In this Costimate we will focus on the cost of sealing your interior basement walls before you have issues with water. We\u2019ll explain the different basement waterproofing techniques, as well as provide you with the cost of the different sealant products available on the market. At the bottom of the page, you\u2019ll find a section that lets you compare basement water sealing costs from other leading websites, as well as review what homeowners around the country have paid for their project. Once you have a better understanding of how much it will cost to seal your basement, you\u2019ll be able to decide if this is a do-it-yourself project or if you need to hire a professional to do the work.<\/p>\n Waterproofing and Sealer Price Factors<\/strong><\/span><\/p>\n Many factors will affect the right basement sealant for your specific needs. Before running down to Home Depot or Lowes for supplies, it\u2019s important to make sure that you understand\u00a0which basement sealing product and\u00a0solution is right for you. Sealing concrete basement walls\u00a0that are\u00a0not yet leaking or causing problems is going to be the most affordable solution and can usually be done by one person in a weekend. If your basement is leaking or you have an already finished basement, the cost of sealing your basement may dramatically increase if you want to get the job done right. Step one in determining your basement waterproofing cost will depend on which of the following options fits your situation:<\/p>\n Regardless of the current situation, you can expect to spend the following retail prices\u00a0on your basement sealant, depending on which type of walls you have:<\/p>\n Cost of Supplies<\/strong><\/p>\n Once you\u2019ve determined how you will seal your interior basement walls, you will want to factor in the following supplies to your overall basement sealing cost:<\/p>\n As we mentioned above, the most important part of this project is inspecting your basement for water and moisture. Many local companies will provide a free inspection of your basement for mold and moisture in the walls. If your basement shows no signs of moisture then an inspection should\u00a0not be necessary.\u00a0Permits are not required for a simple sealing of interior basement walls and floors.<\/p>\n Installation Labor Costs<\/strong> As with any project, there are a number of factors that will determine how much a handyman will charge you and how long it will take. Some projects may be quoted on a \u201cper-project\u201d basis, rather than hourly, depending upon who you work with.<\/p>\n A few things that will affect your overall costs:<\/p>\n Completed Installation Time<\/strong><\/p>\n The time it takes to waterproof your interior basement walls with sealant will vary depending on the size of the basement and number of walls. The following guide can give you a rough estimate of how long you need to set aside.<\/p>\n The total labor hours described above include brushing on the first coat of sealant and then using a roller to apply the second coat. The times do not include the typical 4-hour time frame for drying in between coats. Cinder block walls absorb the sealant more than concrete walls and can take longer to properly seal.<\/p>\n Sealing the walls in your basement is definitely a worthy DIY project for those who want to tackle it. As long as you spend time thoroughly cleaning and preparing the walls, application of the sealer is not much different than painting a large room. Of course, if your basement is already finished, you might consider talking to a pro first. The added prep and rebuild work, might be more than you planned for. Another thing to consider is the reason your basement is wet in the first place. Are your gutters not working properly? Do you have an outside drainage issue? You\u2019ll want to solve the cause for water, as much as the water itself.<\/p>\n We recently took all the 70\u2019s paneling off the basement walls and exposed the cinder block foundation. There was quite a bit of work to get the furring strips off the block walls, and prep work took 2 full days to remove the nailers, patch the wall with cement, and prepare for the waterproofing sealer. From there it was a cake walk and the basement was completed in 3-4 days total. <\/main><\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":" $10.25 \/ Sq Foot Installed The average cost to seal interior basement walls is around $6 to $7 per square foot, for DIY waterproofing.
