I flip homes and my most recent project became a much larger undertaking than I'd imagined. I couldn't have completed it without all the help I got from GTA! They explained my options, helped me sort out design decisions and really kept my costs down. We ordered windows, siding, vanities, doors - whatever we could, from them!

We are very happy with our experience working with Rod at GTA Building Supply
! From start to finish the customer service has been top notch. Our new cabinets were delivered on time and in perfect condition. Any questions I had were answered immediately and thoroughly. I highly recommend them for kitchen remodel projects!

In 2017 we built our house and bought the Mid Continent kitchen and bath cabinets. After raising 5 kids and a dog in this house the kitchen cabinets look very, very good. The vanity is in very good shape but the medicine cabinet will have to go. Besides, the med cabinet is now dated. My husband and I would buy these cabinets all over again. They sure have stood up to a lot. Luckily we don't need new kitchen cabinets at this time and we are now remodeling the bathroom. Wish we would have looked at GTA first.
