    What we found

    The loft insulation was thin and patchy, with old debris left between the joists.

    What we did

    • Removed 35m² of old insulation and debris, back to the bare joists
    • Laid 100mm of mineral wool between the joists
    • Cross-laid 200mm over the top, for a full 300mm
    • Kept the eaves clear so the roof space stays ventilated
    • Bagged the waste and took it away

    The result

    A full 300mm of new insulation across the loft floor, laid evenly without squashing it. Finished in a day and covered by our 10-year guarantee.

    A check you can do yourself

    Pop your head into the loft with a tape measure. If the insulation doesn't come up well above the joists, it's worth a look.

    Questions about this job

    Do you remove old loft insulation first?

    On this Leeds job, yes. We cleared 35m² of old insulation and debris back to the bare joists before laying the new rolls.

    Why is the top layer cross-laid?

    Laying the second layer across the joists covers them, so there are no gaps where the timber shows through.

    Why keep the eaves clear?

    Air needs to move through the roof space. Keeping the eaves clear lets it ventilate, which helps prevent condensation.

    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
