Who We Are: A Licensed Waterproofing Crew in Ottawa
We started Arrow Tight Waterproofing after years of watching homeowners get sold vague 'waterproofing packages' that never named the actual problem. Every technician we send in Ottawa is licensed, background-checked, and trained to diagnose before quoting — not the other way around.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Ottawa — no subcontractors, no handoffs, no one new showing up halfway through.
Every technician completes ongoing training as materials and methods evolve — the polyurethane injection resin we use today isn't the same formulation the industry relied on ten years ago, and neither is our crew's training.
IICRC-certified technicians on every job, no exceptions
licensed in OH with full liability and workers' comp coverage
Thermal imaging and calibrated moisture readings before every quote
Written, transferable warranty on all completed systems
Direct-employee crews — never subcontracted out
Warning Signs
Six Warning Signs You Shouldn't Ignore
Waiting until you see standing water means you've already missed the cheaper fix. These are the early signals our crews are trained to catch in Ottawa.
01
Efflorescence on Basement Walls
White powdery buildup on a foundation wall means water has been passing through it, even if the surface looks dry today.
02
A Musty Smell That Won't Go Away
Odor alone rarely tells you the source, but it's a reliable sign something needs a real moisture inspection rather than an air freshener.
03
Cracks Along the Wall-Floor Joint
This is the exact spot our technicians check first on every basement inspection, because it tells us more about the pressure situation than almost anywhere else.
04
A Sump Pump That Never Stops Running
A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.
05
Bowing or Leaning Foundation Walls
Measuring wall deflection with a level is one of the first things we do on any inspection where bowing is suspected, since the degree of lean changes the recommended fix.
06
Rust Stains Bleeding Through Concrete
This sign often gets dismissed as cosmetic, but it points to water reaching structural steel, which is a different severity than surface dampness.
07
Peeling Paint or Soft Drywall Near the Floor
By the time drywall is visibly damaged, the moisture behind it has usually been present for weeks or months already.
08
Cold, Damp Floors Above a Crawl Space
Homeowners often replace or service their HVAC system first, only to find the actual cause was ground moisture migrating up through an unsealed crawl space.
Core Services
Complete Waterproofing Solutions, in Ottawa
We don't sell a single fixed package — every property in Ottawa gets a scope built around what our inspection actually finds.
01
Emergency Water Intrusion Response
When water is actively entering a property in Ottawa, our first priority is stopping the intrusion, then extracting standing water before secondary damage sets in.
Every emergency truck carries submersible pumps, temporary sump units, and crack-sealing materials, so most active leaks can be stabilized on the first visit.
Residential waterproofing in Ottawa covers everything from a single crack injection to a full-perimeter drainage retrofit, scoped after a real inspection.
Every residential install includes post-job moisture verification, so you have documented proof the system is working, not just our word for it.
For property managers in Ottawa, we coordinate around occupied units and business hours, minimizing disruption while still delivering a full waterproofing scope.
We provide the same written, itemized proposals for commercial clients as residential ones, with the added documentation many property managers need for ownership or insurance records.
When a foundation issue is structural rather than purely a water problem, we bring in the crack-classification and reinforcement expertise that basic waterproofing crews don't carry.
We're upfront when a problem needs structural engineering input beyond what waterproofing alone can fix, rather than selling a repair that won't hold.
A waterproofing system is only as reliable as the pump moving water out of it — we size, install, and upgrade sump systems in Ottawa to match actual groundwater volume rather than defaulting to whatever's in stock.
Battery backup and monitored alarm options are available on every pump we install, so a power outage during a storm doesn't leave the system unprotected.
These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.
Upfront, Itemized Pricing
Pricing surprises are the single biggest complaint we hear about competitors, so we built our proposal process specifically to eliminate them.
Fast Local Dispatch
We don't run a single centralized dispatch queue; regional staging means the crew reaching you in Ottawa isn't driving hours to get there.
Satisfaction Backed in Writing
If something about the completed work doesn't meet the scope we agreed to, we return and correct it under the warranty terms, in writing.
