Do you have rust running down the side of your chimney and wonder where it’s coming from?
Over the years, the metal covers on most pre-fab chimneys start to rust due to moisture (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 starts 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 see rust running down the side of your chimney. Eventually, the metal starts to pit (rust through) allowing water to drip inside the chimney structure. You may hear the dripping sounds sometimes when it’s quiet in the home, after a rain. When you see the rust stains, it is 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 an instant pool for water and debris to fall in, starting the rusting process at the first rain. Some covers have nail holes in the chase cover that eventfully start to leak when the old caulking gets hard and cracks.
We can replace the chase cover using stainless steel or KolorKlad instead of the regular galvanized metal that will rust in time. When installing the new chase top, we only drill holes for screws in the side flange not on top. We drill 2-3 holes in each long side flange about 18 inches from each end and install stainless steel screws to hold the cover in place. The tops have cross breaking to create a dome effect, preventing water from standing on the top. The existing cap is cleaned and painted to look like new. We use a special glue to hold down the cap – not screws like before – preventing another water leak source. Overall, this is a better system for a reasonable price. Plus stainless steel chase covers have a lifetime warranty, and KolorKlad tops have a 25-year warranty.

Stainless steel is still one of the materials we recommend because it’s a more durable material for use outdoors. The metal is stronger and, over a long period, looks like new. As you know with your kitchen sink, stainless will not rust.
We also recommend another product, KolorKlad, that is a good alternative to stainless steel. It has a 25-year product warranty and comes in a number of different colors with a very durable finish. The most basic are Black, White, Sand, Bronze, Red, Green, etc. We can get close to most trim colors or, if you want to be different, go with a different, complimentary. KolorKlad is made from the same material that metal roofs are made out of, and this material is much more cost-effective than stainless steel.
Give us a call today, and we will come by to take a look at your chimney and give you a price on replacing the old rusted top with a new model. We can also give you a price on regular galvanized and paint grip coating if you want a cheap fix (no warranty on these options).
Chase cover replacements start at around $550.00 for galvanized, $675.00 for KolorKlad and $800.00 for stainless steel. Actual pricing depends on size, material requested, and height of chimney. Most customers opt for KolorKlad, and every so often we are asked to make a copper one. 🙂
Prices for copper are highest, with stainless next, then KolorKlad – a good buy, and galvanized is the lowest cost with the lower-quality metal.
Stainless steel and sopper chase covers have a lifetime warranty against rust, corrosion and defects. KolorKlad chase covers carry a 25-year warranty against rust, corrosion and defects (we recommend this one most often). Galvanized has a one-year warranty against rust and defects only.
All tops come with a one-year workmanship warranty on the installation of product.
Hope this helps. For more info or to schedule for replacement call us at 919-772-8110.
