"When I called the mold company for my lab results. They gave me a person named Ricardo Echeverria, Senior Mold Analyst to call for the results. He verbally told me that the cause was something like a remodel, construction going on. There was a red flag for a VOC called Methylene Chloride--Banned outdated paint. I sent Ricardo and email asking if I can have a report of what he said in writing. I only received a contaminants list. I said, I am not a scientist and do not understand the lab results.I never received a response back from him. I called Jeremiah Bancroft a few times and asked for a written explanation of the causes. He could not supply me with a written explanation because it was a legal issue. I asked for his help. I need your help. Jeremiah said, go to your primary care for a doctors note. That was the last time I spoke to him on September 19, 2024"

Drycrete Waterproofing is the premier full-service basement waterproofing company. We specialize in interior drainage systems, sump pump installation and servicing, foundation crack injections, slab removal and basement lowering. We are the most trusted source for guaranteed solutions to wet and damp basements in homes or businesses in Massachusetts. Drycrete uses the best available products on the market and our expert process transforms a wet undesirable basement into a safe, dry and usable space. Our company values are based around Integrity, Innovation, Craftsmanship & Compassion.

"I moved into a 2 year old house to immediately find water seeping into the basement. I found some signs of it around the baseboard moldings. I called a couple of companies, one of them Drycrete and another, an interior french drain company. The french drain company wanted to jack hammer my finished basement and install one of their systems, an additional sump pump, and a ton of exterior work for pump discharge. That was going to cost 15-20k. Drycrete on the other hand, walked around the perimeter and noticed the obvious - foundation cracks. Those are cheap to fix, but not a guarantee. In any case, I decided to start from the top down, cracks first, 20k french drain later. The process for a crack seal is pretty straight forward and if I wasn't as pannicked I would have attempted it myself. They used Poly to inject into the crack and it worked. The basemet is dry. My sheetrock is open and the wall is still bare from the spray foam along the crack lines. I constantly measure the moisture content in the baseplates and it's slowly getting back to normal. But the moral of the story is - whatever company you bring on to a job site, whatever sperialty it is that they do, that's the solution they will likely propose to you. Drycrete did a good job as far as getting the right diagnosis. If I had to change anything about my experience with Drycrete, maybe I woould have requested for them to put up Zipwalls around the work area. Drywall and concrete dust went everywhere. Overall, good work y'all."

"Peter and his crew were great. Peter was prompt in responding to my inquiry and came out to the house to walk through the lead report and work that needed to be done with me. He gave me a number of options for remediating things and showed me where we could do things in a less expensive manner--explaining the costs and benefits of the different approaches. For example, in one area he told me it was going to cost a significant amount for him to remediate and that it would ultimately be much cheaper for me to replace a section of wood railing instead of remediating the paint. This was to my benefit and his detriment, so I really appreciated it. His crew remediated 15 historic windows and they fixed some cracked panes of glass without my even asking. Peter was very fair, always in communication, and they completed the work promptly and professionally. I highly recommend."
