When water finds its way into a McKinley basement — whether it’s a slow seep after a heavy rain or a full flood after one of those summer storms that overwhelms the storm sewers — it doesn’t stay contained. It moves into framing, insulation, and drywall. Left alone, moisture becomes mold, and mold becomes a health issue and a much bigger bill.
The homes throughout McKinley were built predominantly between the 1920s and 1960s. That means most of these foundations are working with original drain tile — if it’s even still intact — and block or early poured concrete walls that were never designed to handle the hydrostatic pressure that builds up when Piedmont clay soils get saturated. These aren’t minor quirks. They’re the reason your basement feels damp every spring.
Getting this fixed means you stop losing storage space, stop worrying about what the inspector will say when you eventually sell, and stop breathing air that’s been sitting in a damp basement for months. With a median home value around $420,000 in Abington Township, protecting your foundation isn’t optional maintenance — it’s protecting a serious financial asset.
We’ve been working in Montgomery County for two decades. That’s not a marketing line — it means we’ve been inside the basements of homes just like yours in McKinley, Abington Township, Cheltenham, and the surrounding areas long enough to know what actually works and what just delays the next call.
We’re not a national franchise with a call center. When you reach us — and you can reach us any time, day or night — you’re talking to someone who knows what a 1949 block foundation on clay soil looks like from the inside. We handle testing, remediation, demolition when needed, and waterproofing as one team, not a rotating cast of subcontractors passing the problem around.
We’re fully licensed, bonded, and insured, and we carry EPA/HUD compliant certifications along with a Certified Lead Inspector and Risk Assessor on staff — which matters significantly in McKinley, where most homes predate 1978 and lead-containing materials in basement environments are the rule, not the exception.
It starts with a free estimate. We come out, look at the actual condition of your foundation, assess where water is entering and why, and give you a straight answer on what needs to be done. No pressure, no inflated scope designed to maximize the ticket. McKinley’s older housing stock often presents layered issues — a cracked block wall, a collapsed original drain tile, and a sump pump that’s been fighting a losing battle for years — and we want to understand the full picture before recommending anything.
From there, if hazardous materials are a concern — and in a home built before 1978, they often are — we handle testing and any required remediation before waterproofing work begins. This protects you, your family, and our crew. Abington Township requires permits for interior drainage system installations, and we handle that process so you don’t have to navigate it yourself.
The waterproofing work itself depends on what your basement actually needs. Interior drainage systems, sump pump installation or replacement, exterior membrane application, French drain installation — we match the solution to the problem. When the job is done, you’ll know exactly what was installed, why, and what to expect going forward. No mystery, no vague warranty language, no disappearing act.

Basement waterproofing isn’t one thing. For a McKinley home with a block foundation that’s been absorbing moisture through deteriorating mortar joints for fifty years, the fix looks different than it does for a poured concrete wall with a single active crack. We approach every job as a diagnostic first — we’re not here to sell you a system, we’re here to fix your specific basement.
For most homes in McKinley, that conversation covers interior perimeter drainage channels, sump pump installation or upgrade, and vapor barrier systems for crawl spaces where applicable. Homes with more significant water intrusion or exterior grading problems may need exterior excavation and membrane waterproofing. Because we also handle mold remediation and demolition in-house, we can address damaged framing, drywall, or insulation that moisture has already compromised — without you having to coordinate a second contractor.
Montgomery County’s documented increase in stormwater runoff and the clay-heavy Piedmont soils under McKinley mean that waterproofing here isn’t a one-and-done patch job — it’s a system designed to manage ongoing hydrostatic pressure. We size and install accordingly. And because we offer cash discounts and free estimates upfront, you know what you’re getting into before any work starts.
The most common reason is a combination of factors that are specific to McKinley. This neighborhood sits on Piedmont clay soils, which have very low permeability — meaning water doesn’t drain away from your foundation during heavy rain, it pools against it and builds pressure. That pressure pushes through any weak point: mortar joints in block walls, hairline cracks in poured concrete, gaps around pipe penetrations, or the floor-wall joint at the base of your foundation.
