Who We Are: A Licensed Waterproofing Crew in Lakeville
Arrow Tight Waterproofing exists because too many property owners in Lakeville were getting patchwork fixes instead of real diagnosis. Our crews are licensed in MN, carry full liability coverage, and are trained to find the actual water path before recommending anything.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Lakeville β no subcontractors, no handoffs, no one new showing up halfway through.
Every technician completes ongoing training as materials and methods evolve β 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 MN 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 β never subcontracted out
Warning Signs
How to Tell If your Lakeville property Needs Attention Now
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 Lakeville.
01
Efflorescence on Basement Walls
We see this most often on walls that look completely dry to the touch β the salt deposit is evidence of past water movement, not current dampness.
02
A Musty Smell That Won't Go Away
Persistent musty odor almost always traces back to elevated humidity or an active leak feeding mold growth somewhere you can't see.
03
Cracks Along the Wall-Floor Joint
The cove joint is the single most common water entry point in basements β staining or gaps there usually mean hydrostatic pressure is pushing water in.
04
A Sump Pump That Never Stops Running
We treat constant cycling as an early warning, not a normal condition β the pump working overtime today is the pump failing sooner than expected.
05
Bowing or Leaning Foundation Walls
A wall that's no longer plumb is telling you the soil outside is pushing harder than the wall was built to resist.
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
What Arrow Tight Waterproofing Handles in Lakeville
From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Lakeville.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we β our emergency line in Lakeville is answered live, 24 hours a day, with crews dispatched to stop the immediate entry point first.
We carry the equipment needed to control an active situation immediately, then scope the permanent fix once the emergency is under control.
Residential waterproofing in Lakeville 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.
Commercial foundations in Lakeville carry different risk than residential ones β larger footprints, tenant liability, and often tighter access β and our crews scope and schedule around that.
Commercial jobs get the same commercial-grade materials as our residential work β nothing scaled down because the client is a business instead of a homeowner.
Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Lakeville showing signs of settlement or lateral pressure.
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.
Failed or undersized sump pumps are one of the most common reasons a previously working system suddenly floods, and we treat pump sizing as its own diagnostic step, not an afterthought to drainage work.
We also correct discharge line routing and grading as part of any pump job, since a poorly graded discharge line often just recirculates water back toward the foundation.
These aren't marketing lines β 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 Lakeville isn't driving hours to get there.
Satisfaction Backed in Writing
Warranty documentation is registered to the property address, so it transfers automatically if you sell, without needing to track us down for paperwork.
Commercial-Grade Materials, Every Time
We install the same membrane specification, pipe schedule, and pump ratings on residential jobs that commercial contracts require β never a downgraded consumer-grade substitute.
Diagnosis Before Recommendation
A diagnosis-first approach costs us more time per estimate, but it's the reason our repeat-callback rate is a fraction of the industry average.
Our Process
What to Expect When You Call Arrow Tight Waterproofing
01
Call or Request an Inspection
There's no charge for the call or the inspection that follows, so there's no downside to getting a second opinion even if you've already spoken with another contractor.
02
On-Site Diagnosis
We document every visible entry point and pressure indicator during the visit β this is what the eventual proposal is built around.
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
Our crew completes the approved scope, verifies the fix with post-install moisture readings, and hands you written warranty documentation registered to the property.

"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.Exactly the level of service we expected."

"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.Would recommend them without hesitation."

"Appreciated that they didn't just sell us a package. The inspection actually found the real problem β a bowing block wall β and the carbon fiber reinforcement plus crack injection fixed it properly instead of just sealing the surface.That's the kind of fix that actually holds up."

"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 β no more constant cycling, and it's kept up with two heavy storms since.That's the kind of fix that actually holds up."

"We're a small property management company and needed drainage work done across three units without disrupting tenants.

FAQ
Waterproofing Frequently Asked Questions
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 β 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.
If interior fixes haven't held or the wall shows active exterior deterioration, exterior waterproofing is usually the better long-term answer β we'll tell you honestly which applies.
We document every job with photos and moisture readings you can submit for any claim, regardless of what your policy ultimately covers.
Timeline depends entirely on scope β we give you a written schedule estimate as part of the proposal so there's no ambiguity going in.
Always an in-person inspection β we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
Warranty terms are documented and registered to the property address, with a clear process for filing a service claim if anything comes up.
Coverage extends across Lakeville β call +1-866-476-1348 to confirm your specific address, though it's almost certainly within our service area.
For the initial inspection, yes β we need access to the affected area and it helps to walk through what we're seeing together, though the visit is usually under an hour.
A patch treats the visible symptom β a caulked crack, a coat of sealant β without addressing why water found that path in the first place, so the same issue often resurfaces nearby.
We're not a public adjuster, but we document every job with dated photos and moisture readings formatted for insurance submission, which you can include with your own claim.
