All of these projects will help protect your home and belongings from flood damage. Some of them also could lower your flood insurance costs. These cost-saving actions include elevating your home, mechanical equipment, and major appliances. Filling in your basement or crawl space also could lower the cost. Most of these jobs will require professional assistance from an electrician, plumber, or engineer.
The cost of these projects can range from $1,000 to tens of thousands of dollars — even $100,000 or more to elevate your home. For that reason, you should get an independent opinion from a drainage specialist or a home inspector with expertise in drainage issues. They can help you determine whether these steps would be helpful and if they are worth the cost.
Do not seek your initial advice from contractors. They will have a financial incentive to tell you the project is necessary so you will pay them to do the work.
