What is loft ventilation?
Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Insulation pushed into the eaves can block that path, which is why we fit ventilation trays. More about loft ventilation.
- Eaves trays where insulation could block airflow
- A note of air leaks from the house that need sealing
- Soffit, tile or ridge vents as specified
Why book with us in Dumbarton
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
How much does loft ventilation cost in Dumbarton?
This work is not an energy-saving material for VAT, so it is standard-rated if VAT applies. Where it is done alongside insulation, the quote shows each part separately.
Building standards in Scotland
In Scotland, insulating an existing loft does not normally need a building warrant, but the building standards still apply. How the rules work across the UK.

Does my loft need ventilation after insulation?
A cold loft needs a path for outside air, usually at the eaves. New insulation must not block it, which is why we fit eaves trays.
Will extra vents make my house colder?
No. The vents ventilate the loft above the insulation, not the rooms below.
