At Zavza Seal, we’re here to educate, protect, and restore. Our mission is to help homeowners and property managers across Suffolk and Nassau counties understand the risks of water and mold damage, and take practical steps to prevent them. If your home has been damaged by a flood, storm, or nor’easter, we’ve got 4 locations across Long Island, Brooklyn, Queens, and the Bronx to serve you.

Here’s how our team can help you recover safely and permanently:
- Water Extraction & Flood Cleanup: We remove standing water fast to stop further damage and prevent structural weakening. Our team uses high-capacity extraction systems to pump out water from basements, crawl spaces, and lower levels safely and efficiently.
- Dehydration & Structural Drying: After the water is gone, we focus on what you can’t see the trapped moisture inside walls, floors, and insulation. We use commercial air movers and dehumidifiers to dry your home completely, reducing the risk of hidden mold growth.
- Water Damage Restoration: From warped floors to damaged drywall, our water damage restoration specialists rebuild and repair what the flood took out. We restore your home to pre-flood condition while coordinating with your insurance provider to make the process as smooth as possible.
- Waterproofing & Encapsulation: To stop future flooding, we install long-term moisture barriers, seal cracks, and encapsulate crawl spaces. Our systems create a dry, healthy foundation that keeps water, humidity, and mold away for good.
- Interior & Exterior Drainage Systems: We design custom drainage systems that move water safely away from your home; inside and out. This includes French drains, sump pumps, and exterior grading solutions that protect your foundation from repeat flooding.
If your property has been affected by the recent storm, don’t wait to take action. Every hour that water sits can increase long-term damage and cost. Zavza Seal’s licensed, local restoration team is ready to help you recover quickly and protect your home before the next storm hits.

What To Do Immediately After Flooding
If your property has taken on water, acting fast can make the difference between cleanup and full reconstruction. Follow these five safety-first steps before or while our certified technicians are on their way:
- Turn Off Power: If it’s safe to reach your breaker, cut electricity to flooded areas to avoid shock hazards.
- Document the Damage: Take photos and videos of every affected area for your insurance claim.
- Call Certified Pros: Our IICRC-certified specialists provide professional flood cleanup and moisture mapping for every class of water intrusion.
- Start Drying Fast: Even an inch of water can raise humidity above safe levels. We use industrial dehumidifiers to bring relative humidity below 50%.
- Prevent Mold Early: Mold spores can begin forming within 24-48 hours. We apply EPA-registered antimicrobial treatments and verify air quality to keep your home safe.
By following these steps, you’ll minimize secondary damage, speed up insurance processing, and create a safer environment for your family until our team arrives.
Our Flood Cleanup Process
Flood damage restoration is a controlled process guided by industry standards and verified drying measurements. At Zavza Seal, every job follows a proven sequence rooted in IICRC and ASTM best practices, ensuring your property is restored safely, efficiently, and completely.
- Assessment & Safety Testing
Before any cleanup begins, we perform a full-site evaluation to determine contamination class, water source, and structural impact. Using moisture meters, thermal imaging cameras, and hygrometers, and ASTM E2128 standards for building envelope testing and moisture penetration measurement, we measure hidden water pockets and airborne humidity. This data helps us create a precise restoration plan that targets every affected area, from the basement floor slab to the attic insulation.
- Water Extraction & Structural Drying
Once the assessment is complete, our team begins rapid water extraction using high-capacity pumps and wet vacuums. Industrial-grade air movers and dehumidifiers then bring your property back to safe moisture levels.
We don’t time anything. We rely on science.
Every phase is tracked with moisture readings until your materials meet dry-time benchmarks established by ASTM E337 and IICRC S500.
Our Target Outcome: Relative humidity below 50%, material moisture content under 16%.
- Sanitization & Deodorization
Floodwater often contains contaminants that can linger long after the surface looks dry. We apply EPA-registered antimicrobial agents to disinfect walls, floors, and furnishings, followed by HEPA air filtration to remove airborne particles and odors. Our deodorization step neutralizes smoke, mildew, and organic odors, restoring clean, breathable air to your home.
- Structural Dry-Out Verification
Once your space feels dry, we verify it’s truly safe and compliant according to IICRC S500 moisture documentation standards for post-restoration certification. Our specialists record final moisture readings and compare them to your pre-flood baselines to confirm clearance. You’ll receive a written report documenting all drying data, including photos, humidity charts, and verification of complete moisture removal, ideal for insurance claims and peace of mind.

What should I do immediately after a flood in my Long Island home?
Turn off power if it’s safe, document all damage for insurance, and call certified flood restoration specialists. Zavza Seal responds quickly across Suffolk County to begin water extraction, drying, and mold prevention. Acting fast can prevent hidden moisture damage, drywall collapse, and long-term mold problems. We’re available now for free flood damage assessments.
How soon can mold start growing after floodwater exposure?
Mold can begin forming within 24 to 48 hours of water exposure. Humidity above 60 percent and soaked building materials create the perfect environment for spore activity. Zavza Seal uses moisture mapping, dehumidification, and EPA-registered antimicrobial treatments to stop mold before it spreads. Schedule an assessment immediately after flooding to reduce long-term risk.
Does Zavza Seal offer free flood damage assessments?
Yes. Zavza Seal provides free flood damage inspections for homes in Bay Shore, Mastic Beach, East Patchogue, Lindenhurst, Fire Island, and nearby towns. Our IICRC-certified technicians assess moisture levels, structural damage, and mold risk. We’ll provide a same-day restoration plan with drying benchmarks, insurance documentation, and next steps for recovery.
What is the flood cleanup process Zavza Seal follows?
Our restoration process follows IICRC S500 and ASTM E2128 standards. First, we assess the site, test for moisture and contamination, then begin high-speed water extraction and structural drying. We apply antimicrobial agents, control odors, and monitor drying progress with daily moisture readings. Final clearance includes a written report and certification.
How can I prevent mold after a flood?
Prevent mold by removing water fast, lowering humidity, and sealing vulnerable areas. Zavza Seal installs sump pumps, crawl space encapsulation, drainage systems, and waterproof membranes to stop future moisture intrusion. We apply EPA-approved antimicrobials after cleanup and verify that all materials are dried to safe levels before restoration begins.
What areas does Zavza Seal serve for flood cleanup?
We provide emergency water removal, drying, and restoration services across Suffolk and Nassau Counties. This includes Bay Shore, Mastic Beach, East Patchogue, Lindenhurst, Fire Island, and all surrounding Long Island coastal zones. Our dispatch system prioritizes high-risk neighborhoods affected by storm surge, flash flooding, and rising groundwater.
Is water damage covered by homeowners insurance?
It depends on the water source. Most insurance covers sudden pipe bursts but not natural flooding unless you have flood insurance. Zavza Seal works directly with insurance adjusters and provides detailed reports with thermal imaging, moisture maps, and dry-time logs to support your claim and speed up approval.
What certifications does Zavza Seal hold for flood restoration?
Zavza Seal is fully licensed and insured in New York State. Our technicians are IICRC-certified in Water Damage Restoration (WRT) and Applied Microbial Remediation (AMRT). We follow ASTM-compliant drying and moisture verification procedures for all flood response work. You receive a documented clearance report with each job.
Can floodwater cause long-term structural damage?
Yes. If left untreated, floodwater can weaken foundations, rot framing, damage subfloors, and trigger mold growth inside walls and insulation. Zavza Seal uses building envelope testing and structural drying to restore integrity. We dry to ASTM and IICRC moisture benchmarks and verify stability before repairs or reconstruction begin.
How fast can Zavza Seal respond to flooding in my area?
