When your basement starts leaking, the last thing you want is mold to grow or uninvited pests to show up in the dead of night. Both scenarios are possible if you don’t waterproof your basement. Waterproofing can help you stop leakage and all undesirable effects that come with it, including pests and mold. But how much does it cost to waterproof a basement?
Well, that depends on whether you want to waterproof the interior of the basement or the exterior or both. The cost will go up if you waterproof both sections. Here’s how much you can expect to incur in terms of waterproof basement costs in Denver, CO.
In case you want to waterproof the exterior of the basement, talk to your local basement waterproofing contractor. They will provide a quote based on the size of your basement, which could be anywhere between $3 and $9 per square foot. Small repairs and filling cracks will likely cost $400 to $1,500. Enhancing the draining could be anywhere between $2,000 and $6,000. Note that these are ranges, not the exact prices. The final cost, in most cases, could be higher depending on the condition of the basement.
If there’s external leaks or damages, you will have to do an excavation to get to the area that needs to be repaired. This will cost you anything from $100 to $250 per linear foot. Installing drains and window wells costs $500 to $2,000.
Water damage repair after flooding will likely cost you $200, the bulk of which goes toward standing water removal. For extra protection, it’s advisable to waterproof the foundation. This isn’t cheap. It could cost $5,000 to $10,000.
Just like interior basement waterproofing, your contractor could charge you per linear foot or set a fixed project fee. Take time to compare rates and request a quote when you’re ready. You could save hundreds of dollars by working with a contractor who uses cost-effective waterproofing solutions and products.
Waterproofing from the interior can double the protection of your basement. On average, you will spend anywhere between $3,000 for up to 1,000 sq. ft of basement. Waterproofing sealant will cost you $10-200 per bucket. If you have a crack in the foundation, you will have to seal it with epoxy injections, which costs $300 to $500 per crack repair.
Waterproof paint will cost anywhere between $30-200. But it's not necessary. To keep floodwater out of your home, you may have to install a pump that goes for $500-$1,000 per unit. If floor drains are required, you will spend at least $200 (on the lower side) up to a maximum of $10k.
Basement waterproofing projects usually require local permits. You will also have to hire a home inspector and/or pay building fees. Besides this, there are the general contractor fees (which could be hourly or fixed), materials and supplies. So factor all these when drawing up your budget.
When waterproofing your home, your contractor may advise you to make some enhancements or carry out some necessary repairs. You can call these improvements or enhancement costs. Sometimes, you may have to remove your HVAC unit, which can take up to two hours. For this, set aside at least $300. Deck or patio removal may cost you $400 to $600, and it’s another intensive activity that could take three hours. To remove an existing fence and haul, you will spend at least $500. Removing unreinforced concrete from your driveway will set you back $2,000. Note, these are just estimates and not the ultimate cost.
Across Denver, the average cost of waterproofing is $3.50 to $6 per square foot. This could go up to $9 per square foot if your contractor is going to use thorough waterproofing methods. Pricing varies from one place to another depending on the extent of leaks and whether excavation and extras such as sump pumps are required.
Regardless of whether you do exterior or interior basement waterproofing, your local contractor will provide you with a transferable warranty that could last for 10-25 years. Good warranties often come with little or no additional cost.
Waterproofing your basement and repairing cracks in your foundation and crawl space can prevent water from entering your home. The outcome is a clean, mold-free, pest-free and hospitable home with fresh indoor air and ambient conditions. Typical waterproofing projects can take anywhere from a couple of days to a few weeks depending on the size of the basement and the underlying issues.
