We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.

Questions about a loft insulation top-up in Brentwood
Will I get a written quote for work in Brentwood?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you charge extra to travel to Brentwood?
Not normally. Our guide prices include normal travel to Brentwood. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Brentwood book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
