Draught-proofing in Antrim

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 for Antrim properties

Antrim is among the towns we cover in County Antrim, alongside Ballymena, Newtownabbey and Belfast. It is roughly 16 miles north-west of Belfast.

In Antrim homes this is often done on the same visit as a cavity fill, which saves a second trip. We check ventilation as carefully as insulation in Antrim homes, because both matter for keeping a house dry.

For regulations, if cavity wall insulation follows in Antrim, inserting cavity wall insulation needs a building control application to the council before work starts.

Funding in Northern Ireland

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

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.
