Draught-proofing in County Antrim

County Antrim properties get the same survey-first approach to draught-proofing: check, explain, price, then book. Draught-proofing seals the gaps that let warm air out and cold air in, around doors, windows, letterboxes, loft hatches and skirting boards, while leaving planned ventilation alone.

Draught-proofing across County Antrim

We cover 7 towns in County Antrim, including Belfast, Lisburn, Newtownabbey, Carrickfergus, Ballymena and more.

Where a County Antrim home also has empty cavity walls, we can survey those at the same time. We check ventilation as carefully as insulation in County Antrim homes, because both matter for keeping a house dry.

Building control in Northern Ireland

In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.

Funding in Northern Ireland

  • The Affordable Warmth Scheme, run with the NI Housing Executive, helps owner-occupiers and private tenants with a total gross household income under £23,000; cavity wall insulation is a priority measure where suitable.
  • The NI Sustainable Energy Programme funds energy efficiency schemes through participating providers.
  • ECO4 does not apply in Northern Ireland.

Ventilation still matters

Trickle vents, air bricks and extractor fans are there for a reason. We seal accidental gaps, not the ventilation your home needs to keep condensation down.

What is included

  • Door and window seals
  • Letterbox and keyhole covers
  • Loft hatch seals
