    I contacted these guys to pour a new driveway on my property. I couldn’t be happier with how it turned out. They did an awesome job. Will definitely keep using them for future projects!

    Quality should be Alex Cosman’s middle name. I originally hired Cosman Construction to build me a rustic screened deck, and the project evolved into a wonderful 3-season glassed-in addition—far exceeding my expectations! Their attention to detail is extraordinary, and their rigor in supervising subcontractors is awesome. Finally, communication was excellent: they always let me know what to expect and consulted me along the way. In my experience this is a rare and welcome quality for contractors. I’m a professor by trade, and overall, I would give Cosman Construction a resounding A+!

    Alex conducted himself very unprofessionally. Would advise against using.

    Asked for an estimate for repairs. Without seeing the property, he told us over the phone our deck was probably going to fall off and to get someone else.
