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 Drain Tile & Perimeter Channel Systems
Interior drain tile systems collect groundwater at the footing level before it enters your living space. We saw-cut the slab perimeter, excavate to the footing, install gravel-bed perforated pipe, and tie it into a sump system with battery backup — so you stay dry even during power outages.
Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.

Full Excavation Exterior Waterproofing Systems
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.

Foundation Crack Injection — Polyurethane & Epoxy Systems
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.
For concrete block foundation walls showing horizontal cracking or inward bowing, we pair crack repair with carbon fiber reinforcement straps anchored at the floor and rim joist.

Crawl Space Encapsulation & Vapor Barrier Systems
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.
Encapsulation turns your crawl space from an uncontrolled dirt floor into a semi-conditioned space.

Primary & Backup Sump Pump Systems for Mount Vernon 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.

Egress Window Waterproofing & Well Cover Systems
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.
Window well covers are a maintenance measure, not a waterproofing solution — but paired with proper drainage installation.
