Chase tops for Pre-Fab Chimneys
Do you have rust running down the side of your chimney and wonder where is that stuff coming from...
	Over the years most pre-fab chimneys metal covers start to rust due to rain, ice and snow that sits on the metal for extended periods. Along the way pine straw and leaves land on top as well. 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 tops are improperly installed from the start. They are made from thin galvanized sheet metal 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 starting the rusting process at the first rain.. 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 black cap in place. The holes are filled with marine grade silicon to prevent leaks. We drill 2-3 holes in each long side flange about 18 inches from each end and install stainless steel screws to hold cover in place. 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. Plus it has a lifetime warranty.

We used to recommend stainless steel because its a more durable material for use in outdoors environment. The metal is stronger and over a long period looks like new. As you know with your kitchen sink stainless will not rust. However we now recommend another product that we think is a good alternervinve to Stainless Steel in light of the recent price increase for Stainless Steel.. The product is called "Color-Clad" has a 25yr product warranty and come in a number of differnet colors. The most basic are Black, White, Sand, Bronze, Red, Green etc.. we can get close to most trim colors or most times it better to be diffenent and not try to match the color.. Color Clad product is the material used for metal roof's, its prefinished with a the color you choose and made to order and is a very durable finish. Give us a call today, we will come by, take a look at the chimney, and give you a price on replacing the old rusted top with a new stainless steel model. We can also give you a price on regular galvanized and paint grip coating if you want a cheap fix. This material has no warranty. Chase cover replacements start at around $425.00 for galvanized, $495.00 for color clad and $615.00 for stainless steel. Actual pricing depends on size and material requested and height of chimney. Most customer opt for Color Clad and every so often we get to make a copper one.. :) Prices for copper is highest, with stainless next, then "Color- Clad" a good buy, and galvanized lowest cost, lower quality metal. Stainless Steel and Copper chase covers have a lifetime warranty against rust, corrosion and defects. "Color-Clad" chase covers carry a 25yr warrenty against rust. ( we recommend this one most often.) Hope this helps, if you need more info or to schedule for replacement call us at 919-772-8110
