"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

Basement Waterproofing questions, answered by experts

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
