Wet Basement Problems We Solve in Outer Comstock
3 problems account for most of the calls we take on these streets, and telling a sealing problem from a pressure problem decides which repair yours needs.
- 1 Water slowing and soaking in Where the grade eases the flow stops moving and enters the ground instead, raising the table around the foundation.
- 2 Cove joint seepage after the thaw begins Water arriving from uphill and soaking in shows at the floor edge rather than the wall face.
- 3 Driveways sloping toward the house Long driveways on the grade deliver runoff to the foundation unless the pitch is corrected.

Beyond Waterproofing
Our Related Services
A dry basement rarely comes from one product. These 3 services sit alongside our basement waterproofing work and often form part of the same project, quoted and warrantied together.
Crawl Space Encapsulation
A 20-mil reinforced vapor barrier sealed to the walls and piers, rim joists insulated and humidity held under 55%, turning a damp dirt crawl space into conditioned, storable space.

The Ground Under Your House
Why Outer Comstock Basements Flood
3 conditions put water in a basement here. Which one is driving yours decides the
system you need, and the free inspection settles it in 40 minutes.
Flow Slowing at the Base of the Hill
Water leaving the 150 ft (46 m) grade above slows on the flatter ground here and soaks in rather than passing through.
A Rising Table Through the Thaw
Soaking water raises the local table around the foundation, so entry shifts from the wall to the cove joint.
Driveways Pitched Toward the Foundation
A driveway falling toward the house delivers meltwater directly to the wall for the length of the thaw.
Wait or Act, Side by Side
Risks of Delaying vs. Benefits of Waterproofing Now
Water damage moves in steps, not gradually. A basement that leaks in one spot this March
leaks in three next March, and above 60% humidity the EPA expects mold within days (opens in a new tab) , not seasons. Below are the 5 things that keep happening if you wait, set against the 5 that
change once the water is under control. The nine signs a basement shows first tell you which step you are on.
Risks of Delaying Waterproofing
Putting off basement waterproofing in Syracuse creates 5 bigger problems:
- Freeze-thaw widens every entry point each winter, so the leak never stays the size it is now
- Mold and mildew establish above 60% humidity, then spread into framing, insulation and stored boxes
- Frost pressure keeps moving the foundation wall until structural reinforcement becomes necessary
- A finished lower level becomes demolition, with drywall, flooring and trim all coming out
- Homeowner policies exclude gradual seepage, so the full repair bill lands on you
Benefits of Waterproofing Now
A properly built waterproofing system delivers 5 long-term advantages:
- Dry square footage you can finish, furnish and use through all 4 seasons
- Relative humidity held under 50%, the level at which mold and mildew cannot establish
- Hydrostatic pressure relieved before it moves a foundation wall out of plumb
- Lower heating bills once cold, damp air stops rising through the house
- A lifetime transferable warranty that becomes a selling point at closing
The inspection is free and commits you to nothing. Finding out yours is a small fix counts as a good outcome, and it happens more often than most homeowners expect.
Find Out Where I Stand How The Problem Gets Solved
Our Basement Waterproofing Solutions
Water enters a Syracuse basement 3 ways: through openings, under hydrostatic pressure (opens in a new tab) , and as vapor. Each route needs its own answer, and most homes here need at least two of them.
Sealing is crack injection , vapor control
is crawl space encapsulation , and
where the framing underneath has already gone soft it is crawl space repair first.
Seal Every Entry Point
The problem
Water entering through foundation cracks, cold joints and porous block
A foundation leaks only where a path exists. We locate every one of them, meaning cracks, cold joints, tie-rod holes and the cove where wall meets slab, then close each path through the full thickness of the wall instead of coating the face.
- Resin fills the void completely, leaving no edge for water to find
- Cured repair holds more strength than the concrete around it
- No excavation and no landscaping damage on 9 out of 10 jobs
- Wall stays paintable and ready to finish the same day
Lifetime no-re-leak guarantee
Relieve The Water Pressure
The problem
Hydrostatic pressure pushing groundwater up through the slab
No sealant holds back a standing column of water. Relief works instead. An interior drain tile system set at footing level gives that water an easier route, carrying it below the floor rather than letting it force a way through.
- Basement flooding stops for good instead of being mopped up each March
- Installs on frozen, saturated ground, so the work happens mid-winter
- Filter fabric and corner clean-outs keep the drainage system clear for decades
- Leaves the basement dry enough to frame, insulate and live in
Lifetime transferable warranty
Control The Moisture In The Air
The problem
Damp ground and humid air feeding mold, odor and cold floors
Liquid water accounts for half the problem. Bare soil evaporates continuously and the stack effect carries that air straight into your living space. A vapor barrier seals the ground, rim joists get insulated, and a dehumidifier holds humidity below the level mold needs.
- Relative humidity held under 55% through all 12 months
- Musty smell in the rooms above clears within days
- Ground-floor rooms measure 4 to 6°F (2 to 3°C) warmer in winter
