Interior Basement Waterproofing in Wellesley, MA

Keeping Wellesley Basements Dry From the Inside

Interior drainage and sump pump systems, built for Wellesley's older homes.

All Pro Basement Waterproofing stops basement water in Wellesley, MA from the inside. We catch it where the wall meets the floor, the spot where most basements leak, carry it to a sump pump and send it outside, away from the foundation and never into the town sewer. The same system works on the fieldstone and early concrete foundations under many older Wellesley homes, as well as on newer poured walls. The company is run by owner Diego Tameirao, with 25+ years of basement experience and 5.0 stars on Google.

How it works

How an Interior System Keeps Water Out

Three pieces that work together every time it rains.

Drainage at the Footing

A channel set into the floor along the walls catches water where the wall meets the slab, before it spreads across the basement.

A Sump Pump Sized for the Job

Collected water runs to a sump pit, where the pump kicks on as the level rises. Battery backup keeps it working when the power goes out.

Discharge That Leaves for Good

The discharge line exits the house and releases water away from the foundation, so it doesn't soak back into the soil against your walls.

Why Do Wellesley Basements Flood?

Older foundations and low ground near the brooks make water a local problem.

More than a third of the homes in Wellesley were built before 1940, and many of them stand on fieldstone or early concrete foundations. Those walls were built to carry the house, not to hold back groundwater. After decades of freeze and thaw, mortar loosens, joints open up and water finds the easiest way in, usually at the base of the wall.

Fuller Brook and Waban Brook carry runoff through town toward the Charles River, and Fuller Brook Park was created in 1899 partly for flood control. Homes on lower ground near the brooks often see water rise under the slab after long rains. See how we handled one of these walls in our Wellesley fieldstone foundation project.

What We Check Before Recommending a Fix

Every Wellesley basement leaks for its own reasons. These three come first.

Where the Water Gets In

We trace the entry point before anything else: the joint where wall meets floor, a crack, a gap between stones or water rising through the slab. Each one points to a different fix.

Where Your Sump Water Goes

Wellesley and MWRA rules don't allow sump pumps or groundwater to drain into the sanitary sewer. If an older pump in your house was plumbed that way, we reroute it outside.

What the House Actually Needs

If the real problem is one crack or a downspout dumping water at the foundation, we'll tell you. Interior drainage is the right answer for a lot of basements, not all of them.
