Professional Basement Waterproofing in Newmarket
If you’ve caught a musty smell coming from your basement, or noticed a wall that always feels a bit damp, you’re dealing with something a lot of Newmarket homeowners know well. It’s a common issue around here, and it’s almost always fixable once you know what’s actually causing it. At J.M WaterProofing, we deal with these basements regularly, and we know how to get to the root of the problem instead of just covering it up.
We’ve worked on homes across Newmarket, from the older character homes near historic Main Street to the newer subdivisions further south. Every house is a little different, but the end goal never changes: a basement that stays dry.
Why Newmarket Basements Run Into Trouble
Newmarket sits near Fairy Lake and the Holland River, and that low-lying land means groundwater tends to sit higher here than in a lot of surrounding towns. Combine that with clay-heavy soil that doesn’t drain well, and water ends up sitting against your foundation instead of moving away from it. Older homes near downtown deal with an extra layer of trouble too, since many were built long before modern waterproofing was standard practice.
A few things we see over and over:
- A high water table, especially closer to Fairy Lake and the Holland River
- Clay soil that traps water instead of letting it drain
- Foundations on older homes that were never properly waterproofed in the first place
- Cracks in the walls or floor, sometimes barely noticeable at first
- Grading that slopes toward the house instead of away from it
Signs Your Basement Might Need Attention
Some basements give obvious warnings, others are more subtle. Keep an eye out for:
- A musty smell that hangs around no matter how much you clean
- Walls that feel cold, damp, or discolored
- White, powdery marks on the concrete, known as efflorescence, which means moisture is passing through
- Paint bubbling or drywall softening near the bottom
- Mold showing up in corners or along the baseboards
- Cracks that seem to be getting wider over time
- Actual water on the floor after heavy rain or a fast snowmelt
Catching these early usually means a smaller, simpler fix, so it’s worth having someone look sooner rather than later.
What We Actually Do About It
Every basement is different, so we start by figuring out what’s really going on with yours. Here’s what we typically offer.
Interior Waterproofing
We install a drainage system along the inside base of your basement walls. It catches water before it spreads across the floor and routes it to a sump pump, which pumps it safely away from your home.
Exterior Waterproofing
The more complete fix. We excavate down to the foundation, apply a proper waterproof membrane, and replace the weeping tile if it’s damaged or clogged. Since it keeps water from ever reaching the wall, it’s often the better long-term choice for the older homes near downtown Newmarket.
Sump Pump Installation
Given how high the water table can get around here, a working sump pump isn’t optional, it’s essential. We install and service them, and we can add a battery backup so you’re still protected if a storm knocks the power out.
Foundation Crack Repair
Cracks tend to get worse, not better, if left alone. We seal them the right way, using methods that actually hold up, not just a surface patch.
Window Well Fixes
A window well with poor drainage is an easy way for water to sneak in. We fix the drainage and add covers so rain and melting snow stay out for good.

We keep things simple from start to finish.

There’s no shortage of waterproofing companies to choose from, so here’s the honest reason people stick with us.

Our crew has handled everything from a small hairline crack to a fully flooded basement, so there isn’t much that catches us off guard anymore. And when the job’s done, your property looks like we were never there, aside from the dry basement.
How long does a job like this take?
Interior work is typically finished in a day or two. Exterior waterproofing takes longer because of the digging involved, but we’ll walk you through a realistic timeline before we start.
Will it make a mess of my yard?
Exterior work does involve some digging, but we’re careful around landscaping and clean up thoroughly once we’re finished.
