What is loft ventilation?
Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Where there are no vents, we add soffit vents, tile or slate vents, or ridge vents, depending on the roof covering and the underlay. 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 Windsor
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.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
How much does loft ventilation cost in Windsor?
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 regulations in England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.
Questions about loft ventilation in Windsor
What do I need to do before you arrive in Windsor?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Do you take on jobs outside Windsor?
Yes. We also work in Slough and Maidenhead and elsewhere in Berkshire.
Will I get a written quote for work in Windsor?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Will extra vents make my house colder?
No. The vents ventilate the loft above the insulation, not the rooms below.
My bathroom fan vents into the loft. Is that a problem?
Yes. It pumps warm, wet air straight into the coldest part of the house. The duct should run to outside through a vent tile, soffit or wall.
