Business ProfileforJW CONSTRUCTION

We were quoted $65 by ************************* owner of JW Construction in Sept 2021 to construct **** detached garage with a standing attic and mancave room on the backhalf of the building, but we did not get what we ask, were quoted and paid for. We discussed with ****** in great detail when we hited him that we wanted the option to eventually turn the attic into an extra sleeping area for family/guest, but we ended up with literally a crawl space that we can only stand on the stairs and reach so far or crawl into.My husband and I noticed the the roof frame looked too low for a walk in attic the night the framing was just about completed. We called ****** the next day and he stop by the house to discuss the problem with attic, and his only solution after admitting his error was to "finish it out" over the mancave area as well; which meant putting floor boards down. My husband and I both just figured ****** would do right by us because he made a major error and made it know to us that he was a ********* as well, so we thought he would adjust the price at the end but he didn't willingly.****** reluctantly agreed to reduce $2500 from the $13,300 end balance we owed, after telling us "if we need the money go ahead and keep it". We had suggested to him (since he offered nothing or a resolution) to deduct $5000 as a low end resolution for not giving us what we wanted or he quoted us; we had already paid him $50k . If we were to hire someone else to redo the top half of the building to get the storage/sleeping room in the attic it would cost us well over the $5000 we had ask ****** to deduct from remaining balance.
