Period property? We know your roof.

Much of Winchester's housing is Victorian and Edwardian — beautiful, but often under-insulated, so the rooms below the roof bake in summer and lose heat in winter. We work with the quirks of older roofs every week.

  • Right material for your roofFoil for tight loft rooms, mineral wool for open lofts — honest advice, not a hard sell.
  • Care with awkward accessTight hatches, water tanks and old timbers handled cleanly and safely.
  • Damp & ventilation awareWe insulate in a way that protects against condensation, not one that traps it.

Reviews

What Winchester homeowners say

A few words from recent jobs across the capital.

“Booked a free assessment and had our loft done the same week. The upstairs bedrooms stay so much cooler in this heat now, and the team left everything spotless.”

S
Sarah M.St Cross, SO23

“Honest from the start — they recommended boarding plus topping up the wool rather than the pricier option. Really happy with the result.”

D
Daniel O.Walthamstow, E17

“We had squirrels in the loft. They sealed everything and re-insulated. Six months on, no more scratching at night.”

FAQs

Common questions

How much does loft insulation cost in Winchester?

Most loft jobs start from around £250 depending on loft size, access and the material you choose. Your free assessment gives you an exact, fixed price with no obligation.

How much could I save on my energy bills?

An uninsulated loft can lose around a quarter of your home's heat in winter and let it pour in through the roof in summer. Upgrading to the recommended 270mm depth typically saves a meaningful amount each year — we'll give you a realistic figure for your property.

Does loft insulation really help in summer?

Yes. In hot weather the roof heats up and that heat radiates down into the rooms below — which is why top-floor and loft-conversion bedrooms get so stuffy. A well-insulated loft slows that heat coming in, keeping upstairs noticeably cooler and easing the load on fans or air conditioning.

Do you cover my area?

We arrange work for homeowners right across Winchester and central Hampshire. Pop your postcode in the form and we'll confirm straight away.

Will it be messy or take long?

Most loft insulation jobs are finished in a single day, and we leave your home clean and tidy.

Is there any obligation after the quote?

None at all. The assessment and quote are free — you only go ahead if you're completely happy.
