Well-designed and fitted custom chimney caps will keep debris, birds, and animals from getting into your chimney. Precise measurement and simple design will create a chimney cap that enhances the safety of your home and family.
Step 1 - Measure Your Chimney Flue Top
Measure the length and width of the mortar crown of your chimney, where it narrows just below the flues. Add 1 inch to this dimension for the base size of the chimney cap. If you have more than 1 chimney flue, design a cap to surround all of them, allowing a more exact fit. Add 1½ inches to the base length and width for a mounting flange. This will be bolted into the mortar crown.
Step 2 - Measure the Height of the Flue Tops
Measure to the top of all the flues. The chimney cap must be at least 4 inches higher than the tallest flue top for adequate ventilation of the chimney when capped.
Step 3 - Sketch Your Chimney Cap
Make a detailed sketch of your chimney cap design including the mesh walls, ready for manufacturing in brass or copper.
