“We are pleased and recommend J&J Contractors for their high standard of skill, care, and attention to detail. Their skilled trades did exceptional work on our project. We remodeled an existing one-bathroom home and constructed a second bathroom from a covered porch into a beautiful ensuite bathroom.
J&J Contractor’s draftsman, Tim Z., along with designers Taylor and Baily, turned the dream into two bathrooms that far exceeded our expectations. Our project manager (Jeff D.) kept the project moving and on time. We had several bids and ideas from other contractors and chose J&J Contractors because they presented the best vision and had the expertise to complete our project.”
