What Is Flood Mitigation?

Flood mitigation involves the management and control of flood water movement, such as redirect- ing flood run-off through the use of floodwalls and flood gates, rather than trying to prevent floods altogether. 

If your home is built in a flood prone area, flood mitigation can help prevent catastrophic damage in the event of a flooding event AND save you BIG on flood insurance! 

Flood Vent Installation

FEMA Compliant flood vents can significantly lower your insurance premiums and provide peace of mind. They dramatically reduce property damage when flooding strikes. Each structure is unique; we thoroughly review each flood plan to create your custom flood mitigation solution.  We consider many factors such as vent placement in relation to the flood path and in determining maximum hydrostatic pressure relief to best protect your home. Our team has extensive experience with a wide variety of flood vents; if you think your property may need them please reach out. Evaluations are always free!

Flood Proofing

Flood Proofing is defined by FEMA as:

 “Any combination of structural and non-structural additions, changes, or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents. The National Flood Insurance Program (NFIP) allows a new or substantially improved non-residential building in an A Zone (Zone A, AE, A1-30, AR, AO or AH) to have a lowest floor below the Base Flood Elevation (BFE), provided that the design and methods of construction have been certified by a registered professional engineer or architect as being dry floodproofed in accordance with established criteria. 

Floodproofing of areas below the BFE in residential buildings is not permitted under the NFIP exception communities that have been granted an exception to permit floodproofed basements. Floodproofing is not permitted in Coastal High Hazard Areas (Zone V, VE, or V1-30). It is recommended that floodproofing be implemented up to one foot above BFE for a factor of safety and to receive full credit for flood insurance rating. Limited enclosed areas below elevated within newly constructed and substantially improved residential and non-residential structures may be permitted provide that they are wet floodproofing. See Enclosure. Certain other categories of structures may be allowed to be wet floodproofed if a variance is issued and other requirements are met. See Agricultural Building and Accessory Building.”

Any questions? That’s what we are here for!

Basement Fills

Hydrostatic pressures can cause unbelievable damage to your property. Some of the most costly harm to homes in flood zones is to structures with basements and sub-grade crawl spaces. The upward pressures on the floor and the inward pressures on basement walls create a catastrophic situation in a flooding event. Take a look at the short video below to see this kind of damage.

The average flood damage claim on these types of structures is $125,000 while post-mitigated flood claims drop to $38,000.  It pays to mitigate and this is why insurance companies offer BIG reductions on flood premiums to homeowners who take on these projects. It’s not uncommon for flood insurance premiums to go from $7500 year to $1000 after converting from a basement to a crawl space.

Home Mechanix turns your basement into a crawlspace, significantly reducing the potential for damage and saving you money on your flood insurance! We have partnered professionals to assist with any mechanical relocations (water heater, oil tank, etc.) that may be necessary. We are with you during the whole process!


Crawlspaces in Virginia are exposed to the extremes of atmospheric conditions from very dry air in the winter to extremely humid in the peak of summer.  Encapsulations conditions the inside atmosphere of the crawlspace by isolating it from the ‘outside’ air and by removing the moisture from the air as it is being circulated.  This is a sure way to prevent the damage that is often found in the sub-structures of Virginia.  A properly installed dehumidifier in a sealed crawl space will maintain a healthy crawl by maintaining wood moisture and preventing damaging condensation underneath.  Home Mechanix has a thorough working knowledge and the experience to insure that your encapsulation is installed and maintained correctly.

Expert Consultation

If you need a specific expert for a job we will work with them so you don’t have to! We work with many partners to make ensure the job is done right. Here are some examples:


    Some mitigation jobs are complex and can get expensive.  Home Mechanix partnered insurance agents can generate an insurance analysis on your house to quote you for a post-mitigation rate before you spend the money on mitigating.  Not many insurance agents have a thorough working knowledge of FEMA flood code.  We know the ones in Hampton Roads that do.  If you are in need of answers that may require expert analysis on your property give us a call.


     Home Mechanix has insurance affiliates that have a thorough working knowledge of FEMA flood code. Not all flood insurance agents know FEMA flood policy, ours do.  FEMA flood code can be overwhelming to a homeowner,  our agents experienced in flood code will insure that your insurance premium is as low as FEMA flood code will allow.


     Handy with tools?  Don’t want to pay the labor and just need the technical know how?  We offer a flat fee service to assist the ‘do-it-yourselfers’ to insure that the installation is done right.  Home Mechanix will guide you through the installation process and the paperwork to insure that your mitigation project is done right.


     Our CFM partners are required by their certifications to remain current with FEMA flood policy.  CFMs are usually the first ones who know the changes to flood code that may affect locals and municipalities and could prove helpful with zoning issues and flood zone project.  They are trained to know how to read flood maps and know the requirements and standards of their state and local floodplain management programs.


    A certificate of elevation is required to properly mitigate a structure.  If the survey is done incorrectly it could cost you thousands extra.  For example, if the surveyor is unaware of the importance of the ‘LAG’ (lowest adjacent grade) is on a flood certificate it may require work than what is needed to mitigate.  Our surveyor affiliates are experience in flood and will get it right.
