"We contacted them for an estimate on our basement.  Initial phone call and connection went well, very professional, quick, and prompt.  Once the rep was at our home he went into a "pitch" vs. listening to what we said we already knew we wanted.  We even had a sketch.  Eventually we went to review the space, take measurements, etc.  We then started to pick out materials......he brought all the samples but then put together an evaluation based on square foot and overall price of our home and used that based on the square footage of our basement to determine a "fair" value........which was $100/sq ft.  That would have equated to over $100,000 basement.  Then he said how much "fairer" their price was at the quoted rate.  We were too far apart in our estimates which is fine with me, but at the end he said if I obtained a quote that was lower ~ to give him a call and they'd see what they can do.  At that point, I believe "no thanks".  Give me your best price up front.  The entire visit took almost 3 hours.  It was a big waste of time for all unfortunately as we had no intent to spend that much.

Basement Waterproofing questions, answered by experts

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

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.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.
