While fabulous for flowers, trees and lawns, all this rain is often not so good for basements! Underground streams, rising water tables and inland wetlands plague our area and can have disastrous consequences when we get the type of deluges we’ve been having lately.
Being subterranean means basements are at particular risk for flooding during heavy storms and with winter snow melt. Ground water can penetrate walls and cracks causing thousands of dollars’ worth of damage. If you head downstairs after a rain and see water pooling in your basement, it’s time to consult a professional.
What’s involved in remediating a flooded basement?
1. Safety first: Before entering a flooded basement, ensure it's safe to do so. Turn off the electricity and gas supply to the affected area to avoid electrical hazards. Wear protective gear like rubber boots and gloves to minimize contact with contaminated water.
2. Remove standing water: Use a sump pump, wet vacuum, or a professional water removal service to extract standing water from the basement. Ensure the area is thoroughly dried to prevent mold growth and further damage.
3. Dispose of contaminated materials: Remove and dispose of any water-damaged or contaminated materials, such as insulation, drywall, carpet, and furniture. These items can harbor mold and pose health risks if not properly discarded.
4. Clean and disinfect: Clean all surfaces that came into contact with floodwater using a disinfectant solution to prevent mold and bacteria growth. Pay special attention to walls, floors, and any items that can be salvaged.
5. Dry and dehumidify: Use fans, dehumidifiers, and open windows to promote airflow and accelerate the drying process. Monitor humidity levels to ensure they return to normal to prevent mold growth. It may take several days to fully dry out the basement.
How can I stop my basement from flooding next time?
1. Improve exterior drainage: Ensure your home's exterior is properly graded to direct rainwater away from the foundation. Install downspout extensions to carry water at least 6 feet away from the house to prevent it from seeping into the basement.
2. Install a sump pump: Consider installing a sump pump in your basement. This device can efficiently remove excess water by collecting it in a sump pit and pumping it away from the foundation. Make sure to maintain and test the sump pump regularly and most importantly, get one with a battery back-up! This way, if the power goes out, the pump will continue to work!
3. Seal basement walls and floors: Waterproofing your basement walls and floors can help prevent water infiltration. Apply waterproof sealant or coatings to basement walls, and consider adding a waterproof membrane or epoxy flooring to create a barrier against moisture.
4. Check and maintain gutters and downspouts: Keep your gutters and downspouts clean and free of debris to ensure proper rainwater drainage from your roof. Regularly inspect for leaks and ensure they are securely attached to your home to prevent overflow near the foundation.
5. Install window well covers: If your basement has window wells, consider installing covers to prevent rainwater from pooling around basement windows. This can be particularly helpful in preventing water intrusion during heavy rains.
Additionally, you may want to consult with a professional waterproofing contractor who can recommend customized solutions to address your basement flooding concerns effectively.
Keep in mind that severe flooding may require professional assistance for proper remediation and mold prevention. Consult with a water damage restoration specialist to assess the extent of the damage and to receive guidance on the best remediation steps for your specific situation.
