The Real Seal Basement Waterproofing & Foundation Repair offers crawl space encapsulation in Chicago, IL, to help battle moisture, mold, and a musty breathing area. The air you breathe comes from the floor below you, and if your crawl space is allowing humid air to enter your home, you are going to notice it.
Does Your Crawl Space Have These Problems?
-
Leaks
- Leaks are the beginning stage of your crawl space showing signs of damage. Once water enters, more serious problems start to develop. -
Humidity
- Once moisture and water start to pool up in your crawl space, it starts to become humid, developing mold and musty smells. -
Mold
- Mold can create allergens and toxic breathing space. Most homeowners don’t realize that a certain amount of air from the crawl space makes its way up and into their home’s living area. A cleaner crawl space equals cleaner air. -
Drywall Cracks
- When you have cracks in your drywall, it may be an indication that you have sagging I-beams, usually due to foundation settlement. -
Uneven Floors
- Uneven, sagging floors are either a result of a failing foundation or failing crawl space.
Review From One Of Our Customers
“Reasonably priced. I compared their services with US Waterproofing and Perma Seal. Real Seal really beats them on customer service and definitely in price. Manny gave us the best price for the amount of work we wanted done and was very personable. We had the vapor barrier installed with an interior drain tile system, encapsulated our crawl space and installed a new primary sump pump. They saved us about $10,000 in cost compared to their competitors for doing exactly the same amount of work. I had an excellent experience with them and would definitely recommend their services. I have received compliments from other contractors and family on what an amazing job they did.“

Our Crawl Space Encapsulation Services in Chicago, IL
Our crawl space services are targeted to address various crawl space problems, including high humidity levels, water pooling, mold, and musty smell. The services include the following encapsulation solutions:
Crawl Space Encapsulation
Crawl space encapsulation is a sealing technique that involves lining the walls and floors with overlapping sheets of thick polyethylene plastic, keeping moisture out. The air you breathe comes from the floor beneath you, so you want an effective barrier to ensure clean air.
I-Beam Supports
I-Beams are placed at the junctions of your home’s existing I-beam sections. They include footings that help the support’s weight to be distributed over a larger area of soil. This prevents settlement of the support and subsequent floor sagging.
Crawl Space Waterproofing
Our crawl space waterproofing solutions offer protection from water intrusion, keeping your crawl space dry throughout the year. We implement tailored solutions to keep water out and safeguard the space from the risks of flooding and water damage. We also offer crawl space to basement conversion services, along with waterproofing.
Crawl Space Drain Tile
The crawl space drain tile system works the same as a basement drain tile system, except instead of being placed under your foundation floor, it’s placed underneath your crawl space. A perforated pipe is laid in a bed of washed stone, and as water gathers around and under your home’s foundation, this pipe gathers the water and redirects it to a sump pit. From here, the sump pump will eject the water from the basement.
Crawl Space Sump Pump
The same thing applies to the sump pump for a crawl space as it does for a basement. The drain tile pipes lead to the sump pit, and when the sump pit is full, the sump pump ejects the water away from the foundation.

Implementing Our Crawl Space Encapsulation System
We personalize our crawl space encapsulation solutions based on your home’s needs and requirements. Here’s how our process works:

Step 1: Seal Crawl Space Vent Caps
We will seal your crawl space vents and ensure proper insulation, preventing moisture and air from coming in during the encapsulation process.

Step 2: Prepare Insulated Liner
Our team will prepare an insulated liner with an R-9 insulation value to improve the energy efficiency of your home. It will also help keep your heating and cooling costs down.

Step 3: Cut the Drain Board and Underlay in the Shape of the Crawl Space Floor
Our team will measure your crawl space size and cut the drain board and underlay to custom-fit the area, including the pipes and shape of your crawl space

Step 4: Install Wall Liner and Lay Drain Board
We will install a high-quality crawl space wall liner along with a drain board, which will help us prepare the space for encapsulation and keep it encapsulated.

Step 5: Drain Board Underlay for Floor Encapsulation
Once the drain board underlay is installed, you will get a stable surface to walk upon and store your belongings in. It will also protect your crawl space floor from punctures from rocks and debris.

Step 6: Secure Liner with Waterproof Seam Tape
We will install a liner and secure it with 4-inch waterproof seam tape. As a result, your crawl space will get added safety from moisture issues. (Image 6)

Step 7: Dehumidifier Installation
For enhanced mold prevention and moisture control, we will install a dehumidifier in your crawl space. A dehumidifier will help keep the humidity levels down in your crawl space and ensure a comfortable environment.

Step 8: Happy Employees Make Happy Customers
Our friendly and helpful team stays fully committed to the project and keeps your home’s needs and requirements in mind throughout the process. As a result, we are able to pull off a job that results in happy and satisfied customers.

Step 1: Schedule An Inspection
Once you schedule an inspection, we will visit your property to evaluate the condition of your crawl space. We check thoroughly to identify problems like moisture damage, water intrusion, cracks, and structural issues. This evaluation helps us determine problems in your crawl space accurately and plan a suitable encapsulation solution.
Step 2: Receive A Personalized Estimate
After our inspection, we prepare a detailed estimate depending on the specific needs of your crawl space. We provide you with an overview of the project costs, process, and timeframe.
