This is the company you want to waterproof your basement and install an egress window! Probably not the cheapest, also not the most expensive. But if you want it done right and never need someone to come to your home again for water issues, these are the guys. We did not have many water issues to begin with, just some efflorescence and mold. Had it done to finish the basement in the future. Their office communication is outstanding. They were supposed to start the project the day we got 8”+ of snow. For obvious reasons they postponed and found a different week that worked with my schedule. Amazed that they finished all of this is 2.5 days.

Bravo.
Adam Basement was recommended by a friend. Their service was outstanding at every touch point.
The estimator arrived on-time, knowledgeable and so kind. He tested and provided choices. The price was fair.
The installer arrived on the same day and efficiently installed the new pumps and backup system. The worksite was clean and he taught me to easily test the new pumps (push a button).
Excellence should be acknowledged.

We had Adam Basement install a waterproofing system in our basement and crawlspace, install an egress window, and encapsulate our walls. They did a fantastic job. They were very thorough and left me impressed with their quality of work and attention to detail. They even fixed things they came across without me needing to ask. Doing it right just seemed important to them.
