How Much Does Basement Waterproofing Cost?
Basement waterproofing may be necessary if you have a basement rather than a crawl space or slab since most water is naturally going to flow around the house and down into the ground. This increases the chance that your basement can flood, become damp, or even have that “basement smell.” If something was to happen to your home’s foundation, it could mean a disaster to your basement. The cost of waterproofing is going to greatly vary on your house size, what type of waterproofing you want done, and other various factors.
How much is it?
- Gutters are one of the top choices when waterproofing a home. These gutters will collect the water from the rooftop and push the water away from the foundation. Rain gutters will greatly vary depending on the size and quantity. Expect to pay $15 to $75 for rain gutters that vary from a few feet to as long as 20 feet or more. Having them professionally installed will add to the price tag as well.
- For a damp basement, it may be ideal to purchase a dehumidifier. This is going to draw out the moist/humid air and push cooler air back into the room. This is a great way to get rid of the smell. A dehumidifier can cost $100 to as much as $1,500 for a larger basement.
- There are do-it-yourself kits that allow a drain to run along the inside of the basement walls. These drains will then run the water straight to the sump pump in the basement. This will cost around $9 to $13 per foot if you want to do it yourself. Professional installation will add around two to three times the cost.
- Sealing cracks in the basement walls will require a rubberized compound. This compound is going to waterproof the wall from allowing water into the basement itself. After the compound is applied, a special water proof paint will be required in order to expand the seal. A gallon of this paint can cost $20 to $30, while the caulk can cost $7 to $20 for a tube.
- There are professional waterproofing companies that can analyze your situation. They will recommend what needs to be done, but this is going to greatly vary depending on the extent of your problem. Estimates can range from $500 to as much as $15,000 or more for a more serious problem.
What are the extra costs?
- A professional waterproofing company and/or contractor is going to charge based on the job. This can range from $500 to as much as $15,000 or more depending on the complexity of the job itself.
- If you choose to purchase a dehumidifier, you will need to purchase new filters every so often as well.
What is going to be included?
- Depending on the solution that you choose, the materials will be included as well as instructions on how to use them.
- Choosing a dehumidifier will include a warranty as well as other accessories to ensure that it works properly for your basement.
How can I save money?
- Consider all options as they are all going to do different things for your basement. The cheapest route, such as caulking, may be the best way to go. If you are unsure of which way to go, highly consider hiring a home inspector to see what he recommends.
- If you are going to hire a professional laborer, use services such as Service Magic to find the best quote in your area.
