    Deep new mineral wool insulation laid across a loft in Southam
    New mineral wool going down in the Southam loft

    What we found

    The loft had around 50mm of old insulation across 30m² of floor. There was also an old pallet left up there that needed taking out.

    What we did

    • Removed the old 50mm insulation from 30m² of loft
    • Cleaned out between the joists
    • Took away the old pallet
    • Laid 300mm of Knauf mineral wool
    • Kept a 15mm gap at the eaves so air can still move through the roof space
    • Fixed a bag of insulation to the back of the loft hatch to stop heat escaping there

    The result

    The loft went from 50mm to 300mm of insulation in a day, with the eaves left clear for airflow and the hatch insulated. The work comes with a 10-year guarantee.

    A check you can do yourself

    Have a look at your loft hatch. If the back of it is bare board, warm air can escape straight through it, however deep the insulation is elsewhere. A bag of insulation fixed to the back of the hatch, as we did here, is a simple fix.

    Questions about this job

    How much insulation went in?

    We removed about 50mm of old insulation from 30m² of loft and laid 300mm of Knauf mineral wool in its place.

    Why leave a gap at the eaves?

    Air needs to move through the roof space. On this job we kept a 15mm gap at the eaves so the new insulation does not block that airflow.

    Do you take the old insulation away?

    Yes. On this Southam job the old insulation was removed, the space between the joists was cleaned out and an old pallet was taken away before the new wool went down.

    What we do

    Three jobs, done properly, by the same team

    No subcontractors sent out in our name. The surveyor who quotes it sets out the work, and the lads who turn up are ours.

    Spray Foam Removal

    The most common reason people call us: a mortgage lender or surveyor has flagged spray foam in the loft and the sale has stalled.

    • Full removal, open and closed cell
    • Timbers cleaned back and inspected
    • Paperwork accepted by surveyors
    • Loft hoovered out at the end of every day

    Loft Insulation & Boarding

    Old, flattened insulation taken out, the loft space cleaned, and new wool laid to depth. Boarded storage raised above it if you want the space back.

    • Old insulation removed and taken away
    • New insulation laid to current depth
    • Raised loft boarding over the top
    • Carpets and landing covered before we start

    Damp Proofing

    Rising and penetrating damp traced back to what is actually causing it — then fixed outside as well as in, so it does not come back.

    • Damp proof course injection
    • Membranes, salt neutralising and replastering
    • Repointing and external repairs
    • Air bricks and ventilation
    More on damp proofing →

    Loft Boarding

    Raised on legs so the deck sits above the insulation instead of crushing it. Storage you can use without a colder bedroom underneath.

    • Raised leg system, never straight onto joists
    • Full insulation depth kept beneath
    • Tongue and groove storage boarding
    • Hatch and walkway left clear

    Roofing Repairs

    We are in lofts every day, so we see the roof from underneath before anyone goes up top — which is usually where the real fault shows.

    • Slipped and missing tiles and slates
    • Ridge and verge repointing
    • Gutters, downpipes and fascias
    • Eaves ventilation opened up
