When water stops finding its way into your basement, a lot of other problems stop too. The musty smell that you’ve been blaming on “old house character” — gone. The efflorescence creeping up your foundation wall — no longer spreading. The low-grade anxiety every time a storm rolls in off the Wissahickon watershed — finished.
McKinley’s housing stock is almost entirely pre-1950 construction. That means clay-heavy soil pressing against aging stone and concrete foundations that were never designed to handle sustained hydrostatic pressure. A properly installed french drain system intercepts that groundwater before it ever reaches your wall — not after it’s already soaked through.
The lots here are modest, too. Many are a quarter acre or less, which limits what we can do with surface grading alone. When there’s no room to regrade your yard away from the foundation, a french drain isn’t one option among many — it’s the option. And when it’s installed correctly using rigid perforated PVC, proper filter fabric, and the right slope, it’s a 30-to-40-year solution, not a patch.
We’ve been working in Montgomery County for about two decades. That’s long enough to know what’s behind the walls of a 1940s home on Cadwalader Avenue in McKinley, what Abington Township’s stormwater ordinance actually requires, and why the clay soil in this part of the county creates the exact drainage conditions that keep basements wet year after year.
What genuinely separates us from every other drainage contractor serving McKinley, Jenkintown, and Elkins Park is the environmental piece. We hold a Certified Lead Inspector and Risk Assessor credential — a federally recognized designation that virtually no waterproofing or drainage contractor in this region carries. In a neighborhood where the median home was built in 1949, that credential isn’t a bonus. It’s the reason you can trust the work is being done safely.
Fully licensed, bonded, and insured at the environmental services level. Free estimates. Cash discounts available. And someone answers the phone at any hour — because water doesn’t wait for business hours.
It starts with a free estimate. Someone comes out, looks at your property, and gives you a straight assessment of what’s happening and what it’s going to take to fix it. For homes in McKinley — especially anything built before 1960 — that assessment includes evaluating the foundation condition, the soil drainage characteristics, and whether any pre-existing hazardous materials need to be addressed before excavation begins. That last part matters more here than in most places.
If the project involves exterior excavation near the foundation, we test the environment first. Lead-contaminated soil, lead paint on foundation walls, asbestos in pipe insulation — these are realistic possibilities in McKinley homes from the 1940s and 1950s, and they require certified handling, not guesswork. HEPA filtration is standard on any job where airborne risk exists. Once the environment is confirmed safe, installation proceeds — proper perforated PVC pipe, geotextile filter fabric, clean crushed stone, and a calculated slope that actually moves water where it needs to go.
Abington Township has an active stormwater management ordinance, and depending on the scope of work, a permit may be required. We know the township’s requirements and handle the process correctly. When the job is done, the system is built to last — not to look good for six months and fail by year three.

French drain installation in McKinley typically falls in the range of $3,000 to $8,000 depending on whether the system is interior, exterior, or both — and how much linear footage the project requires. Interior systems run roughly $40 to $85 per linear foot. Exterior systems, which involve perimeter excavation, run $10 to $50 per linear foot depending on depth and access. On a street like Tulpehocken Avenue or Roanoke Road, where lot sizes are tight and established landscaping limits equipment access, exterior work requires more planning and care. That affects scope, and we’ll walk you through exactly what your property calls for before any commitment is made.
What you’re getting isn’t just pipe in a trench. It’s a system designed for the specific drainage conditions in McKinley — clay soil that holds water, aging foundations that weren’t built with modern waterproofing in mind, and a watershed that puts real hydraulic pressure on properties throughout Abington Township every spring. The difference between a system that lasts 30 years and one that fails in three comes down to materials and installation quality. We use rigid perforated PVC — not corrugated flex pipe — and don’t skip the filter fabric that keeps the system from silting up over time.
If hazardous materials are found during the pre-installation assessment, we handle remediation in the same engagement. No coordinating separate contractors, no gaps in responsibility, no wondering who owns the problem if something is missed.
It depends on the scope of the project. Abington Township operates under an active Stormwater Management Ordinance — Ord. No. 2100, adopted in 2016 — and properties in the township are also subject to NPDES MS4 permit requirements and the Wissahickon Creek Watershed Act 167 stormwater management plan. For most interior french drain installations, a permit is typically not required. For exterior work that involves significant excavation, changes to grading, or connections to the municipal stormwater system, a Stormwater Management permit may be required before work begins.
