Chimney Chase Covers

Chase covers are used at the top of chimneys to keep out rain, snow, critters, and everything else.  Most prefab chimneys metal covers start to rust due to rain, ice and snow that sits on the metal for extended periods. When this material start to decay it creates a very acidic condition that eats the galvanized coating off the metal. It can take as little as 5 years of this condition before you very see rust running down the side of your chimney. Eventually the metal starts to pit allowing water to drip inside the chimney structure. You may hear the dripping sounds sometimes when its quiet in the home, after a rain. When you see the rust stains it time to replace the top SOON..  That’s where we come in…

Most chase covers are installed improperly from the start with no supports installed under the cover to hold up the large cap. This creates a instant pool for water and leaves to fall in and this starts the rusting  process. Some covers have nail holes in the chase cover that eventfully starts to leak when the old caulking gets hard and cracks. We can replace the chase cover using stainless steel instead of the regular galvanized metal that will rust. We put two screws in top to hold the cap in place. The holes are filled with marine grade silicon to prevent leaks. The tops have cross breaking to create a dome effect preventing water from standing on the top. Overall this is a better system for a reasonable price.

Add beauty and value to your home. Chase covers in stainless steel or copper, with single or multiple holes, built to your specifications!
