"They were on time, and did a great job! I recommend these guys and will use this company again.  The person came for a leaky faucet, but I asked them to put in shut off valves and they ended up helping me because the old disposal was leaking  and I did not know this, so they ended up doing all this work for me and fixing all the problems.  I appreciate the professional help.  I recommend this company.

Basement Waterproofing questions, answered by experts

“Basement waterproofing” sometimes refers to applying a waterproof sealant to basement walls, in which case you would use a waterproof paint, often made of latex. However, there are many methods you can use to waterproof a basement, including exterior drainage systems, interior drainage systems, dehumidifiers, and more. As such, the materials you use can vary depending on the methods you use.

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.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

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.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
