Fireplace and Chimney Capping Services

To save up to 15 percent of your monthly energy bills, and make your home warmer, a lot of insulation modifications must be done to improve on energy efficiency and building durability. Sealing gaps (weather-stripping) around your doors and windows is very vital in the energy saving strategy. The fireplace plays a significant role of sending a large amount of warm air up the chimney and must be sealed to retain as much heat as possible.

Most fireplaces are constructed using an iron frame, throat damper and a door responsible for opening and shutting of the fireplace. These three components are capable of reducing heat loss but are not as efficient as an airtight seal. Glass has been used in some homes, but this is not as ideal as a chimney cap that has been proven to provide an airtight seal.

To get a tight seal, chimney caps are installed on top of the chimney and are then loaded with spring. The steel cable must be released to allow opening of the lid. The cable then goes all the way to the firebox through the damper at the chimney top. Replacement of the chimney cap depends on how often the fireplace is used. Frequent usage may warrant frequent replacement.

In case of a chimney fire or if there is a failure of the steel cable, the stays in an open position. The chimney caps are also responsible for preserving the masonry flue, preventing leaks and keeping out the rain. The chimney cap is capable of stopping downdrafts and also helps in keeping pests like birds and squirrels from entering the house.

Available sealing dampers

Sealing damper, also known as top damper is attached to the top of a flue and replaces the throat damper function. The throat dumper is always located between the firebox and the smoke chamber at the bottom of the flue. The throat dampers are installed as a replacement for irreparably damaged throat dampers in the chimneys.

We, Home Insulators, offer two varieties of dampers, the most common options, and the best materials in the market. One type has a lid that pivots, while the other type has a pop-up lid. The type with a lid that pivots has a chimney cap, comes with a mesh animal guard and is made of cast aluminum and stainless steel. The type with a pop-up lid is however made of aluminum and can fit in both square and round flues.

The two types of dampers have silicon rubbers which perform efficiently. The pivoting dumper is however not visible from ground view because it is less conspicuous. Top sealing dampers can also be used in wood stove inserts and wood stoves in a fireplace.

In an event that this happens, a round flue, preferably, stainless steel is threaded, and it goes through the throat damper in the fireplace. This results in the leaving of a notable hap around the outer section. Even though fireproof insulators have been used to stop warm air from escaping, they are not as efficient as a top-seal damper which provides an airtight seal.
