Foundation Sealant: Dos & Don’ts
A well-sealed foundation is crucial for the structural integrity and longevity of your home. Applying foundation sealant can protect your home from water damage, moisture infiltration, and other issues that can compromise your foundation.
But remember: sealing your foundation on your own comes with a few hazards.
This guide will walk you through the dos and don’ts of sealing your concrete foundation, helping you make informed decisions to maintain a strong and durable structure.
Dos for Applying Foundation Sealant
- Do consult a professional before applying any kind of sealant. Applying a sealant on your own runs the risk of exacerbating foundation issues. If you seal it while hydrostatic pressure is actively cracking your foundation or the soil is settling, a sealant will only give that pressure the perfect surface to push against. Sealing under these circumstances may compromise your foundation further. A foundation expert can give you a free inspection and provide a personalized plan to stop your foundation cracking.
- Do use a sealant with a comprehensive waterproofing solution for maximum protection. Foundation sealant can make your problems worse if you don’t address the root cause of cracks and moisture infiltration. A comprehensive waterproofing solution includes structural solutions like wall anchors and drainage systems like sump pumps. If you just use sealer, the foundation cracks will only get worse.
- Do select a long-lasting foundation sealant that resists abrasion, chemical damage, and UV light. Your foundation sealant should be durable and long-lasting, able to withstand wear and tear from the elements. Look for a sealant that resists abrasion, chemical attack, and UV light to ensure that your foundation remains protected for years to come.
- Do invest in high-quality sealants from reputable manufacturers. Not all foundation sealants are created equal. To ensure that you are using the best possible product, choose a sealant from a reputable manufacturer with a proven track record of delivering high-quality, effective products.
Don’ts for Applying Foundation Sealant
- Don’t let moisture or contaminants enter the concrete while it is drying. When your foundation is drying, it is essential to keep it free from moisture and other contaminants. These substances can weaken the concrete and reduce the effectiveness of the sealant.
- Don’t ignore any cracks or gaps in the foundation before applying the sealant. Before applying any foundation sealant, inspect your foundation for cracks, gaps, or other imperfections. Address these issues by filling them with a suitable patching compound to ensure that the sealant can work effectively.
- Don’t neglect to inspect your foundation regularly. Regularly inspect your foundation for signs of wear. While high-quality sealants are designed to last for years, they can still degrade over time, so it’s essential to monitor your foundation’s condition.
- Don’t compromise on quality materials when sealing your foundation. Investing in high-quality materials for sealing your foundation is essential for its long-term stability and protection. Cutting corners on the quality of the sealant can lead to more significant problems down the line, so prioritize the best materials for your foundation.

Foundation Sealant FAQs
The frequency of reapplying foundation sealant depends on several factors, including the type of sealant used, the climate, and the exposure of your foundation to harsh elements. Generally, high-quality sealants can last between 5 and 10 years. However, it’s essential to inspect your foundation regularly to identify any signs of wear or damage that may indicate the need for reapplication. If you notice issues or are uncertain about the condition of your sealant, consult a professional to determine the best course of action.
Applying foundation sealant offers numerous benefits, including:
- Enhanced protection from water damage: A well-sealed foundation is less susceptible to water infiltration, helping prevent damage from basement leaks, flooding, or groundwater.
- Increased durability: Foundation sealant reinforces the concrete, making it more resistant to wear and tear from the elements.
- Reduced risk of mold and mildew: By preventing moisture infiltration, foundation sealant helps reduce the likelihood of mold and mildew growth in your home.
- Improved energy efficiency: A sealed foundation can reduce drafts and improve insulation, leading to lower energy consumption and costs by fending off the stack effect.
The primary risks associated with applying foundation sealant arise from issues like:
- Improper application
- Using low-quality materials
- Using sealant without addressing the root causes of cracks.
Inadequate sealing can lead to moisture infiltration, causing water damage, mold growth, and other issues. Additionally, low-quality sealants may not provide the necessary protection and durability, resulting in the need for more frequent reapplication. To mitigate these risks, it’s essential to follow best practices when sealing your foundation and invest in high-quality sealants from reputable manufacturers. Always consult a professional basement and foundation waterproofing specialist before using concrete foundation sealer.
