Who We Are

We built Arrow Tight Waterproofing on a simple premise: waterproofing work in Somerville should be diagnosed correctly the first time, not sold as a guess and revisited three times.

Every technician on our roster is Waterproofing-certified and licensed in NJ, trained specifically in hydrostatic pressure diagnosis, drain tile installation, and structural crack classification — not general handyman work rebranded as waterproofing.

A basement filling with water doesn't wait for a convenient appointment, so our dispatch model is built around same-day response for active seepage in Somerville.

We believe a homeowner should be able to see the evidence behind a recommendation, not just take our word for it — every diagnostic visit comes with documented findings you can keep.

Warning Signs You Shouldn't Wait On

Catching these signs early usually means a smaller repair bill and a lot less disruption to your home.

A musty smell that returns no matter how often you clean the basement.

White, chalky staining on block or poured concrete walls — a mineral deposit called efflorescence.

Sticking doors on the ground floor are one of the more overlooked signs of a shifting foundation.

Visible cracks in the foundation wall, whether hairline or wider stair-step patterns.

If a heavy storm reliably means a wet spot on the basement floor, that's a pattern, not bad luck.

An overworked sump pump is a warning sign in itself — it's compensating for something upstream.

Bowing or leaning foundation walls, even subtle ones you can check with a level.

A hygrometer reading that stays above 60% no matter how much you run a dehumidifier usually points to an active intrusion source.

If metal items in your basement are corroding faster than they should, ambient moisture is almost certainly the cause.

Core Waterproofing Solutions in Somerville

From emergency response to permanent structural fixes, here's the full range of work our crews handle in Somerville.

24/7 Emergency Waterproofing experts in Somerville, NJ

Emergency Water Extraction & Stabilization

Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. We follow extraction with a full moisture survey so the permanent fix addresses the actual source, not just the visible symptom.

Interior Drain Tile & Sump Systems

A perimeter drain tile channel installed below the slab intercepts groundwater before it can reach your floor, routing it to a properly sized sump basin and pump. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.

Foundation Crack Injection

Non-structural cracks respond well to polyurethane or epoxy injection depending on whether water is actively present and whether the crack is still moving. Photos and measurements are logged before and after every injection for your records.

Exterior Excavation & Membrane Application

This is the most thorough fix available and typically carries the longest service life, though it's not always necessary depending on what the interior diagnostic finds.

Crawl Space Encapsulation & Vapor Control

We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.

Sump Pump Installation & Battery Backup

We calculate your pit's actual inflow rate before recommending pump horsepower, since an undersized pump is one of the most common causes of preventable flooding. Cellular notification add-ons alert your phone directly if the system is ever triggered.

Wall Vapor Barrier & Structural Reinforcement

For walls showing early bowing alongside seepage, carbon fiber straps or steel wall anchors can arrest further movement before it becomes a bigger structural concern. We explain the engineering rationale before recommending any wall reinforcement work.

Why Somerville, NJ Homeowners Choose Arrow Tight Waterproofing

Five things that actually separate a specialized Waterproofing crew from a general contractor with a truck and a sump pump on hand.

It's easy to promise fast, honest Waterproofing service in an ad — the real test is whether that promise holds up once a technician is actually standing in your basement.

1

Same-Day Response for Active Intrusion

A basement actively taking on water moves to the front of the schedule — most Somerville, NJ service areas see a technician within hours, not days.

2

Written, Itemized Pricing — No Surprises

You'll know the exact cost before work starts — no hourly guessing games, no mid-job upcharges for what a proper inspection should have caught.

3

Diagnosis Before Recommendation, Always

Technicians are trained to identify the real entry point, not just treat the most visible symptom.

4

Licensed Specialists, Not General Contractors

Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.

5

Written Warranty on Every Installed System

We stand behind installed systems with documented warranty terms included in your quote, not a verbal promise that's hard to pin down later.

How a Waterproofing Project Actually Works

Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.

1

Call & Triage

One call connects you to local dispatch, not a national call center — they'll ask a few questions to understand what you're seeing and prioritize accordingly.

2

On-Site Diagnostic Visit

The diagnostic visit maps your full basement or crawl space perimeter before any repair is recommended.

3

Written Quote & Scheduling

Pricing reflects exactly what the diagnostic found, not a generic package.

4

Installation & Verification

A written warranty and, where relevant, a post-storm follow-up check come standard with every completed installation.

Frequently Asked Questions

High-intent questions we hear most from Waterproofing customers across Somerville, NJ.

How fast can a Waterproofing technician arrive in Somerville, NJ?+
Active water intrusion moves to priority scheduling, and most Somerville, NJ service areas see a technician within hours of the call.
Do you provide upfront, flat-rate pricing?+
You'll know the full cost before work starts; nothing gets added mid-job without your sign-off first.
Will interior drain tile actually stop the water, or just hide it?+
It's a proven, code-recognized method for managing hydrostatic pressure, not a cosmetic fix that just moves the problem out of sight.
Do I need exterior excavation or can interior work solve it?+
We evaluate both approaches during the diagnostic and recommend whichever solves the actual entry point with the least disruption.
What's the difference between a hairline crack and a structural one?+
A hairline crack is typically under an eighth of an inch and stable — a good candidate for injection. A structural crack shows displacement or is still widening and needs engineering evaluation first.
Is waterproofing work covered by a warranty?+
Warranty terms are included in your written quote before work begins, so there's no ambiguity about what's covered.
How long does a typical installation take?+
Interior drain tile installations are usually completed in one to two days depending on perimeter length.
Do you work on older homes with existing foundation issues?+
Yes, older foundations are some of the most common jobs we handle, and our diagnostic accounts for aging materials and previous repair attempts.
What causes a basement to flood in the first place?+
Hydrostatic pressure from groundwater, poor exterior grading, a failed sump pump, or a combination of all three are the most common causes we diagnose.
Can you help with insurance documentation after a flood?+
We document extraction and mitigation work with photos, moisture readings, and timestamps you can include with a claim.
Do you offer emergency service outside business hours?+
Yes, emergency dispatch operates continuously for active flooding and failed sump pumps, including nights and weekends.
Can you work with my homeowner's insurance claim directly?+
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.
Do I need to be home during the diagnostic visit?+
Being present lets you see the moisture readings and camera footage firsthand rather than getting a secondhand summary.
What's the first sign I should call about, even if it seems minor?+
Efflorescence — that white chalky residue on concrete — is an easy one to miss but worth addressing early.
Do you offer any kind of maintenance check after installation?+
We're glad to do a post-storm follow-up check after a significant rain event to confirm the system is performing as designed.
Will waterproofing work lower my homeowner's insurance premium?+
Some insurers do offer discounts for documented flood mitigation work — we can provide the paperwork, though the discount itself depends on your specific policy and carrier.
Do you offer financing for larger projects?+
Financing availability depends on project scope; smaller single-system jobs are usually straightforward flat-rate, while larger combination repairs sometimes qualify for financing.
How do I know if I actually need waterproofing or just better gutters?+
If water is reaching your foundation wall itself, gutters alone usually aren't enough; we'll tell you honestly if a smaller fix like downspout extension would solve it.
Do you guarantee your work in writing, not just verbally?+
Yes, every installed system — drain tile, sump, injection, exterior membrane — comes with written warranty terms included in your quote before work begins.
What should I do right now if water is actively coming in?+
Move valuables away from the affected area if it's safe to do so, then call +1-866-476-1348 so extraction can begin as soon as a crew arrives.