- Space turns into clean, lit, genuinely usable storage
25-year liner warranty
Which of the 3 your house needs gets decided on site, not over the phone, and the inspection that decides it costs nothing.
Book a Free Inspection How It Works
Our Basement Waterproofing Process
Step 1: Free On-Site Inspection & Diagnosis
We start with a full inspection of your basement, covering moisture mapping, a grading and downspout review, and a hose test that shows exactly where water enters. It takes 45 minutes and carries no obligation.
Step 2: Written Quote & Custom Solution Plan
From the findings we design a system for your foundation rather than a template. You receive a fixed price in writing, materials named by brand, and the change-order policy stated before you sign.
Step 3: Installation (Typically 2 to 4 Days)
Our own certified crew installs the system, with the person who quoted the job on site. Containment goes down first, spoil leaves by bucket rather than slurry, and the work area gets swept every evening.
Step 4: Final Walkthrough, Cleanup & Warranty
We flood-test the system in front of you, then hand over written moisture readings taken before and after. Your lifetime transferable warranty gets registered before the crew leaves the driveway.
Standing Behind It
Our Warranty & Guarantee
A warranty carries only as much weight as the detail written into it. Ours names the
treated area, covers the labor, and moves with the house when you sell. The full warranty and financing terms are published in full rather than summarized on request, which is what New York State consumer protection (opens in a new tab) tells you to look for. We would rather build a system that lasts than write an exclusion
that protects us.
- Printed in plain language on the proposal you sign, not mailed as a separate document later
- Names the specific area treated, so no argument about scope arises years afterward
- Covers labor alongside materials, which most contractor warranties quietly exclude
- Transfers to the next owner once at no cost, using a one-page form at closing
- Includes free annual system service for as long as you own the house
Lifetime
Basement waterproofing, transferable
Covers water entry through the treated area, labor as well as materials. It transfers once to the next owner at no cost, which removes a negotiating point that costs sellers thousands at closing.
Lifetime
Crack repair, no re-leak
If an injected crack leaks again along the same line, we come back and reinject it at no charge. Cured resin holds more strength than the concrete around it, so the repair outlasts the wall.
25 years
Crawl space liner
Manufacturer material warranty on the 20-mil reinforced vapor barrier, plus our own workmanship guarantee on every seal, termination and section of rim-joist insulation.
10 years
Crawl space structural work
Covers joists, girders, sill plates and support piers. We re-level free of charge if a supported span moves at any point inside the 10 years.
32 Years Under Syracuse Homes
Why Outer Comstock Homeowners Choose Us
Choosing a contractor in Outer Comstock comes down to 2 questions: is the problem still solved in 10 years, and is the company that promised it still answering the phone. We have been answering since 1994.
32+ Years Under Syracuse Homes
Since 1994 we have waterproofed 9,800 properties across the city of Syracuse. We have already worked in whatever sits under your house, including glacial lake clay on the Valley floor, raised street fill downtown, and pre-war rubble footings on Tipperary Hill.
Lifetime Transferable Warranty
Every waterproofing system carries a lifetime warranty against water entry through the treated area, covering labor alongside materials. It transfers to the next owner, which turns it into a selling point rather than a filed receipt.
Diagnosis Before Proposal
Test pits, moisture mapping and a hose test come before any price gets quoted. We cancel proposals regularly once the real fix turns out to be a downspout extension. Selling work nobody needs is how a contractor runs out of referrals.
Certified, Employed Crews
No subcontractors and no day labor. Every technician is an IICRC-certified employee, background-checked, uniformed and trained on our own systems. The person who quoted the job stands on site while the crew builds it.
What Outer Comstock Is Built On
The Ground and the Foundations in Outer Comstock
Housing stock and ground conditions decide the system, and both change from one Syracuse
neighborhood to the next.
The Housing Stock
Outer Comstock holds 1910 to 1935 colonials and four-squares on poured walls, larger and better built than the rental stock north of it. Basements run 8 ft (2.4 m) and many remain unfinished.
The Ground Underneath
The neighborhood sits on the tail of University Hill where the grade eases. Water slows here, which means it soaks in rather than running past, and the table rises accordingly.

- Broad Street

Answers First
Outer Comstock Basement Waterproofing Questions
Straight answers about cost, timing, warranty and what actually causes water in a
Syracuse basement. Still unsure? Ask us directly, we would rather talk it through than
have you guess.
Water shows at the floor edge because it is under the slab rather than passing through the wall. That is pressure from a risen water table and it needs relief, not sealing.
Pour a bucket of water at the top of the driveway and watch where it runs. If it moves toward the house rather than the street, the pitch is the problem.
Yes, unfinished basements are easier and cheaper to fix. Nothing has to come out first, the evidence is visible, and the crew works directly against the wall.
