Basement Waterproofing in Georgetown
Georgetown sits on Halton Till, a stiff glacial clay-loam over Queenston shale, and that clay holds meltwater against a foundation long after the snow is gone. Foundations in the older blocks around Main and Church predate modern drainage. We waterproof two ways, an interior weeping-tile system or an exterior excavation and membrane, and we pick the one your wall needs. The site visit and the written quote are free, the labour is warranted for life, and from October to March water coming in right now can be flagged urgent.

Georgetown sits on the east, downhill side of the Niagara Escarpment, on Halton Till, a stiff glacial clay-loam laid over the red Queenston shale. That clay holds meltwater against a foundation long after the snow is gone, which is why so many cellars here run damp in March.
The water finds a crack, a tie hole or the joint where the floor meets the wall. Waterproof paint rolled on the inside of a wall holds back that pressure for a season, then blisters off. Until the water has somewhere better to go, it keeps coming: it has to be collected at the footing, or kept off the wall from the outside.
We install both kinds of system and tell you plainly which one your wall needs once we see where the water gets in. The full method, the weeping tile, the sump, the exterior membrane, is on our basement waterproofing page. This page is about why Georgetown's ground and its older streets keep some basements wet, and how we handle it here. Use the form for a free written quote.
Why the older Georgetown streets take on water
Georgetown grew outward in waves, and the age of the street tells you a lot about the basement. The oldest blocks sit around Main and Church, the railway pushed a second wave out toward King and Queen after 1856, and the postwar decades filled in Delrex and Moore Park. Foundations in the older core predate modern drainage.
Put a wall like that in clay that holds water, and spring is when it shows. The fix is rarely one product. A single leaking crack in a poured wall can be injected from the inside, the smaller job. Broader seepage tends to want regrading, downspout work, fresh parging on the exposed wall and interior drainage. We start with the cause and tell you what each step will and will not solve.
Georgetown South: newer homes, settling ground
Newer does not always mean dry. Georgetown South has been built out survey by survey since 1989, much of it on disturbed clay fill, and foundation backfill keeps settling for a season or two after the builder hands over the lot.
On these lots we look at the grade and the downspouts as well as the wall. Where water is already coming through the wall or up at the floor joint, we look at how the wall is built and size a system to it, not a template.
Shallow shale, and why we look before we dig
Exterior waterproofing means digging down to the footing, and in Georgetown the ground can change from one block to the next. South of the town the glacial cover thins and the Queenston shale comes up close to the surface in places, while a short distance away it is buried under deep clay. A dig that is routine on one street can hit rock on the next.
That is one reason we read every lot on the site visit before we quote. It tells us whether an exterior membrane is practical on your wall or whether an interior weeping-tile system and sump is the better route. Interior or exterior gets decided by the wall and the ground, not by what we would rather sell. Exterior excavation needs unfrozen ground, and booking in summer means the work happens in dry ground on a regular route.
Straight answers
Why does my Georgetown basement get damp every spring?
The clay is a big part of it. Georgetown sits on Halton Till, a stiff glacial clay-loam, and it holds meltwater against the foundation long after the snow has gone. In the older blocks near Main Street the foundations also predate modern drainage. Until the water has somewhere better to go than through the wall, it keeps coming.
We have an older home near Main Street. Can the wet basement be fixed?
Usually, yes, once we find how the water gets in. A single leaking crack is injected from the inside. Broader seepage tends to want regrading, downspout work, fresh parging on the exposed wall and interior drainage rather than one product. We trace the cause first and tell you plainly what each step will and will not solve.
Our Georgetown South house is fairly new. Why is water getting in?
The ground around a new home keeps moving for a while. Much of Georgetown South is built on disturbed clay fill, and the backfill against the foundation settles for a season or two after handover. We look at the grade and the downspouts as well as the wall, and tell you plainly what each step will and will not solve.
Interior or exterior waterproofing for a Georgetown home?
The wall and the ground decide it. An interior weeping-tile system and a sump installs without digging up the yard and handles most leaking walls well. Exterior excavation and a membrane is the bigger job and keeps the wall itself dry, which matters when an old wall is breaking down from years of wet. In parts of Georgetown shallow shale changes how deep a dig can go, so we look at the lot before we recommend either.
How much does basement waterproofing cost in Georgetown?
It turns on the method and the wall. An interior system and an exterior dig are different jobs, so a flat rate would only mislead you. The depth to the footing, access on the lot, the length of wall, the state of the existing drainage and the soil all move the number. We write a real one after a free site visit, and the number on the written quote is the number on the invoice unless you change the job.
