What we do
We don't do everything. We do the work below grade, in concrete, and the mold that comes with water — and we do it well.
Leaking and failing basement walls dug out, sealed and put right — from the outside where it matters.
Learn moreCracked steps, spalling walls, sunken slabs and failed joints repaired to last through Ottawa freeze-thaw.
Learn moreNew egress windows, walkout doors and enlarged openings cut into existing foundation walls.
Learn moreMold removed, the surface treated, and the moisture source it grew on actually fixed.

Foundation work disappears once it's backfilled, so we photograph every job. Drag the handle to compare.
Foundation Repair · Barrhaven · 2 days
Sample job · illustrative photos
Water tracking down the back wall every spring. Excavated to the footing, repaired the crack, rebuilt the membrane and drainage, and regraded so surface water runs away from the house.

Sample job · illustrative photos
Spalled treads and a cracked cheek wall. Broken concrete removed, formed and re-poured, finished to match the walkway.
Mold Remediation · Kanata · 3 days

Musty smell traced to a failed seal at grade. Affected drywall and framing removed under containment, surfaces treated, area dried, and the foundation leak sealed so it stays gone.

Why choose us
Most of our work comes from referrals. Word-of-mouth only happens when homeowners trust the diagnosis, respect the execution, and the invoice matches the written quote. We earn that repeatedly.
How it works
Transparency at every step. Complete structural assessment before any excavation. Written, itemized quote before any work begins. Progress updates during execution. No hidden costs, no surprise invoices.
Tell us what you are seeing. If you can send a photo on WhatsApp, do — it often tells us more than a paragraph.
Free, on site, no sales pitch. We find the water, check the wall, and photograph what we find so you can see it too.
Itemised, with what is included and what is not. If the job does not need doing, we will tell you that instead.
Fixed scope, agreed dates. The site gets put back — graded, swept and tidy — before we invoice.
Service area
City lots, rural properties and everything between. Free on-site assessments anywhere we work.
What customers say
Reviews go here. Set up the Google Business Profile, ask the last ten customers for a review, then paste the profile link into lib/site.js and the real ones will show in this spot.

Free, no obligation
Submit: (1) photos of the issue, (2) your address/neighborhood, (3) a brief description, and (4) your preferred timeline. We read every request ourselves and reply within one business day — often with a price range, always with a free on-site assessment before your final written quote.
Questions
No. Coming out, looking at the problem and giving you a written quote is free, anywhere in our service area.
Range: $800–$35,000+, depending on wall scope. Interior crack injection: ~$800–$3,500 (symptom management). Exterior wall section repair: $8,000–$35,000+ (structural fix). Anyone quoting foundation work over the phone is either guessing or selling you incomplete work. We do a free site inspection, assess structural integrity, then provide a fixed written quote.
Yes — we carry liability insurance and can provide a certificate before work starts. Ask for it; a contractor who cannot produce one should not be on your property.
Most assessments happen within a few days. If water is actively coming into your basement, call rather than fill in the form and we will get to you sooner.
Interior repairs, mold remediation, and emergency leak mitigation: yes, year-round. Exterior work and concrete curing depend on ground temperature and frost depth. If winter conditions mean the repair won't perform properly (concrete won't cure, backfill will heave), we schedule spring completion rather than accept substandard conditions. We'll outline your interim management options (sump pumping, temporary sealing, drainage improvements) so you're not left without solutions during the cold months.
A free on-site assessment takes about thirty minutes and costs you nothing. You will know what is wrong, whether it needs doing now, and what it costs.
