What We Do

Neither should you.

Our Services

Comprehensive protection
for every level of your home

Foundation Repair

Cracked, bowing, or settling foundations compromise your entire home. We diagnose the cause and restore structural integrity with pier systems, wall anchors, and epoxy injection — no guesswork.

Basement Waterproofing

Interior drain tile, exterior membrane systems, and sump pump installation — we seal your basement from the inside out so you can finally use that space for what it was meant to hold.

Learn more

Crawl Space Encapsulation

A damp crawl space is a recipe for mold, rot, and poor indoor air quality. We install vapor barriers, dehumidifiers, and sealed vents to transform your crawl space into a dry, protected envelope.

Foundation Inspections

Not sure if your home needs attention? Our thorough inspections identify early warning signs — stair-step cracks, sticking doors, efflorescence — before they become costly emergencies.

Learn more

Exterior Drainage

Proper grading, French drains, and downspout extensions keep water moving away from your foundation. We design drainage solutions tailored to your property's unique slope and soil conditions.

Emergency Repairs

Active leaks, sudden settling, or flooding after a storm — we offer rapid-response emergency service because water damage doesn't keep business hours, and neither do we.

About MAC Waterproofing

Local contractors who understand
your home's relationship with water

MAC Waterproofing was founded on a simple principle: homeowners in the Norristown area deserve waterproofing contractors who live here, know the soil conditions, and will treat your home like their own. We're not a franchise passing work to subcontractors — we show up on time, explain what we're doing, and stand behind every job.

From colonial homes on historic streets to newer constructions in developing neighborhoods, we've seen how Pennsylvania's freeze-thaw cycles and clay-heavy soil challenge foundations. That experience is what makes our assessments accurate and our solutions durable.

How It Works

From call to completion —
straightforward and stress-free

01

Call or message us

Reach out by phone or the form below. Tell us what you're seeing — damp walls, cracks, pooling water — and we'll schedule a visit at your convenience.

02

We inspect your property

Our technician evaluates the source of moisture or structural concern, explains the damage in plain language, and provides a detailed written estimate — no pressure, no upselling.

03

We complete the work

Once you approve the estimate, we schedule the project, keep you informed throughout, and clean up thoroughly when we're done. Your home should be drier and better than when we arrived.

04

We stand behind it
