"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

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

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.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.
