How to Get Rid of Air Leaks Indoors
Do you have air leaks inside your home or have leaky building
Every room in the house has the potential to lose heat from ceilings, floors and the walls, and a little simple
maintenance can make a big difference in the energy needed to heat them.
Doors connecting rooms that are badly hung can be tightened on the hinges to fit snugly and exclude draughts,
and for those that are seldom opened look at an excluder at the foot for complete protection.
Check old fireplaces that may not be properly blocked up and act as a conveyer belt for your precious heat into
the great outdoors.
Sealing at ground and roof level is the best option to prevent heat loss and the entry of moisture and pests. If
you have a servery hatch linking kitchen to dining, look to block it in with glass panels to maintain light but cut
the airflow off. This is important as the moisture released during cooking will make your living area even harder
to heat if not vented correctly.
So much for connecting rooms, now look at the surfaces that are a barrier between you and the outside. Start
from the top and before winter sets in have a good look at the state of the roof. Missing tiles and loose iron will
need only a few hours of DIY efforts to repair, and while you are doing this look for damage under eaves due to
foundation settling and animal activity.
Inside the roof cavity or attic, check for sealing around beams, insulation of hot water piping and light fittings that may need packing
to reduce leaks from below.
After this take a thorough search under the house or in the basement around piping and at the condition of under
floor insulation. Usually the exterior walls in this area will not be insulated and as a result the air temperature
here can be much cooler than in the upper levels of the house. Make sure draughts from this source are not causing
your heating to run excessively just to counteract this cool air.
Walls to the outside should be a natural protection against air leak but they have weaknesses in the windows and
doors that are fitted.
Windows that are cracked and broken should be repaired, even if temporarily until a glazier can attach new
panes. Make sure catches are shutting properly and any warping is adjusted for a perfect seal.
Wooden window frames will shrink in summer as they dry out, and putty may have dropped out causing leaks as
well. Metal frames which act as a heat conductor will lose heat anyway but may need hinge adjustments as well to
Windows should get special attention as they are the thinnest part of the barrier between you and the elements
and prone to damage as a result.
Doors seem solid in comparison, but if not hanging properly will lose substantial amounts of your heating
effort. Check particularly those facing the prevailing winter elements on a regular basis for warp and wear and
Remember that old style key hole is a leak needing attention, not just to reduce heat loss but also for better
security. It is important to realize that air leaks can result in up to 30% of your winter heating just
disappearing through to the world outside!
Your wallet will show the savings that a little attention can bring to your home.
Some venting is important for your home to reduce the build up of dampness but efficient roof
turbine systems are a much better option than a house that leaks like a sieve!
