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.

Questions about loft insulation for an older house in Watford
Can you visit Watford outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
Will I get a written quote for work in Watford?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
What do I need to do before you arrive in Watford?
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.
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.
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.
