South London loft specialists
Loft insulation, boarding, ladders and complete makeovers for homes throughout Wallington. Free survey, fixed written quote, no call-out charge — and an honest answer if your loft turns out not to need anything.

Why it matters
Which is why a free survey is worth half an hour of your time — the measurement itself usually settles whether a Wallington loft is worth spending anything on.
Wallington's homes
The roofs over Wallington are mostly slate and tile pitched roofs, with many terraces running unbroken for a considerable length, and they were built during the 1860s through the 1930s for a housing market with no expectation of thermal performance. Insulation arrived later, retrofitted into spaces never designed to accommodate it, and the results vary enormously from street to street.
On survey we routinely find the same handful of problems: material compressed to a fraction of its depth by boards laid straight onto the joists, insulation packed hard into the eaves and sealing off the roof's only ventilation path, hatches left as bare uninsulated panels, and recessed downlighters buried under wool. None of these are exotic and all of them are fixable — but they need finding first.
Subdivision into flats is very common, so ownership of the roof space is worth establishing before work is booked, which is one more reason we measure rather than assume.

Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.

A/A+ fire rated and around 40mm thick. For Wallington properties where deepening the rafters is impractical, this is what makes the numbers work.

Mineral wool cross-laid to the 270mm depth current regulations recommend. For most Wallington homes this is the single highest-value thing you can do to the building.

Tongue-and-groove panels, screwed rather than nailed so they lift again if a cable needs reaching — raised clear of the insulation throughout.

The thing that turns a loft you avoid into one you use. Grab rails and a boarded landing area where the design allows.

One team, one survey, one sequence of work. The insulation depth sets the batten height, the batten height sets the ladder landing — which is why doing it piecemeal costs more.
Describe the property and what is bothering you about it, and we will recommend the right combination — or tell you that nothing needs doing.
Where we work
We are in and around Wallington most weeks, and the same teams cover Sutton and Croydon. Coverage across South London is continuous rather than patchy, so a postcode on the boundary is not a problem.

Questions & answers
Certainly. Doing the ladder in the same visit means the boarding is planned around where the ladder lands, which is considerably better than retrofitting one to a deck that was not designed for it.
There is no single figure, and anyone offering one for Wallington without seeing the loft is guessing. The largest swing factor is almost always whether the existing material can be topped over or has to be stripped out and disposed of. We survey free of charge and quote a fixed price afterwards.
A straightforward insulation job in a three-bedroom Wallington property is a half-day. Larger, cluttered or awkward-access lofts take longer, and stripping out failed material adds time — all of which is established at survey and reflected in the quote.
None of the work we do requires planning permission. If your Wallington property is listed or in a conservation area, that affects the roof covering and external alterations rather than insulation laid inside the roof space, though it is always worth mentioning at survey.
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.
270mm of mineral wool, cross-laid — the depth current building regulations guidance points to for a cold loft. Where a Wallington property has a room in the roof and depth is constrained, we use 40mm multifoil at rafter level instead.
