Profile: Fischer Mechanical, LLC is a mechanical contracting company. We installs and repairs gas pipes of all sizes and for all types. Gas pipe is used to transport natural gas safely to the appliance and equipment that requires natural gas to power them. Gas piping can be made up of many different types of pipes. We perform all types of fire caulking for all types of mechanical components. Firestopping is the use of building materials which prevent the spread of flames, heat or hot gases through penetrations in fire-rated walls, ceilings or floors for items such as pipes, ducts, conduits and cables. Fire caulk is designed to expand and fill that void of the melted pipe during a fire.
