"The system was installed so that the pipes were pitched away from the sump, the pipe from the sump outside leaked back into the basement, and the exterior drain wasnt dug to grade so water backed up towards the house. When contacted about the issue, dryzone sent out a tech who confirmed every issue. The company then refused to fix anything without a second opinion. A month after I filed a chargeback, the GM called to "apologize", and made it sound like he wouldnt contest the chargeback, but offered no remedy to the situation. He then contested the chargeback and lied on the chargeback rebuttal. Eventually they settled for a partial refund. Terrible company, dont recommend."

Basement Waterproofing questions, answered by experts

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.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

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.

Your homeowners insurance can cover slab leak repairs, but it really depends on your policy. Some homeowners insurance policies only cover slab leaks caused by natural disasters, while other plans are more comprehensive. You might also want to check your home warranty plan to see if they'll cover the cost of the repairs if one of your appliances caused the leak.