Commercial-Grade Materials, Every Time
Our sump pumps are cast iron, our drain tile is schedule 40 PVC, and our membranes are rated for sustained hydrostatic pressure — not hardware-store equivalents.
Diagnosis Before Recommendation
Our technicians document the actual water path and pressure source before recommending a fix, so you're paying for the right repair the first time.
Our Process
What to Expect When You Call Arrow Tight Waterproofing
01
Call or Request an Inspection
Reach our dispatch line in Ottawa any time — we'll ask what you're seeing and schedule a free on-site inspection, often within 24 hours.
02
On-Site Diagnosis
Expect the inspection itself to take 45 to 90 minutes depending on property size and how many areas need checking.
03
Written, Fixed-Price Proposal
Review the proposal at your own pace; we don't pressure same-visit sign-off, though we can often start within days once approved.
04
Installation & Warranty Documentation
Once the system is installed and tested, you get warranty paperwork that transfers with the property if you ever sell.

"Had a cove joint leak that two other companies just patched without explaining why it kept happening. Arrow Tight Waterproofing's technician showed me the moisture readings and traced it to hydrostatic pressure, then installed drain tile that's held through every storm since.That's the kind of fix that actually holds up."
R. — Homeowner, Ottawa
★★★★★
"Called at 11 PM with active water coming in during a storm. Live person answered immediately, crew was on-site within the hour, and they had a temporary pump running before starting the real diagnosis.That's the kind of fix that actually holds up."
K. — Emergency Client, Ottawa
★★★★★
"We manage a small multi-unit building and needed the work scheduled around tenants. They coordinated everything cleanly and the commercial-grade membrane they used has zero callbacks two years later.That's the kind of fix that actually holds up."
T. — Property Manager, Ottawa
★★★★★
"Appreciated that they didn't just sell us a package. The inspection actually found the real problem — a bowing block wall — and the carbon fiber reinforcement plus crack injection fixed it properly instead of just sealing the surface.Exactly the level of service we expected."
M. — Homeowner, Ottawa
★★★★★
"Sump pump had been cycling nonstop for weeks before we called. They correctly diagnosed it as undersized for our actual water table and upgraded it — no more constant cycling, and it's kept up with two heavy storms since.Would recommend them without hesitation."
D. — Homeowner, Ottawa
★★★★★
"We're a small property management company and needed drainage work done across three units without disrupting tenants. Arrow Tight Waterproofing scheduled around occupied hours, communicated clearly with residents, and the itemized invoice matched the original proposal exactly.Exactly the level of service we expected."
L. — Property Manager, Ottawa
FAQ
Straight Answers About Waterproofing
Standard inspections are typically scheduled within a few days of your call; active emergencies get same-day priority dispatch in most of our coverage area.
Yes — every job gets a written, itemized proposal after a real on-site inspection, and that number is what you're invoiced, not an estimate that grows once work starts.
Our emergency line is answered live 24/7, and crews carry equipment for immediate water extraction, temporary sump deployment, and active crack sealing on the first visit.
Interior drainage manages water after it enters at the wall-floor joint; exterior waterproofing stops it from reaching the wall at all. Our inspection determines which fits your specific situation.
Gradual groundwater seepage is typically treated as a maintenance issue and excluded, while sudden events like burst pipes are often covered — check your specific policy language.
Crack injection is usually a few hours; interior drain tile runs 1 to 3 days depending on perimeter footage; full exterior excavation can run 2 to 5 days depending on depth.
Always an in-person inspection — we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
Yes — every completed system includes a written warranty that's transferable if you sell the property, not just a verbal assurance.
Coverage extends across Ottawa — call +1-866-476-1348 to confirm your specific address, though it's almost certainly within our service area.
For the actual repair, it depends on scope — interior work often doesn't require you to be present for the full job, while we'll coordinate access details with you directly for anything involving excavation.
A patch treats the visible symptom — a caulked crack, a coat of sealant — without addressing why water found that path in the first place, so the same issue often resurfaces nearby.
Some clients ask us to speak directly with their adjuster about scope and materials, and we're glad to when it's useful for a claim already in progress.
