Many homeowners are reluctant to invest in basement waterproofing measures for fear of the cost. If you have a basement waterproofing budget established, you can more readily protect your home from the effects of hydrostatic pressure.
Calculating Your Basement Waterproofing Budget
The cost of installing waterproofing measures inside and outside your home will vary from person to person. Each home is unique, making it a little difficult to pin down a precise budget for folks looking to protect their structural supports. On average, basement waterproofing endeavors can cost between $3,000 and $20,000, with costs including labor, excavation and different waterproofing measures.
Waterproofing Your Home’s Interior
When you do start thinking about waterproofing measures to invest in, begin with measures you can keep indoors. Some of the best interior waterproofing measures – and potential costs to consider – include:
- Interior drain installation – Interior drains work to collect any water that seeps inside your walls, floors, and wall-floor joint. This water is then directed to drain into a sump pump so it can be removed from the basement, thus keeping your belongings and the whole of your basement free of water. Depending on the size of your basement and how much of the pipe will need to be used, installation costs can range between $3,000 and $4,000.
- Sump pump installation – Sump pumps pump the water collected from your interior drainage system out of your basement and away from your home. Depending on the brand you invest in, installation can cost between $1,000 and $2,500.
- Vapor barriers – Vapor barriers are typically used for crawl space encapsulations to seal the below-ground area from the earth and the elements. But these durable barriers also can be used to help waterproof your basement walls. Installing these types of barriers can cost between $5,000 and $15,000, with each square foot of barrier adding to the installation price.
- Basement Dehumidifier – Excessive moisture and humidity are typical problems that plague basements in Columbia, SC, and the surrounding areas. To keep these issues in check, you’re going to want the help of a dehumidifier. We recommend an energy-efficient, self-draining unit that not only controls moisture and humidity, but also cleans and filters the air, and reduces odors and the potential for mold growth. Having this kind of protection installed in your basement can cost around $1,600.
- Additional repairs – It’s always possible that the hydrostatic pressure plaguing your home could have caused damage you didn’t notice on the first inspection of your home, such as foundation cracks.. You’ll want to repair these damages before they can evolve into something more significant. The cost of repairs will vary, but you should have between $500 and $1,200 put away just in case.
Waterproofing Your Home’s Exterior
The outside of your home is just as susceptible to damage as the inside of your home. As such, you’ll want to take the necessary steps to waterproof your home’s exterior while protecting the interior. The measures that can help you do so include but are not limited to:
- Downspouts – You can pair downspouts with your gutters to direct runoff away from your home. Installation can run between $750 and $1,550.
- Exterior drains – Like interior drains, exterior drains require a system of pipes around the perimeter of your home to drive water out of your basement. Installing an exterior drain can run you between $4,000 and $6,000, with costs varying based on the size of your home and the length of pipes needed to move water away from sensitive housing materials.
- Excavation – Note that none of the above-suggested costs include the price of excavating your home. Most of the time, a contractor will need to dig your foundation and basement out to apply exterior waterproofing measures, unless you’ve thought ahead and are having said measures installed at the same time your home’s being built. The cost of excavation will vary based on the size of your home and the depth at which your basement was established. That said, you can expect prices to start at $10,000.
- Exterior repairs – There’s always a chance that contractors may have to repair damage done to your home by hydrostatic pressure that went undetected. You’ll want to have between $2,500 and $3,500 put away to deal with these costs, just in case.
Paying for Labor
Note that none of the aforementioned costs include labor. Installing waterproofing measures inside and outside your home can cost you between $1,500 and $3,500. Again, those costs will vary based on the unique features that set your home apart from the rest.
