Loft Insulation in Manchester: 100m² Reinsulated to 300mm

The upstairs rooms never felt warm and the heating bills kept climbing. Rather than adding insulation blindly, the homeowner wanted a survey first — so we looked at what was actually up there before recommending anything.

    Why they called us

    The upstairs rooms never felt warm in winter and the heating bills kept climbing. The homeowner suspected the loft was losing heat, but wanted a survey-led recommendation rather than adding insulation blindly.

    Their goal was simple: make the upstairs rooms feel warmer in winter and cut the heat going out through the loft.

    What we found on survey

    The 100m² loft had thin and uneven insulation, with compressed areas that no longer gave consistent thermal coverage. The survey also checked that eaves ventilation could remain open once the insulation depth was increased.

    That second point matters as much as the first. Insulation that is patchy or compressed leaves weak points above occupied rooms, making the house harder to heat — but increasing depth without protecting ventilation can raise condensation risk, so the specification had to address both.

    What we did

    We prepared the loft and laid mineral wool evenly to a measured 300mm depth across the full 100m², over two days. Eaves ventilation was retained, reflecting Building Regulations Part L guidance and BS 5250 moisture-control principles.

    The result

    Continuous 300mm mineral-wool coverage with the ventilation route kept clear. The homeowner received a clear specification for what had been installed, and a 10-year workmanship guarantee.

    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
