When it comes to protecting your home’s foundation, especially in colder climates, one of the most important factors to consider is how your foundation handles freeze and thaw cycles. These cycles, which occur when temperatures drop below freezing and then rise again, can cause significant damage to your home’s foundation over time. Fortunately, using the best exterior foundation sealer can help protect your foundation from the harsh effects of these cycles, preventing costly repairs and extending the life of your home’s structure.
