About this service
We look for the source of the moisture, treat any mould on the timbers, improve the airflow and seal the gaps letting damp air up from the house. Then the insulation goes back in at the right depth.
What’s included
- A look at the timbers, felt and insulation
- The source of the moisture found and explained
- Mould on timbers treated
- Ventilation improved where it’s lacking
- Wet or spoiled insulation replaced
- A written quote first
We price the job after looking at your loft. You get a written quotation before any work is agreed.
Why it happens
Warm, damp air rises from the house into the loft through the hatch, around pipes and from fans that vent into the roof. When it meets cold timber or felt, it condenses. Over a winter that can mean drips, damp insulation and black spots on the wood.
What we do about it
First we work out where the moisture is coming from and why it isn’t getting out. Then we treat the affected timber, open up the eaves or add vents, seal the routes the damp air takes, and replace any insulation that has got wet.
When it’s something else
Sometimes damp in a loft is a roof leak, not condensation. If that’s what we find, we’ll tell you plainly so you can get it fixed before the loft is insulated again.
