Richmond Hill is built on the Oak Ridges Moraine, a ridge of glacial sand and gravel that Yonge Street follows north through the city. The housing sits in two ages: century homes and original foundations around old Yonge Street and Mill Pond, and newer surveys pushing north toward Oak Ridges and Lake Wilcox.
Not every foundation crack is the same job, so the first step is telling them apart.
The full method, from epoxy and polyurethane injection to carbon fibre straps, is on our foundation repair page. This page is about what Richmond Hill's ground and its mix of old and new housing change about the job.
What moraine ground means for a foundation wall
Sand and gravel drain fast, so frost has less water to grab than it does in clay. That is good for a wall, but it does not make cracks go away. Settling, shrinkage and a poorly graded lot still crack foundations here, and loose granular ground can shift as it finds its level.
The moraine is also a major groundwater recharge area, and the wet spots are local and easy to miss. Around Oak Ridges and Lake Wilcox the land sits over kettle lakes and old wetland, and the water table can climb close to the surface after the melt. A wall there can leak when the lot next door stays dry, so we look at the ground, downspouts and drainage as well as the crack.
Century homes and new surveys
Around Mill Pond and old Yonge Street, the foundations predate modern pours. After decades the parging cracks off, steps settle and basement walls start to weep. We inject the cracks that leak, reinforce a wall that is actually moving, and repair the parging once the wall is sound; see parging.
In a newer survey up north, grading that slumps can send water back toward the house. If a crack there starts to leak, injection seals it from the inside, usually without digging.
When a crack is really a wet-basement job
If water is not coming through one crack but along the wall, or only after the spring melt, the job may be basement waterproofing rather than a crack repair. We sort out which job your wall needs at the free visit, before we quote either one.
Straight answers
Do you do small foundation crack repairs in Richmond Hill?
Yes. One leaking crack is a welcome job. Richmond Hill is north and east of our home routes, so we book it into a planned trip into York Region and give you a real date rather than a same-week promise. A small job gets the same free written quote as a large one.
Our Richmond Hill basement gets damp near Lake Wilcox. Is that a foundation repair?
It can be. In the Oak Ridges and Lake Wilcox pockets the water table rises close to the surface after the melt, so a wall can take water even when the sand drains well most of the year. We find what is letting the water through, whether it is a crack, the grading or the drainage, before we pick a fix.
We own a century home off old Yonge Street. Can you repair the original foundation?
We can. The work is matching what is there: injecting cracks that leak, reinforcing a wall that has moved, and re-parging once the wall is sound. We look at the cracks at the free visit and tell you plainly which need work.
My newer Richmond Hill home has a crack in the basement wall. Is it serious?
We measure the crack at the free visit and tell you plainly whether it needs work. A crack that leaks is one we can seal by injection.
How much does foundation repair cost in Richmond Hill?
There is no honest flat rate, so we quote on inspection rather than publishing a number. The visit and the written quote are free, and the number on the quote is the number on the invoice unless you change the job.
