Catonsville Foundation Work

Parging Catonsville's Older Foundations

The homes along Frederick Road, Edmondson Avenue, and throughout western Baltimore County were built on concrete block — solid construction, but the original parge coats are now 60–100 years old. When that parge cracks or peels away, moisture enters the block and eventually finds its way inside.

We've worked on hundreds of Catonsville foundations. We know the block types and failure patterns common to this area, and we mix and apply parging that holds up through Maryland's freeze-thaw cycles.

What We Do

✓ Parge coat repair — patch cracked, spalled, or delaminated sections
✓ Full re-parge — strip old parge and apply a fresh coat
✓ Crack repair — horizontal, vertical, and stair-step cracks filled and bridged
✓ Chimney parging — mortar cap and crown repair on block chimneys
✓ Waterproofing coat — hydraulic cement or additive for exposed areas
✓ Above-grade block walls — parging on exposed block above grade

FAQ

Catonsville Foundation Parging Questions

What is foundation parging?

Parging is a thin coat of mortar or cement-based material applied to the exposed face of a foundation wall — usually concrete block. It seals the porous surface, fills voids, and creates a smooth, weather-resistant finish. Most older Catonsville homes have parged foundations that need repair as the original coat ages.

Does parging waterproof a foundation?

Parging significantly reduces moisture infiltration on exposed above-grade foundation walls and is an effective first defense against water. For foundations with significant hydrostatic pressure or active water infiltration, additional waterproofing measures may be needed. We'll give you an honest assessment of what will actually solve your situation.

How long does parging last?

Properly applied parging on a stable foundation typically lasts 20–30 years in Maryland's climate. Failure comes faster when there's ongoing foundation movement, poor surface preparation, or an incorrect mix. We prep properly and mix for longevity — not for speed.

How much does foundation parging cost in Catonsville?

Most residential foundation parging in Catonsville runs $8–$15 per square foot depending on the condition and square footage of the foundation. We provide written estimates — call to schedule an assessment.

Should I repair or replace the parge coat?

If cracks are isolated and the rest of the parge coat is still bonded, repair is sufficient. If the parge is failing broadly — hollow-sounding throughout, spalling in large areas, or no longer bonded to the block — full replacement gives you a better starting point. We'll tell you which approach makes sense after we look at it.

When is the best time of year to parge a foundation?

Spring and fall are ideal — moderate temperatures with good curing conditions. We avoid hot direct sun and freezing temperatures. We can work most of the Maryland spring, summer, and fall with appropriate precautions.
