We would like to remodel a second floor fireplace (gas insert type) using a synthetic stone veneer. Based on the sample left us by the mason, I've calculated a weight of just over 1,000 lbs. We would prefer this to the Air Stone product, which would weigh approximately 275 lbs. The fireplace sits atop a second fireplace (gas insert type) in the basement. How can we know if the interior second story wall will support the weight?
If the stone is flat against the exterior wall, and it is really just a 2" or 3" veneer, you should have no problem. The weight itself is easily handled by the exterior wall framing. If the fireplace wall and stone cladding are toward the interior of the room and are positioned over joists, the joists underneath will have to be reinforced... not an easy or cheap thing to do! Give us a call for an on-site inspection if you feel we haven't understood your specific situation adequately.
