"CT basement did a phenomenal job finishing our basement and we could not be happier with the results. They made every step of the process from design to the finished project simple and straightforward, everybody was easy to work with and made our opinions and needs the top priority and they were able to perfectly translate our vision into the final product. This was a fairly large project involving finishing 1200sq ft with an office, gym and full bathroom and their experience and expertise was obvious. They definitely understand the specific needs of a basement while making it look like any other room in the house. We would use them again in a second, we’ve even been joking about tearing down the rest of the house and just living in the basement!"

"We hired VL Construction for several projects on our home, including installing a drywell, leveling and paving our dirt crawlspace, repairing cracks in our stucco, and resurfacing and repainting the exterior. Across all of it, the work was excellent. What stood out most was how thorough they were; beyond the scope of the original work, they identified several additional issues that likely would have gone unnoticed by other contractors, and addressed them proactively rather than leaving us to discover problems later. Despite the added scope, we never felt overcharged; pricing was fair and honest throughout. We'd use them again for future projects and would highly recommend them."

Basement Waterproofing questions, answered by experts

Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn’t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
