They were kind and understanding, as we needed to remove a tree before they could complete the work. Also, they pointed out some damaged irrigations from the tree removal and paused their work to allow us to make the necessary repairs. It was a great experience and ETREMELY nice people.

We had a cracked cement walkway over a basement area that was flooding. The walkway had been…read morepreviously repaired and has been deteriorating with water seeping into the basement. Mike and his team cleared the cracked cement down to the aggregate, resurfaced it and graded it to keep the water away. The result was a really neat repair that blends perfectly into the existing walkway. The crew arrived on time, practiced social distancing, were easy to communicate with, and cleaned up everything. I will definitely use this company again.

The work crew left the basement cleaner than they'd found it, and the project manager popped in from time to time to keep me posted on timing and how things were going. From the initial estimate to final billing, everything went really smoothly, and everyone we came into contact with is thoughtful, professional, easy to work with, and excellent at what they do. Thank you!

When Cliff showed up to assess our leaky finished basement (which took on water during heavy rains,…read morelikely at the cold seam between the foundation (1927) and the rat slab (1980's?)), I was a little skeptical. Other contractors visited in decaled trucks, carrying professional letterhead and selling a "comprehensive" (and expensive) system of trenches cut into the slab, plastic sheeting behind the drywall (and a lot of drywall repair) and a sump pump. Cliff arrived wearing camouflage cargo shorts and a tank top, with an entirely different idea: a drain tile. Due to some mixed reviews on Yelp, I asked to speak with three references, all of whom showered "A" Waterproofing with praise (to a surprising extent). I also read up on drain tiles on Green Building Advisor -- they checked out. So, I awarded "A" Waterproofing the job, and I still feel lucky that I did. In less than a week, "A" Waterproofing had installed and patched over the drain tile. They wrapped the system in geotextile (recommended on Green Building Advisor) despite their patient debate to the contrary. I appreciated the flexibility. Likewise, they were gracious with my requests to add clear-out caps, and to use 45º joints instead of 90º joints so as to improve flow to the drain. The changes may not improve performance, but it gave me some ease. We had 2.5" of rain within 30 hours later that fall, an amount that certainly would have flooded our basement. Imagine our relief and delight when we couldn't find any moisture at the usual spots! Finally, we could rest easy when big rain loomed on the forecast. Our sole point of friction came when "A" Waterproofing cut a decommissioned pipe that lay in the path of their drain tile. Something seeped out and stained our new concrete. "A" Waterproofing took responsibility and paid for the clean up without argument. That demonstrates commendable integrity. I heartily recommend "A" Waterproofing if your basement seeps during heavy rains. Their work cost thousands less than competing systems, which now seem absurd overkill by comparison and would have involved a ton of drywall repair. PS - Before "A" Waterproofing wrapped up, we also had them install 30' of fence along and on top of a concrete retaining wall, and install about 50' of french drain along our foundation. They completed both projects efficiently and satisfactorily.