In McKinley, where most homes were built between the 1920s and 1960s, the original perimeter drain tile — if it was ever installed — is likely collapsed, crushed, or clogged with root intrusion after 60 to 80 years underground. The mature tree canopy throughout the neighborhood is beautiful, but those root systems actively seek moisture and frequently compromise drainage systems over time. When the original drainage fails and the soils are saturated, water has nowhere to go but in.
The honest answer is that it depends on what your basement actually needs, which is why a free estimate matters more than a ballpark number. That said, for a typical interior drainage system with sump pump installation in a home of the size and age common in McKinley, you’re generally looking at a range of $5,000 to $12,000. More extensive work — exterior excavation, membrane application, or jobs that also require mold remediation or damaged material removal — will run higher.
What affects the cost most is the scope of the problem: how many linear feet of drainage channel are needed, whether the sump pump basin requires new excavation, whether existing mold or damaged framing needs to be addressed first, and whether hazardous materials testing is required. In a pre-1978 home — which describes the vast majority of McKinley’s housing stock — lead paint testing and compliance protocols are often part of the process. We offer cash discounts, and your estimate will be specific to your actual job, not a generic starting price designed to get a foot in the door.
Mold is extremely common in basements throughout McKinley, and it’s almost always a downstream consequence of moisture — not a separate problem. When water has been seeping into a basement seasonally for years, it creates the sustained humidity that mold needs to establish and spread. In a home with original wood framing from the 1940s or earlier, mold can work through floor joists and subflooring and eventually affect the living spaces above.
Waterproofing addresses the source of the moisture, which stops the conditions that allow mold to grow. But if mold is already present, it needs to be properly remediated before or alongside the waterproofing work — sealing a basement that still has active mold growth doesn’t solve the problem, it just traps it. We handle both in-house, using HEPA filtration systems and professional remediation protocols, so you’re not coordinating two separate contractors or leaving the mold issue to deal with later.
For most interior drainage system installations — perimeter channels, sump pump basins, interior French drains — yes, a building permit is typically required in Abington Township. Pennsylvania follows the International Residential Code, and Abington Township enforces those standards through its building and codes department. Exterior waterproofing work that involves excavation also requires permits and PA One Call (811) utility notification before any digging begins.
Sump pump discharge is another area where local rules apply — where and how you discharge the water matters, and it needs to comply with Abington Township’s stormwater ordinances. The township has been actively investing in stormwater infrastructure improvements in recent years, which reflects how seriously local officials take drainage management in the area. We handle the permit process on your behalf, so you’re not navigating the township’s requirements on your own or risking work that doesn’t pass inspection.
Interior waterproofing manages water after it enters the foundation wall — we intercept it at the base of the wall and channel it to a sump pump before it can spread across your floor. This is the most common approach for homes in McKinley because it’s less disruptive, doesn’t require excavating around the exterior of the house, and is highly effective at managing the kind of hydrostatic seepage that’s typical with clay soils and aging block foundations.
Exterior waterproofing addresses the problem at the source by excavating down to the foundation footing, applying a waterproof membrane to the outside of the wall, and installing drainage board and exterior drain tile to direct water away before it ever contacts the foundation. It’s a more involved job and typically costs more, but in cases where the exterior wall itself is deteriorating or where grading and drainage issues are severe, it’s the more appropriate long-term solution. Most McKinley jobs end up using interior systems, sometimes in combination with targeted exterior work on a specific wall or corner where conditions are worst.
There are several established waterproofing contractors targeting the Abington and Elkins Park market — some with decades of local presence, some that are regional franchise operations with national backing. The real question isn’t who has the biggest ad budget; it’s who will actually diagnose your specific basement correctly and fix the right problem.
EJS Environmental Services LLC brings something most waterproofing-only contractors can’t: the ability to handle the full chain of issues that older McKinley basements present. If there’s mold, we remediate it. If there’s damaged framing or drywall, we handle demolition. If there are lead paint concerns in a pre-1978 home — which is most homes in this neighborhood — our Certified Lead Inspector and Risk Assessor manages that process in compliance with EPA and HUD standards. You’re not managing handoffs between three different contractors or hoping each one shows up when the other finishes. We also offer cash discounts as a straightforward way to pass real savings to homeowners who prefer to pay that way — it reduces our processing costs, and we pass that directly to you. Free estimates, 24/7 availability, and two decades of experience in Montgomery County round out what makes the difference on a job like this.
