Repair
When the brick face starts to flake off or “spall” the proper recommended repair is to rebuild the chimney. Rebuilding is dismantling the chimney brickwork and relaying new brick with masonry cement. The top or crown of the chimney is finished off with a new precast concrete crown for small chimneys. Larger chimneys require a 4″ thick concrete crown with a two-inch drip ledge overhang.
There are many reasons for the damage to your chimney, and all of our technicians are trained to help determine the cause of your chimney deterioration. This will help prevent this situation and hazard from happening in the future.
Relining
Chimney sweeping includes cleaning the chimney cap, flue, smoke chamber, smoke shelf, damper, and firebox areas. Sweeping is done with brushes on a long pole, and falling creosote is caught with a special vacuum.
According to NFPA Code 211 all chimneys shall have a flue liner that can contain and exhaust all by products of combustion including heat, dangerous gases, creosote, and condensation. When the flue liner can no longer perform this intended purpose, it shall be repaired or replaced.
In most instances this is accomplished by using a metal pipe inserted from the top of the chimney down to the appliances. Our technicians are trained to know what type and grade of pipe is best for your chimney’s needs.
Flashing
Flashing is the sheet metal that seals out water where your chimney meets or passes through the roof. It is a critical seal in making certain your chimney is weather tight. Proper flashing will be imbedded into the chimney masonry and consist of both step and counter flashing along with an ice and water shield membrane underlayment.
Flashings are custom made at the job site to insure a proper tight-fitting seal between your roof and chimney. When done properly by our experts, this flashing will keep water out of your house for many years.
