"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

"Contacted Mark within 3 days he was at my home and providing a detailed quote. Might seem small but he was the only one out of 4 contractors who actually measured the space to provide an accurate and detailed estimate. He while discussing what I wanted with me made many recommendations and even mentioned ways to get the job done but at a lower cost. He had the estimate to me within 2 days and it was super detailed and broken down with 3 different ways to complete it. He was on time daily as was his crew. Work areas were cleaned daily. He closed up a broken window for us, redid a dirt floor with drainage and concrete, repointed and waterproofed our basement foundation, ripped out and fully replaced basement access stairs. He even noticed a window that was broken we didn’t and closed it up for no charge. He added a drain to the exterior steps at no charge wasn’t in contract he just knew it was needed, the steps he replaced had asphalt around them and he even repaired the asphalt at no c"

Basement Waterproofing FAQs, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.
