Basement Waterproofing questions, answered by experts

Preventing water accumulation involves regular inspections, maintaining effective drainage systems, ensuring proper roof maintenance, and taking preventive measures against heavy rainfall or floods.

Finishing an unfinished basement adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Yes, if your crawl space is prone to humidity, a dehumidifier can help keep it dry. For use in a crawl space, you’ll need a high-capacity and high-efficiency dehumidifier with built-in air filtration. It’s also wise to purchase one with a self-draining feature. Otherwise, you’ll need to climb into the crawl space to empty the dehumidifier.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.
