"Wesley was fantastic! We were hoping to be able to extend the gas line from the fireplace to the stove but the piping was too small there to accommodate the stove we purchased. While he said it could be done, and was significantly less expensive, it may not be able to provide the 'power' the stove required. We chose to do it the right way, not the 'cheap' way, pricing was still reasonable for the amount of work that needed to be done. Highly recommended!!"
