As a homeowner, keeping your basement dry and free from water damage is crucial. One of the best ways to do this is by installing a basement waterproofing system. With the wide variety of waterproofing options available, it can be challenging to choose the best one for your home.

Here are five common mistakes to avoid when choosing a basement waterproofing system.

Mistake #1: Not Addressing the Root Cause of Water Intrusion

Before selecting a basement waterproofing system, it’s essential to understand why water is entering your basement in the first place. Ignoring the root cause of water intrusion can lead to continued water damage and even the failure of your waterproofing system. Common causes of water intrusion include poor drainage, cracks in the foundation walls or floor, and high levels of humidity. Identifying and addressing these issues before installing a waterproofing system is crucial for a long-lasting solution.

Poor drainage is one of the leading causes of water intrusion in basements. Water can enter your basement if the surrounding soil is not graded properly or if the gutters and downspouts are not directing water away from your foundation. Water can also seep into your basement if the soil around your foundation is too saturated. To address poor drainage, you may need to install a French drain, which involves digging a trench around the perimeter of your basement and installing a drainage pipe. This will direct water away from your foundation and prevent it from entering your basement.

Cracks in your foundation walls or floor can also allow water to seep into your basement. These cracks can be caused by a variety of factors, including settling of the foundation, temperature fluctuations, or poor construction. To address these issues, you may need to have the cracks sealed or repaired. This will prevent water from entering your basement through these openings.

High levels of humidity can also lead to water intrusion in your basement. This can be caused by poor ventilation, inadequate insulation, or even the use of humidifiers in your home. To address high levels of humidity, you may need to install a dehumidifier in your basement. This will remove excess moisture from the air, reducing the risk of water damage.

Mistake #2: Choosing the Wrong Waterproofing System for Your Home

Not all basement waterproofing systems are created equal. Choosing the wrong system for your home can lead to ineffective protection against water damage. The two main types of basement waterproofing systems are interior and exterior.

Interior systems include French drains, sump pumps, and dehumidifiers. A French drain is a trench filled with gravel that directs water to a sump pump, which pumps the water out of your basement. A dehumidifier removes excess moisture from the air, reducing the risk of water damage.

Exterior systems involve excavating the soil around the foundation to install a waterproof membrane. This membrane creates a barrier between the soil and the foundation, preventing water from entering your basement. Depending on the severity of the water intrusion and the location of the problem, one system may be more effective than the other. It’s essential to consult with a professional to determine which system is best for your home.

Mistake #3: Focusing Solely on Price

While price is undoubtedly an important consideration when selecting a basement waterproofing system, it should not be the only factor you consider. Choosing the cheapest option may result in subpar materials or installation, leading to a less effective waterproofing system. On the other hand, the most expensive option may not be necessary for your specific needs. It’s crucial to find a balance between cost and effectiveness when selecting a waterproofing system.

When considering cost, it’s important to factor in long-term savings. While a more expensive system may require a larger upfront investment, it may be more cost-effective in the long run due to its durability and effectiveness. In contrast, a cheaper system may require frequent repairs or replacements, leading to higher costs over time.

Mistake #4: Not Considering the Impact on Home Value

Installing a basement waterproofing system can have a significant impact on your home’s value. A properly installed and effective waterproofing system can increase your home value by preventing water damage and creating a more functional and livable space. There are many benefits of finishing your basement as well, so it goes hand-in hand to put a waterproofing system in place at the same time. On the other hand, a poorly installed or ineffective system can decrease your home’s value and make it more challenging to sell.

When selecting a waterproofing system, it’s important to consider the impact on your home’s value. Choose a system that is effective and durable while also being aesthetically pleasing and adding value to your home.

Mistake #5: DIY Installation

Installing a basement waterproofing system may seem like a simple task, but it’s crucial to hire a professional. DIY installation can lead to ineffective waterproofing and even cause further damage to your home.

Choosing the right basement waterproofing system is essential for protecting your home from water damage and maintaining its value. By avoiding these common mistakes, you can ensure that you select a system that is effective, durable, and tailored to your home’s specific needs. Remember to address the root cause of water intrusion, choose the right system for your home, balance cost and effectiveness, consider the impact on home value, and hire a professional contractor for installation. With the right system in place, you can enjoy a dry, functional, and valuable basement for years to come.
