, applies a waterproof membrane and drainage board, and installs new footer drains before backfilling.
Learn more
Sump Pump Installation & Repair
Sump pump service installs a sealed pit and pump where groundwater collects, replaces failed pumps and switches, adds battery or water-powered backups, and routes the discharge line well away from the house so it doesn't freeze or recirculate..
Learn more
Emergency Sump Pump & Flooded Basement Service
Emergency sump pump service gets water moving out of a flooding basement: replacing a failed pump or float switch, clearing a frozen or clogged discharge line, and adding a backup so the next storm or outage doesn't repeat it.
Learn more
Leaking Wall Crack Repair
Leaking crack repair seals non-structural cracks in poured concrete walls, usually by injecting flexible polyurethane that expands to fill the crack through the wall's full thickness.
Learn more
Yard Drainage, Grading & Downspouts
Yard drainage keeps rain and snowmelt away from the foundation: extending or burying downspouts, regrading soil to slope away from the house, and installing French drains or catch basins where water pools.
Learn moreWhat does foundation repair include?
Bowing walls, structural cracks, old sandstone foundations and settlement.

Foundation Repair
Foundation repair stabilizes and restores basement walls and footings: wall anchors, steel beams or carbon fiber for bowing walls, sealing or reinforcing structural cracks, repointing and rebuilding old sandstone and brick foundations, and piers for settling corners..
Learn more
Bowing Basement Wall Repair
Bowing wall repair stabilizes basement walls pushed inward by soil pressure, using wall anchors through the wall into the yard, steel beams from floor to joists, or carbon fiber straps bonded to the wall.
Learn more
Structural Foundation Crack Repair
Structural crack repair addresses cracks that indicate wall movement: horizontal cracks, stair-step cracks in block, cracks wider at one end, or displaced edges.
Learn more
Sandstone & Stone Foundation Repair
Stone foundation repair restores old sandstone, fieldstone and brick basement walls: repointing eroded mortar joints with compatible mortar, parging, replacing failed stones or rebuilding sections, and adding drainage so water stops washing out the joints..
Learn more
Foundation Settlement Repair
Settlement repair stabilizes parts of a foundation that have sunk, usually by driving steel push piers or helical piers to load-bearing soil and transferring the home's weight onto them, sometimes lifting the structure back toward level..
Learn moreWhat does crawl spaces include?
Encapsulation and drainage for damp, musty crawl spaces.

Crawl Space Repair
Crawl space repair controls moisture under the house: sealing the ground with a vapor barrier or full encapsulation, adding drainage and a sump where water collects, closing vents, and running a dehumidifier.
Learn more
Crawl Space Encapsulation
Crawl space encapsulation seals the crawl space from outside air and ground moisture with a heavy vapor barrier on the floor and walls, closed vents, insulated walls and a dehumidifier, turning it into a dry, conditioned space..
Learn more
Crawl Space Drainage
Crawl space drainage removes standing water under the house with a perimeter drain and a crawl space sump pump, plus outside fixes like downspouts and grading so less water arrives in the first place..
Learn moreWhat does moisture control include?
Dehumidifiers, mold prevention and leaking window wells.

Basement Moisture Control
Basement moisture control handles dampness that isn't a flood: high humidity, musty smells, condensation, mold on walls and leaking window wells.
Learn more
Basement Dehumidifiers
A basement dehumidifier removes moisture from basement air to keep humidity below about 50–60%, preventing musty odors, mold and condensation.
Learn more
Basement Mold Prevention
Basement mold prevention removes the moisture that feeds mold (leaks, condensation and humidity), then cleans affected surfaces and keeps humidity low.
Learn more
Window Well Leak Repair
Window well leak repair fixes water entering around basement windows by clearing or adding a drain at the bottom of the well, installing covers, regrading, sealing or replacing the window, and connecting the well drain to the drainage system..
