What is a loft insulation top-up?
Before we quote we measure the existing layer in several places and check its condition. If it is wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.
- Gaps in the existing layer filled
- Eaves ventilation kept clear
- Cross layer to a total of 270 to 300 mm
Why book with us in Dagenham
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.
Honest about grants
If you might qualify for funding, we tell you before we quote.
Clear contact details
Your quote says who to call with questions before, during and after the work.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.

Questions about a loft insulation top-up in Dagenham
How soon can you visit a home in Dagenham?
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.
Can a landlord in Dagenham book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Is loft work in Dagenham different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Can new insulation go on top of old insulation?
Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
