Arrow Tight Waterproofing diagnoses the real cause before quoting anything — thermal imaging, moisture readings, and a written fixed price in Prospect.
📞 Call Now — Free EstimateWe 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 Prospect is licensed, background-checked, and trained to diagnose before quoting — not the other way around.
We've built our reputation in Prospect on jobs that don't need a second visit. That means slower quoting sometimes, since we're inspecting properly instead of estimating from a driveway conversation, but it also means fewer callbacks.
We keep detailed job records for every property in Prospect we've serviced, which means if you call back in three years with a question about your system, we can pull the exact specs of what was installed rather than starting from scratch.

Most foundation failures don't start as floods — they start small, and they're easy to miss until the damage compounds. Here's what our technicians look for on every inspection in Prospect.
We see this most often on walls that look completely dry to the touch — the salt deposit is evidence of past water movement, not current dampness.
Odor alone rarely tells you the source, but it's a reliable sign something needs a real moisture inspection rather than an air freshener.
Cracking where your floor meets the foundation wall is rarely cosmetic; it's typically the first visible sign of pressure building against the wall.
A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.
A wall that's no longer plumb is telling you the soil outside is pushing harder than the wall was built to resist.
Rust streaks mean water has reached embedded rebar or metal lath and started oxidizing it — a sign moisture has penetrated deeper than the surface.
Paint and drywall absorb moisture vapor before liquid water ever becomes visible, so bubbling or soft spots near the baseboard are an early-stage signal, not a late one.
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.
We don't sell a single fixed package — every property in Prospect gets a scope built around what our inspection actually finds.

When water is actively entering a property in Prospect, our first priority is stopping the intrusion, then extracting standing water before secondary damage sets in.
We carry the equipment needed to control an active situation immediately, then scope the permanent fix once the emergency is under control.
📞 Get a Free Quote →For homeowners in Prospect, we install interior drain tile, sump systems, and crawl space encapsulation sized to your property's actual groundwater load — not a one-size package.
We size every residential system — pump horsepower, pipe diameter, gravel bed depth — to your specific property rather than a generic template.
📞 Get a Free Quote →Commercial foundations in Prospect carry different risk than residential ones — larger footprints, tenant liability, and often tighter access — and our crews scope and schedule around that.
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.
📞 Get a Free Quote →Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Prospect 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.
📞 Get a Free Quote →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.
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.
📞 Get a Free Quote →These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.
Pricing surprises are the single biggest complaint we hear about competitors, so we built our proposal process specifically to eliminate them.
Response time isn't an afterthought for us — it's a scheduling metric we track and staff around, not just a marketing line.
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.
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.
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.
Reach our dispatch line in Prospect any time — we'll ask what you're seeing and schedule a free on-site inspection, often within 24 hours.
Expect the inspection itself to take 45 to 90 minutes depending on property size and how many areas need checking.
If the proposal includes options — say, interior versus exterior drainage — we'll walk through the tradeoffs so you're deciding with full information.
We also walk you through basic maintenance for whatever was installed, so you know what to check twice a year to keep the system performing as designed.
Free on-site inspection, written estimate, no obligation. We answer 24/7.

"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."
"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."
"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.Exactly the level of service we expected."
"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."
"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."
"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.That's the kind of fix that actually holds up."
We built our coverage in Prospect around regional crew staging rather than one central office, which keeps dispatch times shorter across the footprint we serve.
Call +1-866-476-1348 to confirm coverage for your specific address — given our regional staging in Prospect, it's very likely within our service area.
Whether your property in Prospect has a finished basement, an unfinished crawl space, or a slab foundation, our crews carry the equipment and training to assess and quote all three foundation types on the same visit.
If you're unsure whether your address falls within our service footprint, the fastest way to find out is simply calling +1-866-476-1348 — dispatch can confirm coverage on the spot.
