Sharing is caring!

If you are building or buying your dream home, it’s important to hire the right contractor who knows how to seal a house foundation properly and effectively. Sealing your foundation protects against insects, rodents, and water that can cause mold in your home. Foundation leaks can be devastating to your home, and they’re expensive to fix. Instead of waiting until this happens, you can take steps now to seal and protect your foundation. Here are some tips and tricks on how to seal and waterproof a foundation.

Do I Need To Seal My Foundation?

Sealing your foundation is often an essential step in stopping water from penetrating underneath. This will prevent moisture from getting into any cracks or openings in your walls, woodwork, and even foundation. While it may be tempting to skip over sealing your foundation if you live in a warm climate, it’s not worth taking that risk! It’s always better to be safe than sorry.

In most cases, it’s recommended that you seal a house foundation. Doing so will not only save you money on expensive repairs in case water damage does occur, but also prevents mold from forming and holding spores that are harmful to your health.

In some cases, however, your home may not need to be sealed. You should consider sealing your foundation if you’ve experienced water leaks in or around your foundation or have noticed cracks or holes on your exterior walls. If you’re not sure whether you need to seal your foundation, consult with a professional. They can perform an inspection and tell you if it’s necessary for sealing and waterproofing.

What to Use

When it comes to sealing your foundation it's important to use the right products. There are two main types of sealants for concrete and masonry, water-based and solvent-based. Water-based sealers generally offer better adhesion with less shrinkage or peeling issues, making them ideal for interior applications like unsealed foundations that come in contact with water in basements or bathrooms.

Solvent-based sealers are better for exterior applications like a house foundation or garage floors, as they are formulated with products that protect against moisture and stand up to harsher environmental conditions. They should be applied using a brush, roller or sprayer. Solvent-based sealers can also be tinted to achieve specific colors for your application. It's important to note that these types of sealants need two weeks of cure time before being exposed to traffic.

Waterproofing Exterior Foundation

Foundation waterproofing is one of those DIY tasks that everyone has on their house-improvement list, but few people ever tackle. After all, taking care of your foundation can be kind of complicated, and if you’re not careful, or if you choose an unqualified contractor, you can end up with leaks or soggy walls instead of dry basements. 

Whether you hire someone or decide to tackle it yourself, foundation waterproofing is generally easier and less expensive than you might think. According to Home Advisor foundation sealing can cost between $2,257 and $7,279.

Some of that cost depends on your home’s foundation type, and how extensive you want to make your waterproofing efforts. Crawl spaces are particularly difficult because they usually require multiple layers.

How to Waterproof Your Foundation

With a few tools and materials, you can seal up your foundation so water runs away from your house rather than through it. With time, energy and knowledge, you can seal your foundation for a very reasonable price. 

Whether you're looking to do it yourself or have a professional do it for you, the steps are essentially the same. The most important aspect of sealing your foundation is that you choose materials and methods that are going to be appropriate for your situation and effective at creating an impermeable seal. Different foundation types and situations call for different solutions.

The first step when it comes to sealing a foundation is determining what type of structure you're dealing with. Once that's done the next step is to determine the right sealant and begin applying it. Your method will depend on where water has infiltrated in your foundation, so you'll need to assess its source (e.g., cracks or water seepage under doorways) before choosing your methods and materials.

Sealing the Gap Around the Foundation of a House

With any home, you’ll have gaps at your foundation. These gaps are where moisture and pests can enter, but they can also cause cracks in your walls and floors. You can seal these entry points with mortar or caulk, but most people only get around to it when their basements or crawl spaces start flooding. The best way to prevent future problems is sealing them while everything else is new—after all, what better time than now? 

The idea of sealing your foundation may not sound all that exciting, but it’s an important step in protecting your home. There are several benefits of sealing your foundation including reducing moisture issues and acting as insulation against heat loss. On top of these savings on heating and cooling bills, there are also health concerns that come with having moist conditions around your house.

Leaving your Foundation Unsealed

Sealing your house foundation is one of those home improvement jobs that you’ll often be advised not to skip. While sealing a foundation may sound like an unnecessary extra step, there are some circumstances where it can prevent serious damage from occurring in your home. If your foundation has been left unsealed for any length of time and moisture has begun to infiltrate it, things could get nasty pretty quickly, especially during cold winter months when water condenses inside walls. To help you avoid future problems with dampness or mold, seal up those cracks!

You may think that your foundation is already sealed, but chances are there’s still a gap or two around your home where water can sneak inside. If you’re moving into an older house or you have reason to believe your foundation is unsealed, it’s always worth double-checking for gaps before winter comes around. Sometimes these things aren’t obvious so it's important to bring in the experts who know what to look for. An inspection could save you both time and money down the road.
