Interior Basement Waterproofing in Ashland, MA

Moving Basement Water Out of Ashland Homes

A footing drain, a sealed sump and a clear route outside for the water to go

In Ashland, interior basement waterproofing means giving groundwater a way out before it ever crosses the floor. We set a perforated drain along the footing, just under the edge of the slab, and slope it toward a sealed sump pit at the low corner. The pump then sends the water through a discharge line to a spot on your property where it drains away from the house. Owner Diego Tameirao has 25+ years on jobs like this and personally supervises each one. All Pro is rated 5.0 stars on Google.

Wet Seasons

Three Times a Year Basements Get Tested

The calendar says a lot about when the water shows up

Short, Heavy Summer Storms

A summer thunderstorm can dump a lot of rain in an hour. Gutters overflow, soil at the foundation floods and water finds the cove joint.

The Spring Thaw and Rain

Frozen ground thaws while spring rain keeps falling, and the water table climbs to its high point. This is when most basements leak.

Fall and Winter Nor'easters

Coastal storms stall and soak the region for days. The ground can't drain fast enough, and water pressure builds against the walls.

The Sudbury Runs Through Downtown

Ashland grew up along a river, and the town keeps close watch on where water goes

The Sudbury River cuts right through the center of Ashland, pooling at Mill Pond near Main and Myrtle Streets and passing under Concord Street by the library. A USGS gauge on the Front Street bridge has tracked its flow since 2006, measuring runoff from 35 square miles upstream. The river also powered Metcalf’s Mill, the Boston Marathon’s original starting line.

Town bylaw Section 247-2-7(F) says no one may tie a pump, cellar, yard, roof or area drain into the stormwater system without a permit, so a sump line can’t just be run out to the street drain. And in March 2010, between 10 and 20 inches of rain fell across eastern Massachusetts, a record-setting month for the region.

What to Know Before the Crew Arrives

A little prep on your end keeps the job moving and the rest of the house clean

Clear a Path Along the Walls

The crew works along the foundation walls, so shelves, boxes and anything else stored against them should be pulled toward the middle of the room before the first day of work.

Expect Noise From the Saw

Cutting the concrete at the floor edge is loud and throws dust for part of the job. Pets and anyone working from home usually do better on another floor while the saw is running.

Pick the Discharge Spot

The pump line has to leave the house and end where the water can soak in or drain away from the foundation. Town rules limit tying it into the street drain, so we walk the yard with you first.
