What kind of home do you have?

Every kind of house has its own kind of loft. Pick yours to see what usually needs doing.

Why we start at the top of the house

Warm air rises through your home and gathers under the ceiling of the top floor. If the loft above has little or no insulation, that warmth passes straight into the roof space and out.

A deep, even layer on the loft floor keeps it in the rooms below. It’s usually the quickest, least disruptive thing you can do for a warmer home, and most lofts are done in a day.

  • Warmth from the rooms below
  • Insulation on the loft floor, between and over the joists
  • Air moving under the roof, so it stays dry

Does your home feel like this?

  • Bedrooms that stay coldUpstairs rooms sit right under the loft, so they feel thin insulation first.
  • A draught on the landingAn old loft hatch is often just a board in a hole, letting warm air straight up.
  • Joists you can seeIf the tops of the joists show in the loft, the insulation is too thin.
  • Heating on for longerIf the house never quite holds its warmth, the loft is the first place to look.

Questions homeowners ask

Why start with the loft?
Heat rises, so a poorly insulated loft lets warmth escape from the whole house. It’s usually the simplest and quickest place to make a difference.
Do you insulate walls and floors too?
We specialise in lofts: insulation, top-ups, replacing old insulation, boarding, ladders and the loft repairs that go with them.
How do I know if my loft needs more insulation?
If you can see the tops of the joists, it’s too thin. For mineral wool, around 270 mm is the depth commonly recommended.
Will it be messy?
We protect the landing, keep the dust in the loft and take the waste away with us.
How long does it take?
Most lofts are done in a day. Your quote says how long yours will take.
Is the work guaranteed?
Eligible installations come with a guarantee of up to 5 years. Your written quote says whether your job qualifies and what it covers.
