What to know about Air sealing
Air sealing is the job of making the heated envelope of a house continuous, so that outside air has to come in where you decided rather than wherever the building happens to leak. It overlaps with draught-proofing, which is about the gaps you can feel around doors, windows and letter plates, but it is a larger idea: most of the air moving through a British house never passes anything you would call a draught. It goes through the loft hatch, the gaps where pipes and cables cross the ceiling, the perimeter of a suspended floor, the back of a dry lining and the void behind a boxed-in soil stack.

How to choose insulation contractors in Folkestone
- Choose a contractor who talks about air sealing and ventilation, not only adding more insulation.
- Ask them to check the attic or walls for moisture, mould, old wiring or insulation that may contain asbestos before starting.
- Get a written quote that states the type of insulation, the areas covered and the target insulation level.
- For spray foam, ask about their training, curing time and when it's safe to be back in the home.
- Consider an energy audit before and after the work to see where heat is being lost.
Questions to ask insulation contractors before you hire
- What type of insulation do you recommend for this area, and why?
- Will you seal air leaks before insulating?
- How will you keep the attic properly ventilated?
- What will you do if you find old insulation that may contain asbestos, mould or old wiring?
- For spray foam, how long do we need to stay out of the house?
- Does this work need a permit or an inspection?
Air sealing permits in England
Some air sealing work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
Licensing in England
Consumer protection
Getting approval matters when you come to sell. GOV.UK warns that without building regulations approval you will not have the certificates of compliance you may need when you want to sell your home, so keep the completion paperwork or the installer's self-certification with your deeds.

Insulation Contractors guide
Insulating a British home usually means one of a small number of jobs: loft insulation, cavity wall insulation, solid wall insulation fitted inside or outside, underfloor insulation, and insulating a room in the roof.

Loft Insulation guide
Attic insulation is loft insulation in Britain, and in most houses it means a cold loft: insulation laid at ceiling level, with the roof space above it left cold and ventilated.

Basement Insulation guide
Insulating below ground is a different job from insulating the same wall two metres higher up, and treating them as the same thing is how British basements get ruined.
