A wet basement can be a major headache, and understanding basement waterproofing cost can feel overwhelming. If you’re dealing with a damp or wet basement, it’s important to know the average costs and what factors impact those prices.
This article breaks down the most common waterproofing methods, along with their costs and the elements that influence your investment. With this information, you’ll be able to plan and budget more effectively for keeping your basement dry.
The Average Basement Waterproofing Cost
The basement waterproofing cost can vary significantly depending on the scope of the work. A simple fix for a minor leak will cost much less than comprehensive exterior waterproofing.
On average, basement waterproofing costs range from $2,300 to $7,575, with the typical price being around $4,920.
Having a general idea of these price ranges can help you plan your budget and choose the best solution for your needs.
Factors Influencing The Cost of Basement Waterproofing
Basement waterproofing cost isn’t one-size-fits-all. Several factors can influence the price.
Basement Size
A larger basement means higher costs for materials and labor. More square footage equals more materials, especially with exterior waterproofing, where excavation costs are tied to the area around the foundation walls.
A smaller basement will have a lower cost compared to a larger one. The total cost is heavily influenced by your basement’s square footage.
Water Source and Severity
Minor seasonal dampness and constant water intrusion will require different solutions impacting cost.
High water intrusion often requires exterior methods like a French drain or foundation waterproofing, which can be more expensive than other solutions. Costs will vary depending on the required work.
Foundation Condition
Crumbling foundation walls require repairs before waterproofing can start. Remember, any necessary foundation repair would increase the basement waterproofing cost and may add to the final cost of the job.
A larger basement might require additional structural repairs. Interior basements, especially older ones, can have costly foundation issues and structural damage.
Additional Factors That Affect Costs
Keep an eye out for added project costs beneath the main waterproofing job. Some extra factors may end up impacting your total cost and can greatly influence the final price tag of basement waterproofing services.
Mold Remediation
Mold often accompanies basement water issues. Professional mold remediation costs range between $500 and $3,500, significantly adding to your waterproofing costs. It’s a crucial step to protect your family’s health.
The extent of the mold and methods used for remediation will significantly affect these costs. Mold remediation costs increase depending on the size of your basement and severity of mold damage.
Permits
Major waterproofing jobs requiring exterior excavation often need permits – check local regulations. Costs depend on your area’s laws, which influence any basement waterproofing project.
Ensure your contractor factors permitting fees into the total cost. Your contractors should handle acquiring necessary permits and including those costs in the overall basement waterproofing cost.
Landscaping
Sometimes, adjusting your landscape is part of waterproofing. This can involve improving drainage by adding gutters and extending downspouts or grading to direct surface runoff away.
Landscaping and drainage costs rise in proportion to the extent of exterior waterproofing and depend on any exterior basement waterproofing involved.
6 Common Methods of Basement Waterproofing with Costs
Several methods work for basement waterproofing — some simple, some elaborate. If you have noticed water penetrating basement walls, any of these waterproofing methods could be a solution for you.
1. Interior Waterproofing
This method deals with water after it enters by channeling it toward a sump pump system. Expect to pay between $500 and $3,000.
Consider this option for managing water that has already entered your basement.
2. Exterior Waterproofing
Exterior waterproofing keeps water from penetrating the foundation from the outside. Because this involves digging up to the basement foundation, costs range from $1,000 to $15,000.
This effective method for foundation waterproofing and dealing with wet basements prevents water intrusion before it becomes a basement issue.
3. Crack Injection
This method seals foundation cracks with epoxy or polyurethane. Costs range between $200 and $800 per crack. More complex foundation cracks might cost as much as $7,000 to repair.
If water is collecting in your basement or penetrating your basement walls due to foundation cracks, crack injection may suffice.
4. Interior Drain Systems (French Drains)
An interior drain system diverts infiltrating water toward the sump pump. While effective at capturing most incoming water intrusion, a French drain can be one of the priciest methods.
Expect to pay between $4,000 and $17,000 for this basement sealing method, involving substantial labor for installation.
5. Sump Pump Installation
The sump pump diverts any water in the drain system up and outside. Sump pumps can protect your home from water damage and flooding, and reduce remediation costs if you’ve experienced flooding in the past.
Costs range from $600 to $2,500. It’s the core of interior waterproofing. Ensure your basement waterproofing project includes one.
6. Waterproofing Coatings
These coatings offer a decent waterproof barrier on interior or exterior basement walls. Consider this for stopping minor water issues or preventing moisture.
They run from $3 to $12 per square foot with professional installation adding to that overall waterproofing cost. A foundation coating can also provide additional protection.
