Caulking Services
• Caulking services are performed as a way to increase the energy
efficiency of a home or building. It is also useful to prevent the
infestation of certain insects, such as ants and rodents.
• Caulking services can also be used when installing new home
appliances. Placing caulking along the base of the appliance ensures
that it remains in place; this reduces strain on the appliance, saving
time and money by avoiding the hassle of having to do major repairs
later or replace the appliance.
• Sometimes in construction, the workers will install a ―backer rod‖ in
addition to caulking. This is a piece of foam that is placed behind
the caulking bead to provide more elasticity and reduce caulking
consumption. The backer rod helps to determine the thickness of the
caulking and the shape of the caulk that is placed on the joint or gap.
It forces the caulking into place and provides a more solid sealant
and a better bond.
• The backer rod helps keep the caulking from attaching itself to the
bottom of an opening, an unwanted phenomenon known as a ―three-
sided-bond‖. The caulk is instead adhered to the opening in an hour-
glass shape; this creates a more flexible hold which is less likely to
tear.
