Chimney Rebuilding Repointing Contractor Elberon NJ 07740

chimney is a structure which provides ventilation for hot flue gases or smoke from a boilerstovefurnace or fireplace to the outside atmosphere. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into thecombustion in what is known as the stack, or chimney, effect. The space inside a Elberon NJ 07740 chimney is called a flue. Chimneys may be found in buildings, steam locomotives and ships. In the United States, the term smokestack (colloquially, stack) is also used when referring to locomotive chimneys or ship chimneys, and the term funnel can also be used.

The height of a chimney in Elberon NJ 07740 influences its ability to transfer flue gases to the external environment via stack effect. Additionally, the dispersion of pollutants at higher altitudes can reduce their impact on the immediate surroundings. In the case of chemically aggressive output, a sufficiently tall chimney can allow for partial or complete self-neutralization of airborne chemicals before they reach ground level. The dispersion of pollutants over a greater area can reduce their concentrations and facilitate compliance with regulatory limits.

Today, Elberon NJ 07740 chimney sweeps still maintain a thriving new industry in many parts of the world. The industry has expanded from the maintenance of wood-burning fireplace and appliance venting systems to include venting for many types of heating appliances. Venting systems for Heating Oilnatural gaswood and pellet burning appliances, including building furnaces and space heaters are maintained by modern chimney sweeps. The standard chimney brush is still used, along with more modern tools (such as vacuums, cameras and special chimney cleaning tools), although most sweeps are done from the bottom of the chimney, rather than the top, to prevent the dispersion of dust and debris in Elberon NJ 07740.

Most modern chimney sweeps are professionals, and are usually trained to diagnose and repair hazards along with maintenance such as removal of flammable creosotefirebox and damper repair, and smoke chamber repair. Some sweeps also offer more complicated repairs in Elberon NJ 07740 such as flue repair and relining, crown repair, and tuckpointing or rebuilding of masonry chimneys.

Repointing is the process of renewing the pointing (the external part of mortar joints) in Elberon NJ 07740 masonry construction. Over time, weathering and decay cause voids in the joints between masonry units (usually bricks), allowing the undesirable entrance of water. Water entering through these voids can cause significant damage through frost weathering and from salt dissolution and deposition. Repointing is also called pointing, or pointing up, although these terms more properly refer to the finishing step in new Elberon NJ 07740 construction.

Masonry units are typically laid in a bed of mortar. The process of placing a masonry unit in a mortar bed causes the mortar to be extruded between units. This excess mortar is cleared and shaped before the mortar hardens. In some cases, the bedding mortar is meant to be seen and the mortar joint is immediately given a finish profile. In other cases, especially where the mortar is pigmented, the bedding mortar is removed from the joint before it hardens (usually a depth that averages about one inch), and then pointing mortar is applied in the void and shaped with a finish profile.

A characteristic problem of chimneys is they develop deposits of creosote on the walls of the structure when used with wood as a fuel. Deposits of this substance can interfere with the airflow and more importantly, they are combustible and can cause dangerous chimney fires if the deposits ignite in the chimney.

Heaters that burn natural gas drastically reduce the amount of creosote buildup due to natural gas burning much cleaner and more efficiently than traditional solid fuels. While in most cases there is no need to clean a gas chimney on an annual basis that does not mean that other parts of the chimney cannot fall into disrepair. Disconnected or loose chimney fittings caused by corrosion over time can pose serious dangers for residents due to leakage of carbon monoxide into the home. Thus, it is recommended—and in some countries even mandatory—that chimneys be inspected annually and cleaned on a regular basis to prevent these problems. The workers who perform this task are calledchimney sweeps or steeplejacks. This work used to be done largely by child labour, and as such features in Victorian literature. In the Middle Ages in some parts of Europe, a crow-stepped gable design was developed, partly to provide access to chimneys without use of ladders.

Masonry (brick) chimneys in Elberon NJ 07740 have also proven to be particularly prone to crumbling during an earthquake. Government housing authorities in cities prone to earthquakes such as San FranciscoLos Angeles, and San Diego now recommend building new homes with stud-framed chimneys around a metal flue. Bracing or strapping old masonry chimneys has not proven to be very effective in preventing damage or injury from earthquakes. It is now possible to buy "faux-brick" facades to cover these modern chimney structures.

Other potential problems include:

  • "spalling" brick, in which moisture seeps into the brick and then freezes, cracking and flaking the brick and loosening mortar seals.
  • shifting foundations, which may degrade integrity of chimney masonry
  • nesting or infestation by unwanted animals such as squirrels, racoons, or chimney swifts
  • chimney leaks
  • drafting issues, which may allow smoke inside building
  • issues with fireplace or heating appliance may cause unwanted degradation or hazards to chimney
