Water has a way of finding the smallest opening and making itself at home. Our basement waterproofing work combines membrane installation, exterior trenching, and interior water mitigation, so we can handle seepage coming through the walls, water pushing up from below, or both at the same time.
Mold needs damp air to get started, which is exactly what a dehumidifier takes away. Our dehumidifier installation service puts a mold mitigation device to work, pulling airborne moisture down to a level where mildew and musty smells cannot survive. Any brand works for us, so bring us the unit you want or let us recommend one.
Plenty goes wrong under a house before anybody notices. Our crawl space repair service covers ductwork repair, debris removal, and vent sealing, plus the structural side of things: damaged beams, weakened joists, and failing piers all get fixed so sagging floors firm back up.
Think of encapsulation as sealing off the crawl space from the ground and the outside air entirely. Our crawl space encapsulation package brings together a vapor barrier, sump pump, dehumidifier, insulation, and French drains, all working as one system to lock moisture out.
Cold floors in January and a house that never quite cools down in August often trace back to what’s missing underneath. Good crawl space insulation slows heat transfer, which takes strain off your HVAC and knocks money off the monthly bill. We use materials built to hold up in a damp environment rather than soak it up.
Keeping water out from the start beats cleaning up after it every time. Our crawl space waterproofing solutions combine drainage systems, sump pumps, and vapor barriers, and French drainage often plays a part in moving water away before it ever reaches the foundation.
Drains and vapor barriers handle the water you can see, but humid air still carries plenty of moisture on its own. Crawl space dehumidification takes care of what is left, pulling airborne moisture out so the space stays dry and the air upstairs smells better. Put all three together, and you end up with a crawl space that actually protects your foundation instead of slowly wearing it down.
Some homes collect water no matter how well the grading and drainage are set up, and that’s where a pump earns its spot. A sump pump installation gives that water somewhere to go before it reaches your basement or crawl space. If a foundation repair calls for extra drainage, we build the pump into the plan from the beginning.
When water pools against a foundation, the pressure it creates has to go somewhere, and usually that means into your basement. A French drain installation gives runoff a path away from the structure, which protects the foundation, keeps your yard from washing out, and takes the hydrostatic pressure off your walls.
Cracks in the drywall, doors that stick, floors that slope toward one corner: these all point to the same place. Our foundation repair work covers leveling, crack repair, push pier installation, bowing wall stabilization, and the waterproofing that keeps the problem from coming back. We figure out what caused the movement first, then fix it in a way that holds.
Sometimes a foundation is too far gone for patching, and rebuilding is the honest answer. Foundation replacement can mean a footing re-pour, a crawl space wall re-pour, or a full replacement, depending on what the inspection turns up. We walk you through exactly what needs doing and why before anything gets torn out.
That soft spot in the hallway usually means water got to the subfloor a while back. Our subfloor repair and replacement service removes the damaged material and puts down new decking, so the floor feels solid underfoot again. Fixing the moisture source at the same time keeps the new subfloor from ending up like the old one.
Most contractors around here take one look under a mobile home and pass, which is why we made it something we do well. Mobile and modular home foundation repair means dealing with settling piers, broken tie-downs, and sagging floors, and it takes a crew willing to work in tight, awkward spaces. We’re that crew, and we’re glad to have the work.
A sunken driveway slab or a patio that has tilted toward the house doesn’t require tearing out the concrete. Concrete leveling and lifting uses polyurethane foam injected underneath to raise the slab back where it belongs, and the job is clean, quick, and usually ready to walk or drive on the same day.
When a house settles because the soil underneath gave out, adding support to that same soil won’t help. Push pier installation drives steel piers down past the unstable ground until they hit load-bearing soil or bedrock, then transfers the weight of the house onto them. Once the piers reach refusal, we can often lift the structure back toward its original elevation, closing cracks and straightening things out along the way.
Soil pushes hard against basement walls, and when it swells with moisture or freezes, that pressure can bend a wall inward. Bowing basement wall repair stabilizes the wall to stop the movement before you end up with horizontal cracks, water coming in, or uneven floors overhead.
Basements around here take a beating during spring storm season, and the fix depends entirely on how water is getting in. Our basement waterproofing work combines membrane installation, exterior trenching, and interior water mitigation, which lets us handle seepage through walls, water pushing up through the floor, or both at once. Cracks get sealed, drainage gets rerouted away from the structure, and the moisture that used to soak into concrete and warp your framing stops arriving in the first place.
Drying out the structure only gets you partway there, because humid air carries plenty of moisture on its own. That is why we install dehumidifiers, which act as mold mitigation devices by pulling airborne moisture down to a level where mold and mildew simply can’t get established. Any brand works for us, so if you already have a unit picked out or one that needs replacing, we can put it in and set it up correctly.
Crawl spaces hide problems well, which is what makes them expensive when nobody looks. Our crawl space repair covers ductwork repair, vent sealing, and debris removal, along with the structural side: damaged beams, weakened joists, and failing piers all get repaired or replaced so the floors above stop sagging and bouncing. Getting under there and stabilizing what has shifted keeps small issues from turning into a subfloor replacement or a leaning wall later.
When water shows up at midnight on a Saturday, and you can’t wait until Monday, we answer the phone and get someone headed your way.
We hold a Concrete Raising Certification along with a Licensed Push Pier Installer credential, so the work meets real industry standards rather than whatever seems close enough.

Not always. Sump pumps earn their keep in homes where water actually collects, meaning basements below the water table, crawl spaces that pool after storms, or properties sitting at the low point of a lot. A home on higher ground with good grading and working gutters may never need one. The only way to know is to have someone look at where water goes during a heavy rain, which is part of any decent waterproofing service inspection.
Summers here are humid, and that moist air finds its way into crawl spaces through vents and gaps in the foundation. Once it hits the cooler surfaces underneath your home, it condenses into water droplets on joists, ductwork, and insulation. Mold takes hold, wood starts to rot, and the damp air gets pulled up into your living space through the floor.
The obvious ones are standing water, damp walls, and visible mold. The subtler signs matter just as much: a musty smell that never quite goes away, paint peeling or bubbling near the floor, white chalky residue on basement walls, floors that feel soft or bouncy, doors and windows that stick, and higher-than-usual humidity inside during summer. Any of these mean water is getting somewhere it shouldn’t be, and catching it early keeps the repair small.
A waterproofing service finds where water is entering a home or commercial building and stops it. That usually starts with an inspection of the basement, crawl space, foundation, and the grading around the property. Depending on what turns up, the fix might involve membrane installation, exterior trenching to move water away from the foundation, interior drainage, sump pumps, French drains, vapor barriers, or a dehumidifier to handle airborne moisture. Most jobs combine a few of these, since water rarely comes in through just one path.
The region gets heavy spring and fall rain, and the ground beneath many properties doesn’t drain evenly. Soil that swells when wet and shrinks when dry puts constant pressure on foundation walls, which is what causes cracks and bowing over time. Add sloped lots that funnel runoff toward the house, plus high summer humidity, and you have conditions that push water toward foundations year after year. Managing drainage and moisture is ongoing maintenance here rather than a one-time fix.
