Floor Insulation in Stillorgan
Insulating suspended timber and solid ground floors to stop cold floors and draughts at skirting level. Covering Stillorgan Village, Mount Merrion, UCD and the surrounding area.
Floor Insulation for Stillorgan homes
Many of Stillorgan's post-war houses have suspended timber ground floors, which explains the cold feet many owners notice. Insulating between the joists and sealing the perimeter makes a clear difference. Where floors have already been replaced with concrete, insulation goes over the slab when the finish is renewed.
How homes in Stillorgan lose heat
Some of the earlier post-war houses here were built with solid or hollow-block walls rather than cavities, which a quick borescope check confirms. Typical ratings sit around D1 to E1, held back by walls, thin attic insulation and uninsulated floors. Detached homes have four exposed walls, so wall insulation has a large effect.
Typical housing: Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.
Planning: Little conservation constraint on the estates, so external insulation is usually exempted development.
How floor insulation works
Ground floors lose heat into the ground and, in older homes, let in a surprising amount of cold air. Period houses with suspended timber floors are often draughty because air moves freely through the ventilated void below and up through gaps between boards and at the skirting.

Floor Insulation in Stillorgan: questions
Do you carry out floor insulation in Stillorgan?
Yes. We cover Stillorgan and the surrounding Dublin area, including Stillorgan Village, Mount Merrion, UCD. Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.
Is planning permission an issue for floor insulation in Stillorgan?
Little conservation constraint on the estates, so external insulation is usually exempted development. We check the planning position for your specific house at the free survey, before any work is specified.
Is there a grant for floor insulation in Stillorgan?
SEAI grant-aids floor insulation at €3,500 when it is part of a home upgrade through an SEAI One Stop Shop. It is not available as an individual grant. 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.
Can you insulate a suspended timber floor without removing it?
In some homes the floor can be insulated from below through an accessible void, but most Dublin period floors need boards lifted. We assess access before recommending a method.
Will floor insulation stop draughts?
Yes. Much of the cold felt in period homes comes from air moving up through boards and at the skirting. Sealing those gaps is part of the job.
Is there a grant for floor insulation?
Floor insulation is grant-aided at €3,500 through the SEAI One Stop Shop route, not as an individual grant. We can advise whether that route suits your upgrade.
