What is loft insulation?
We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.
- Tank jacket and pipe lagging in the loft
- Area under the cold water tank left clear so it cannot freeze
- Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Dorking
How soon can you visit a home in Dorking?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Do you cover all of RH4?

Do you charge extra to travel to Dorking?
Not normally. Our guide prices include normal travel to Dorking. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will loft insulation make my loft colder?
Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.
Do I need to empty my loft first?
The floor needs to be clear for the insulation to go down. If moving things yourself is difficult, tell us at the survey and we can price clearing and putting items back on raised boarding.
