Finding that draught

sidcon

Ok so bought a bungalow that was G rated on BER in 2012 and for the last few years while living in it we have done a number of improvements to improve it. Attic insolation , triple glazing whole house, central heating. We have one major extension plan for next year to convert the attic making the house double in size. Pp approved already.
The last few days however as its getting colder we're noticing a draught but have done nothing this year so baffled as to were its coming from and where we are loosing heat from.
Short of getting a BER assessor in, anyone recommend what I can do to find where the gaps are?

Check around your skirting boards -I had a similar problem some years ago. A badly installed wall vent and gaps between the slabs and floor, meant a breeze was blowing through the bottoms of the skirting boards. Might not be this but worth a look. Carefully bring a lit candle and see what happens the flame.

Probably not diy but may pay dividends when you do your conversion would be to have the house tested for airtightness / heat loss in general*. This will
1. determine exactly where your air leaks are now, but more importantly
2. educate you on the whole concept of air tight construction which will have ramifications for your attic conversion.

*Note this is a completely different kettle of fish than a ber assessment, so don't confuse the two.

No fully fitted stove fire so sealed once door is closed.

Thanks, how did you find out it was around the skirting. Or is it as you say literally a lit candle.

Cheers, with 2, is this condensation concerns?

Yes, absolutely, so appropriate ventilation required. All this is part of the education process.

Where does it draw air from?

It was the breeze! We had some dampness in the room and went to investigate. We made the vent better (there was no pipe running from inside to outside, just vent openings on both inside and outside walls); sealed it much better around the pipe and then sealed the gap between the "short" slabs and the floor. Haven't had a problem since, fingers crossed.

Had draughts coming through gaps in reclaimed timber floor and skirting.

Used a stretchy neoprene filler called Draughtex.

Have full roll leftover up on adverts

Incense sticks are a good indicator of draughts instead of a candle.
