"When we purchased our home in 2017, there was already a crack across the top 2 segments of the driveway where that area had sunk quite a bit. Besides the cosmetic issue, we felt this subsidence was also a tripping hazard. After researching online and using Angi, I found GROUNDWORKS (formerly FSS: Foundation Support Specialists) who came out to give an estimate. Ricardo showed up on time with advanced warning of his ETA. He was thorough and left me with a color-coded bid. Some of the driveway and sidewalk leading to the front door were going to be lifted, and some parts stabilized using the foam injection method. Even though I received bids from 2 other companies, I chose GROUNDWORKS for their 5-year warranty and mid-level pricing. All companies were 4.5 stars or higher on both Google and Angi. On the job day, they arrived on time. The job was completed in about 2 hours. I am very happy with the results."

Basement Waterproofing questions, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to water-damaged concrete.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

It’s not safe to live in a house with water damage until a trained professional gives you the all-clear to return. Mold can grow within one to two days after water damage and weaken your home’s structural integrity. Always have your home inspected after water damage to ensure it’s safe to live in.
