Writing this as the concrete is still drying on new basement waterproofing/sump pump. Brett came out for the initial bid and extremely knowledgeable and professional. The system was of good quality, and at a competitive price. But what really blew me away was the install crew and what a great job they did! Courteous and professional, finished right on schedule too.

First class all the way, from Brett selling to Todd and Brad doing the install. They cleaned up, they even put down grass seed! Who does that? Apparently, Stratum! Best of all, they didn’t try to gouge me on the price for my egress windows! Highly recommend and would use for ANY project at ANY time!

Stratum put in an egress window for our home. They were very conscientious of how they performed the work and kept us informed about our job’s progress. We would use them again and had a pleasant experience with all who helped.

Had structural issues with a basement wall. Spent a year getting quotes and info on a fix. Stratum were the first company I went to, since I seen they had good reviews, that’s what initially drew me to them. After getting more information from structural engineers, and also other bids, I went back to them to do the work. After a year of collecting data, it was obvious to me, that they were selling me a solution and not just a product like the other contractors I approached. I’ve been really impressed with them from working with their office personnel to the men working in the field. I can say without doubt, they derseve their 5 star rating. If you have work to be done on your house in a structural sense, you should definitely give this company a call.

After receiving 3 bids, I decided to hire Stratum Structural Systems. I hired them for two jobs. a minor crack repair for one property and then a complete drain tile system and extend the downspouts away from the foundation for another property. Their pricing was competitive, and Matt is extremely knowledgeable and professional. The crews who completed the work were on time and finished the work as promised. They were great, and we will definitely be referring them and using them again!
