Watch Out for Storm Chasers After Major Storms

When severe weather hits Long Island, the damage doesn’t just bring out insurance adjusters and cleanup crews,  it attracts storm chasers too. These are out-of-town contractors who follow major storms, offering quick fixes and “too-good-to-be-true” prices. They often disappear just as fast, leaving behind unfinished or substandard work that fails within months.

Protect yourself and your investment by knowing what to look for before signing any contract.

Common Warning Signs of Storm Chaser Contractors

• No Local Address or License Number: If the contractor can’t show a valid New York State license or local business registration, walk away.
• High-Pressure Sales Tactics: Anyone pushing you to “sign today” or “lock in before inspectors arrive” is not acting in your best interest.
• Unmarked or Out-of-State Vehicles: Legitimate restoration companies serving Long Island should have branded trucks, not rental vans or paper logos.
• Cash-Only or Large Upfront Payments: Reputable contractors never demand full payment before work begins, especially after a disaster.
• No Written Estimate or Warranty: Storm chasers avoid putting things in writing because they don’t plan to be around when problems resurface.
• Lack of References or Online Presence: A quick Google search can expose fly-by-night operations. Look for consistent reviews, photos, and a verifiable track record.

Smart Questions to Ask Before Hiring Any Storm Damage Contractor

1. Are you licensed and insured to perform storm damage repair in New York State?
2. Do you have an established office or crew based on Long Island?
3. Can you show photos or references from recent local storm repair projects?
4. What national standards (FEMA, IICRC, ASTM, EPA) do you follow for your restoration work?
5. Do you provide a written estimate, project timeline, and warranty before work starts?
6. How do you ensure that mold prevention and waterproofing are included in the repair process?
7. Who supervises your crews, and how long have they worked for your company?
8. What happens if I notice new damage or leaks after the job is completed?

• Water Removal Services: Our water removal services extract standing water fast to prevent mold and structural decay. Using high-capacity pumps and IICRC-certified drying equipment, we remove moisture from every affected area — floors, basements, and crawl spaces included.
• Waterproofing Services: We protect your property against repeat flooding through our waterproofing services. From foundation sealants and sump systems to perimeter drainage, we design permanent waterproofing systems built for Long Island’s storm conditions.
• Mold Remediation Services: Moisture breeds mold, and fast. Our mold remediation services identify, remove, and prevent mold using EPA-approved antimicrobial agents and air filtration. We restore healthy indoor air and stop future outbreaks at the source.

• Structural Repair Services: Storms can weaken walls, piers, and foundations. Our structural repair services stabilize compromised areas with injection grouting, re-anchoring, and reinforcement techniques that meet ASTM and ACI standards for long-term safety.
• Structural Drying Services: Our structural drying services go beyond surface cleanup. We use thermal imaging and commercial-grade dehumidifiers to dry building materials to safe moisture levels — preventing hidden rot and warping that can appear weeks later.
• Air Purification & Odor Removal Services: After a flood, lingering odors and airborne contaminants are more than unpleasant; they’re unhealthy. Our air purification and odor removal services use HEPA filtration and ozone treatments to eliminate bacteria, smoke, and mildew smells permanently.

Our Proven 5-Step Storm Damage Recovery Process

Storm damage recovery isn’t just about showing up with fans and pumps, it’s about having a step-by-step system that’s built to fix the damage and prevent it from happening again. At Zavza Seal, our process follows nationally recognized engineering and safety standards, so you get real results that last.

1. Initial Damage Assessment & Moisture Testing

We begin with a full property inspection, checking for visible and hidden damage caused by flooding, wind, or foundation shifts. Using advanced moisture meters, we scan walls, floors, and crawl spaces for elevated levels of dampness. Even if things “look dry,” we test for water that’s been absorbed deep into your structure, because hidden moisture is the number one cause of mold and rot.

We follow: ASTM D1586 and moisture content readings (we target 16% or lower to prevent microbial growth).

2. Water Removal & Structural Drying

Next, we bring in high-capacity pumps and drying equipment to quickly extract standing water and dehumidify the affected areas. Our crews create a customized dry-out plan based on your building materials, insulation type, and air circulation. This step is critical to stop mold before it starts and prevent structural weakening from prolonged moisture exposure.

We follow: IICRC S500 drying standards, ensuring your property is restored to safe moisture levels.

3. Repair & Reinforcement

Once the structure is dry, we shift to repairing what’s been damaged. This may include injecting cracks in your foundation, stabilizing footings, repairing masonry, or reinforcing walls. We use structural-grade adhesives and bonding agents to strengthen compromised areas, giving your home or business a solid base for the future.

We follow: ASTM C881 and ACI 355 standards for structural bonding and load-bearing reinforcement.

4. Mold Prevention & Sanitization

Floodwater can leave behind dangerous mold and bacteria. We apply EPA-registered disinfectants, use air scrubbers and HEPA vacuums to clean the air, and seal affected surfaces to prevent spores from spreading. Every job includes a mold risk assessment and targeted remediation strategies if needed.

We follow: EPA Mold Prevention Guide and IICRC S520 protocols for safe, effective mold control.

5. Permanent Waterproofing & Resilience Upgrades

Finally, we help protect your property from future storms. That includes installing sump pumps, encapsulating crawl spaces, upgrading drainage systems, and applying waterproof coatings to foundations and walls. These solutions are tailored to your property and local flood risk.

We follow: ASTM C836 and FEMA floodproofing standards for long-term protection and compliance.

Explore Our Local Review Highlights:

“I was very satisfied with their work to Waterproof our basement. They were on time, they were very diligent. I was so impressed with the quality of their work, that I also had them do outdoor maintenance that we had deferred for 20 years. They reinforced our deck, they installed a new cellar door and they matched the paint colors perfectly. We also had them repair and paint the front yard ironwork. We get comments on how beautiful and shiny our gates are!”

Storm Damage Prevention Tips for Long Island Homeowners

Protecting your home before the next storm is the smartest investment you can make. Use these proven storm damage prevention tips from Zavza Seal to keep your property safe, dry, and structurally sound year-round:

1. Seal and Waterproof Your Basement: Apply waterproof coatings, install interior drains, and maintain sump pumps to stop groundwater from entering during heavy rain or flooding.
2. Inspect and Clean Gutters Regularly: Clogged gutters and downspouts cause roof leaks and foundation pooling. Keep them clear to ensure proper runoff during storms.
3. Encapsulate Crawl Spaces: Seal crawl spaces with vapor barriers to block moisture, prevent mold, and stabilize humidity beneath your home.
4. Grade Soil Away from the Foundation: Ensure the soil slopes away from your home to prevent water from pooling near basement walls.
5. Install or Upgrade Sump Systems: High-capacity sump pumps with battery backups protect against power outages and rapid water intrusion during coastal storms.
6. Reinforce Foundation and Structural Walls: Address cracks early with structural-grade injection and bracing to prevent storm-driven soil pressure from worsening foundation damage.
7. Add Flood Barriers or Seawalls if You’re Near the Coast: Shoreline homes benefit from permanent barriers and seawalls that resist storm surge and saltwater corrosion.
8. Trim Trees and Secure Outdoor Items: High winds can turn loose branches and yard objects into projectiles that damage siding, roofs, or windows.
9. Install Backflow Prevention Valves: Prevent sewage backups into basements during intense rainfall and municipal drain overflow.
10. Schedule Regular Waterproofing Inspections: Annual checks by licensed waterproofing professionals help detect early signs of moisture intrusion and prevent major damage later.
