Loft insulation in Crouch End

Yes, and it is cheaper done together. The one thing to check is the hatch: many older Crouch End openings are too small for a ladder to swing through safely, so enlargement may be needed. We measure at survey and price it up front. See loft ladders.

Not if it is done properly. Insulating the floor makes the roof space colder, so moisture condenses more readily — the defence is the ventilation path at the eaves. Blocking it with insulation is what creates damp lofts. We keep it clear on every job. Our ventilation guide explains the mechanism.

Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Crouch End lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.

Usually, and often noticeably. Loft insulation depth is recorded directly by the assessor, so increasing it from 100mm to 270mm generally moves the rating. We hand over product documentation and declared performance figures so your assessor records what is actually there.

Absolutely. The only wrong way to do it is to board flat onto the joists. We raise the deck on battens or loft legs, board it in tongue-and-groove panels and leave the eaves clear so the roof keeps ventilating.

Pipes get lagged and the tank gets insulated on the sides and top only. Leaving the base open is deliberate — it is the only thing preventing a frozen tank in a hard winter.
