Every moisture problem has a different source. We identify yours specifically before we quote anything — then we deploy the right system, not the most expensive one.

Interior French Drain & Perimeter Drainage Systems
When hydrostatic pressure is the primary culprit, the most effective long-term solution is a properly engineered interior drainage system. We install sub-slab perforated drain tile around the perimeter of your basement — capturing water before it can rise above slab level — and route it to a sump pit equipped with a dual-pump configuration.
These systems don't fight hydrostatic pressure — they redirect it.

Exterior Foundation Coating & Drainage Board Installation
Exterior waterproofing is the most comprehensive solution available — stopping water before it contacts your foundation wall. We excavate to the footing, apply a rubberized polymer membrane to the exterior foundation face, install dimple-mat drainage board, and backfill with clean crushed stone to redirect surface water away from the structure.
This approach solves the problem at the source: water never reaches your interior wall surface.

Poured-Wall Crack Injection & Block Wall Repointing
We inject poured-wall cracks using a port-and-backer system: surface ports are installed at 8–12 inch intervals along the crack, the surface is sealed with hydraulic cement, and two-part polyurethane or epoxy is pumped under pressure from the lowest port up — filling the crack through its full depth.
Block wall repointing involves removing deteriorated mortar joints to a minimum depth of 3/4 inch and repacking with waterproof hydraulic mortar.

Crawl Space Moisture Control: Encapsulation to Full Waterproofing
We install a minimum 20-mil reinforced poly vapor barrier over the entire crawl space floor and seal it up the walls to the sill plate — then seal all vents, install a conditioned air supply or dedicated crawl space dehumidifier, and spec a sump system if groundwater is present.
For crawl spaces with active water entry, we install a perimeter drain channel at the footer line, route it to an appropriate discharge point or sump.

Primary & Backup Sump Pump Systems for Haviland Homes
The sump pit itself matters as much as the pump. We construct 18-inch diameter pits with a gravel bed at the base for proper water collection, sealed lids to prevent vapor and radon entry, and a discharge line that terminates a minimum of 10 feet from the foundation at a positive-grade daylight point.
For finished basements and properties with high groundwater, we recommend a dual-pump system: a primary submersible at normal operating level and a pedestal backup set two inches higher.

Basement Window Well Repair & Drainage Installation
Basement window wells are one of the most underestimated water entry points in residential waterproofing. When the well drain becomes clogged or the well itself is sized incorrectly for your roof drainage load, water pools against the window frame and enters through the sill, the window-to-frame joint, or the block wall directly adjacent.
Egress window installations create a significant opening in your foundation wall, and sealing the rough opening properly is as important as the window itself.
