We Are The #1 Flood Damage Cleanup Company On Long Island For 40 years!

When Quality is What You Want, Put your Trust in Us

Dealing with flood or water damage in your home or property isn’t easy. While it can cause a number of financial headaches, it can also be a danger to you and those around you.

Once moisture is introduced to an environment in large quantities it gives bacteria and microorganisms the opportunity to grow at unhealthy levels. In turn, those levels can open your property to several other unsavory and potentially harmful situations like mold, degradation, and microbial growth.

However, the sooner you get the flood damage taken care of, the less likely these situations are to occur, and that's when we come in. We want to help get you back on your feet.

You can trust our licensed and skilled emergency water restoration and flood clean up team to put your needs first and to do a superior job every time.

It is our job to make sure you’re satisfied with your flood removal and water restoration experience. We go the extra mile to make sure you understand each step of the flood clean up process and consult with you on any concerns or changes that need to be made.

Water Damage Inspection

Detailed Food Repair Estimates
Once we have an approved scope of work we will immediately write an estimate for the water damage cleanup.

Sanitization
Once the water is extracted and the carpet, padding, and any wet drywall has been removed, the contents will be put on blocks and an anti-microbial to protect against any bacterial growth will be applied.

Drying / Dehumidification of Flooded Space
We will set up high powered fans made for drying water damaged areas. We will also set up dehumidifiers to remove any moisture in the materials as well as the air. This step takes 72 hours to complete to ensure all moisture is taken care of properly.

Property Reconstruction
Our skilled team of contractors will repair your property to your specifications so you can move on with your life.

Direct Insurance Billing
If the loss is covered by your homeowners insurance policy Flag will bill your insurance company directly and wait for payment from them.