McKinley straddles two townships — Abington and Cheltenham — so depending on which side of the boundary your property falls on, the applicable codes may differ. We’re familiar with both townships’ requirements and handle the permitting process as part of the project. You won’t be left figuring that out on your own.
The honest answer is that it varies, and any contractor quoting you a firm number before seeing your property is guessing. That said, most french drain projects in McKinley fall somewhere between $3,000 and $8,000 for a complete system. Interior installations generally run $40 to $85 per linear foot. Exterior installations — which involve excavating around the foundation perimeter — typically run $10 to $50 per linear foot, though depth, access, and soil conditions all affect the final number.
In McKinley specifically, the clay-heavy soil and older foundation types common to homes built in the 1940s and 1950s affect how the system is designed and what materials are required. If pre-installation environmental testing reveals lead-contaminated soil or other hazardous materials near the foundation — which is a real possibility in any pre-1978 home — we handle that work as part of the same engagement rather than as a separate cost surprise later. The free estimate is the right starting point — it gives you a clear, itemized picture before you commit to anything.
This is one of the most common frustrations homeowners in McKinley bring to us. The short answer is usually that the previous fix addressed symptoms rather than the source. Patching a crack in a foundation wall doesn’t solve the hydrostatic pressure building up against it from saturated clay soil. A sump pump that runs constantly isn’t fixing the drainage problem — it’s just managing the water that’s already gotten in.
The real issue in most McKinley homes is that the soil around the foundation holds water instead of draining it. Montgomery County’s clay-heavy soil is well-documented as a primary cause of chronic basement water problems in older neighborhoods like this one. A properly installed french drain system changes the equation by intercepting groundwater before it ever reaches the wall. When the system is designed correctly for the soil conditions and foundation type specific to your property, the pump runs less, the wall stays dry, and the problem is actually solved — not temporarily managed.
This is exactly the right question to ask — and the fact that most drainage contractors don’t bring it up is a real problem. In McKinley, where the median home was built around 1949, virtually every property was built before the EPA’s 1978 lead paint threshold. That means lead-based paint on exterior foundation walls, lead-contaminated soil from decades of paint flaking, and potentially asbestos in pipe insulation or other building materials are realistic possibilities on almost any job site in this neighborhood.
We hold a Certified Lead Inspector and Risk Assessor credential — a federally recognized designation that no standard drainage contractor in the Abington or Jenkintown area carries. Before excavation begins on any pre-1978 property, we evaluate the environment, test where appropriate, and handle any hazardous materials found under EPA and HUD protocols with HEPA filtration containment. For families with young children or anyone with respiratory concerns, this isn’t an optional add-on. It’s the standard of care the housing stock demands, and it’s built into how we approach every job in McKinley.
An exterior french drain is installed around the perimeter of your foundation, typically at the footing level. It intercepts groundwater in the soil before it ever reaches the foundation wall — which is the ideal outcome. It requires excavation around the outside of the home, which on McKinley’s smaller lots can be tight depending on landscaping, structures, and property boundaries. When access allows and the water source is primarily from the surrounding soil, exterior is usually the more complete long-term solution.
An interior french drain is installed inside the basement, typically along the perimeter of the floor. It doesn’t stop water from entering the wall, but it captures water that has already infiltrated and channels it to a sump pump for discharge. Interior systems are less invasive, can be installed year-round regardless of ground conditions, and are often the practical choice when exterior access is limited — which is common on the smaller lots found throughout McKinley. In many cases, especially in homes with both soil-driven and wall-seepage issues, a combined interior and exterior approach is the most effective solution. We’ll tell you which one your property actually needs, not which one is easier to sell.
The cash discount is straightforward — processing fees on credit transactions are a real cost, and when a customer pays cash, those fees don’t exist. Passing that savings back to the customer is a simple way to make professional-grade work a little more accessible, especially for homeowners in McKinley who are already managing the costs that come with maintaining an older home. It has nothing to do with cutting corners on materials or labor.
The quality of the installation — the pipe specification, the filter fabric, the crushed stone, the slope calculation, the environmental testing protocols — is identical regardless of how you pay. We’ve been operating in Montgomery County for two decades, hold federal environmental certifications, and are fully licensed, bonded, and insured at the environmental services level. A cash discount doesn’t change any of that. It just means you spend a little less on a system that’s built to last 30 to 40 years.
