Your home is leaking heat. And you’re paying for it every single month.
Most Perth homes aren’t properly sealed — they’re full of gaps around doors, windows, cornices, exhaust fans, and ceiling penetrations that let cold air flood in during winter and hot air pour in during summer.
The cost? An estimated $1,200+ extra per year in heating and cooling. And draught sealing is one of the highest-return improvements you can make to an existing home.
Where drafts are entering your home right now:
→ Under and around external doors
→ Gaps around window frames and sills
→ Exhaust fans and rangehood ducts
→ Cornices and ceiling penetrations
→ Powerpoints on external walls
What you can do right now — no renovation needed:
→ Door seals and sweeps — under $50 per door
→ Weatherstripping around window frames
→ Draught excluders on exhaust fans
→ Foam backing rods in cornice gaps
→ Powerpoint insulation pads
One thing most people get wrong: adding ceiling insulation to an unsealed home barely helps — the air bypasses it. Seal first, then insulate. That’s the correct order, and the highest return.
And if you’re building new? A Passive House is designed airtight from day one — tested to less than 0.6 air changes per hour. The average Perth home leaks at 10–15× that rate.
