What is different about insulating an older home's loft?
We work from crawl boards spanning several joists so the ceilings are not loaded, check for loose plaster keys before anything is laid, and usually recommend vapour-open insulation such as sheep's wool or wood fibre. Unfelted slate roofs are naturally well ventilated, but they let in wind-driven rain and snow, which the insulation has to cope with. More about loft insulation for an older house.
- Ceiling-safe working from crawl boards

Questions about loft insulation for an older house in Northamptonshire
Are your prices the same across Northamptonshire?
Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.
How do I book a survey in Northamptonshire?
Send the form or call us. We call back to agree a time and confirm it in writing.
Can loft insulation damage lath-and-plaster ceilings?
It can if people kneel between joists or if the ceiling is already weak. We work from boards and check the ceiling first.
What is the best loft insulation for an old house?
Usually a vapour-open material such as sheep's wool or wood fibre, laid so moisture can still move. Mineral wool is also vapour-open and works in many period lofts at lower cost.
