Basement Waterproofing

Keep Water Out. Protect What Matters.

Basement moisture doesn’t appear out of nowhere. It travels through soil, works around your foundation, and finds its way inside through crevices you may not even see. And getting to the bottom of it starts with understanding the entire picture.

That’s the approach we bring to every basement waterproofing project at Allmaster Home Services. Rather than jumping to a quick fix, we take a step back. Is runoff pooling near your foundation after heavy rain? Is saturated soil building up pressure against your walls? Often, it’s a mix of factors working together. Whatever’s driving the moisture in your home, we’ll find it and fix it the right way.

What You’re Seeing vs. What’s Really Happening

A damp basement is your home's way of flagging something worth paying attention to. The moisture itself is usually a symptom, not the root cause, and it can show up in ways that are easy to overlook at first.

Homeowners in Pasadena and the surrounding area commonly notice things like:

A persistent musty smell, even without visible water
Chalky white residue forming along the walls
Damp spots near the floor or along the perimeter
Small cracks that are developing in the foundation
Mold appearing in corners or on lower portions of drywall

Left unaddressed, moisture can seep into wood framing, putting pressure on structural components. Dealing with it early is almost always the more straightforward, less costly route.

The Hidden Tradeoffs of Older Foundations

If your home was built with a block or stone foundation, you’re already dealing with materials that handle moisture differently than modern poured concrete. Block foundations allow some moisture to pass through naturally, and stone foundations often have aging mortar joints that create additional pathways for water to enter.

Add in the clay-heavy soil common throughout Anne Arundel County, along with Maryland's consistent rainfall, and it becomes apparent why basement moisture is such an issue in this region. It’s not a flaw in how these homes were built, but rather the reality of older construction meeting local conditions. The key is to work with what’s happening, not against it.

How We Control & Redirect Water

No two homes handle moisture the same way, which is why we offer a range of interior and exterior options that can be combined to suit your property's needs.

These are some of the solutions we typically recommend:

Yard drainage improvements to redirect surface water before it reaches the foundation
Downspout extensions that move runoff further from the home
Interior drainage systems to capture and channel water
Sump pump installation to remove collected water efficiently
Crawl space encapsulation with vapor barriers and drainage components
Targeted leak repair and sealing where entry points are identified

Sometimes one method is all it takes. Other times, it takes multiple of these to fully solve the problem. We’ll always be upfront about which direction makes sense for your home.

A Process That Follows the Evidence

Transparency is built into everything we do. Before, during, and after the job, you’ll always know where things stand and what comes next. Here’s what to expect:

Assess

A phone call can only tell us so much. We’ll visit your home and take a close look at everything from foundation conditions to how your yard handles water after a storm.

Explain

Before we talk solutions, we’ll share our findings and answer any questions you have. You should feel confident and informed before anything else happens.

Plan

Every property is different, and your recommendation will reflect that. We’ll map out what needs to happen, in what order, and why, because every step of the plan has a purpose.

Execute

Our technicians arrive when they say they will and see the job through without unnecessary delays. Your home is treated with the same care we would want for our own.

Back

Good work should last, and we back ours up. Warranty details vary by system, and we’ll walk you through what’s covered with yours before we wrap up.

We’ve been doing it this way for decades, and it works. Not just for the homes we service, but for the homeowners we build lasting relationships with.

Frequently Asked Questions

If moisture appears near the foundation primarily after heavy rain, surface drainage may be all that’s needed. If it shows up along walls or floor edges, or persists over time, the foundation is likely involved. An inspection will clarify which situation you’re dealing with.

Absolutely. Block and stone foundations are popular throughout this area, and we work with them regularly. The solution just needs to account for how those materials behave.

We create a pit at the lowest point in your basement, install the pump and float system, and run a discharge line to safely carry water away from the home.

Yes! Warranty details depend on the type of system installed. An Allmaster specialist will cover all of that during your consultation.

Even after installing a new energy efficient heating/AC system the previous year, the AC bill was much lower than it was the year before(barrier) and my heating bill this last, long cold snowy winter was lower than it’s ever been in the thirty years I’ve lived here! Great job guys!
