Airtightness Testing in Greystones
Blower-door testing that measures how much heat your home leaks through gaps, and shows exactly where. Covering Greystones harbour, South Beach, Charlesland and the surrounding area.
Airtightness Testing for Greystones homes
Greystones homes near the harbour face wind straight off the Irish Sea, and in older cottages and Victorian terraces that drives air through sashes, floors and chimneys. Mid-century homes in the centre leak at hatches and floors. Charlesland and other newer estates are generally tight but can have gaps around downlights and services. A blower-door test shows how much the coastal wind is costing each house type and what to seal.
How homes in Greystones lose heat
Harbour-side homes face wind and salt off the Irish Sea, with solid walls that need moisture-safe insulation and draught-proofing. Mid-century homes often have empty cavities. Charlesland and similar estates rate around B3 to C2 and mostly benefit from attic top-ups and airtightness checks.
Typical housing: Coastal cottages and Victorian terraces near the harbour, mid-century estate housing through the centre, and 1990s and 2000s estates such as Charlesland on the outskirts.
How airtightness testing works
An airtightness test pressurises or depressurises your home with a calibrated blower-door fan fitted into an external doorway. By measuring how much air the fan has to move to hold the pressure difference, we can put a number on how leaky the house is, expressed as air changes per hour or cubic metres per hour per square metre of envelope.
Airtightness Testing in Greystones: questions
Do you carry out airtightness testing in Greystones?
Yes. We cover Greystones and the surrounding Co. Wicklow area, including Greystones harbour, South Beach, Charlesland. Coastal cottages and Victorian terraces near the harbour, mid-century estate housing through the centre, and 1990s and 2000s estates such as Charlesland on the outskirts.
Is there a grant for airtightness testing in Greystones?
Airtightness work carries a €1,000 SEAI grant when it is part of a home upgrade through an SEAI One Stop Shop. We can advise whether that route suits your project. Grant amounts are set nationally by SEAI and change from time to time, so check seai.ie before applying. We confirm what your home is likely to qualify for during the survey.
What does an airtightness test involve?
A calibrated fan is fitted into an external door frame and used to pressurise or depressurise the house. The fan measures how much air is needed to hold the pressure, which gives the leakage rate. We then trace where the air is getting in with smoke and, where useful, a thermal camera.
Do I need to prepare my home?
Close external windows and doors, leave internal doors open, and make sure we can reach the attic hatch. Fires and stoves need to be out and cold. Allow two to three hours for a typical house.
Can a house be too airtight?
A house can be airtight without being stuffy, as long as ventilation is planned. Airtightness controls uncontrolled draughts; ventilation then supplies fresh air where and when it is needed. We advise on ventilation whenever a test shows the house is getting tighter.
Is an airtightness test needed for a heat pump?
Heat pumps work best in well-sealed, well-insulated homes, and many retrofit projects measure airtightness before and after the works. A test tells you whether draught-proofing is needed before a heat pump goes in.
