G J Builders has done 4 separate projects for us including an addition custom gourmet kitchen, massive decks, pool area pergolas and custom office / music room. They are reliable, ALWAYS on time, and the quality of the work is beyond expectation. There is no arguing with them, they do what they say and bend over backwards to keep you happy and on budget. I do not worry when they are on the job, you won't either.

I too was happy with GJ Buiders initial work on two separate jobs. Fortunately David C, who gave them a glowing review, didn't have to deal with their unprofessional customer service with regards to a defective workmanship issue. GJ Builders, specifically Roger (not Wally or Mark) had the chance to step up and do the right thing and be a"hero" but instead chose to be a "zero." Only after being told by an independant third party that the defective workmanship was in fact their responsibility did they begrudgingly fix the problem. So to be fair, do they do good work, yes; however, If you do choose to use them, pray for no issues.
