Home Insulation Services
Insulating an entire house is rarely a single job — it’s a combination of attic, wall, floor and ventilation work, usually done in stages. For a typical 3-bed Dublin home, a comprehensive upgrade covering attic, walls and ventilation costs roughly €15,000–€30,000 before SEAI grants, which can reduce that significantly depending on your property type.
OSBER plans whole-house upgrades for homes across Dublin, Kildare, Meath and Wicklow — starting with a free assessment that tells you which area of your home is losing the most heat, so your budget goes where it makes the biggest difference first.
House insulation or home insulation — whatever you call it, the goal is the same: one plan covering attic, walls, floors and ventilation, sequenced so each measure supports the next. As Dublin home insulation specialists we survey first, insulate what pays back fastest, and handle the SEAI grants throughout.
Where Should You Start?
If you’re insulating room by room rather than all at once, order matters. In most cases:
Attic insulation first — it’s the cheapest area to insulate, often installed in a single day, and typically delivers the biggest early win since heat rises and escapes fastest through an uninsulated roof.
Wall insulation second — a bigger investment with a bigger long-term impact, especially worthwhile once the attic is already sorted and for homes with solid or poorly-insulated cavity walls.
Every home is different — a free assessment confirms the right order for yours. See our full guide on external wrap vs attic insulation: which to prioritise first.
What a Whole-House Upgrade Costs
For a typical 3-bed Dublin home, a comprehensive upgrade covering attic, walls and ventilation costs roughly €15,000–€30,000 before SEAI grants:
Attic insulation: €1,000–€3,500 (SEAI grant up to €1,500)
Internal wall insulation: €5,000–€25,000+ (SEAI grant up to €4,500)
External wall insulation: €12,000–€40,000+ (SEAI grant up to €8,000)
Floor insulation: €4,000–€20,000+
Ventilation: €2,500–€13,000+ depending on system type
Full detail on each is on the individual service pages — external wall insulation, attic & roof, floor insulation.

Benefits of House Insulation
A whole-house upgrade compounds these benefits rather than just adding them up — an insulated attic keeps warmth in, insulated walls stop it escaping sideways, and ventilation stops the moisture build-up that under-ventilated, over-insulated homes can get.
Energy Savings: attic insulation alone can cut heating costs by up to 30%.
Improved Comfort: fewer cold rooms, fewer draughts, more consistent temperatures floor to floor.
Better BER Rating: a full upgrade is what typically moves a home’s Building Energy Rating, not a single measure.
Increased Property Value: energy-efficient homes are increasingly what buyers screen for.
