"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 best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.
