Dry-Lining Insulation in Donegal
Dry lining bonds rigid insulation boards to the internal face of external walls, then skims with plasterboard to give a warm, ready-to-decorate surface. It is the internal alternative to external wall insulation for solid-wall homes and is widely used across older Irish properties where external works are not practical.
What the housing stock here is made of. A high proportion of stone and solid-block walls, including render-on-stone that was never designed to keep heat in.

Dry-Lining Insulation in Donegal: Common Questions
How Many Dry-Lining Insulation Contractors Are There in Donegal?
There are 74 SEAI-registered dry-lining insulation contractors based in Donegal. Every one is drawn from the official SEAI register, which is what keeps the work grant-eligible.
How Much Does Dry-Lining Insulation Cost in Donegal?
As indicative market guidance rather than a price, a three-bed semi runs €6,000 to €12,000 before any grant, with the SEAI grant currently €4,500 and most homeowners left with €1,500 to €7,500. Donegal being a rugged Atlantic coastal county in the northwest means access varies, and a quote should always come from a contractor who has seen the house.
Which Towns in Donegal Are Covered?
The contractors listed here work across Donegal, including Letterkenny, Buncrana, Ballybofey, Stranorlar, Bundoran, Donegal Town, Carndonagh and Ballyshannon. Most travel well beyond their registered address, so it is worth ringing a contractor based a county over rather than assuming they will not come.
Is My Donegal Home Suitable?
A high proportion of stone and solid-block walls, including render-on-stone that was never designed to keep heat in. Dry lining suits solid-wall homes where external insulation is not an option, whether because of planning constraints, a protected structure, a shared elevation on a terrace, or simply no room to build the wall outward.
How Is the SEAI Grant Paid in Donegal?
Through a One Stop Shop the grant comes off the price upfront. Apply yourself and you pay in full, then SEAI pays you back once the work is signed off. The grant for dry-lining insulation is €4,500, checked against SEAI on 31 July 2026. It works the same way everywhere in the country, so there is nothing specific to Donegal beyond choosing a contractor on the SEAI register, which every contractor on this page is.
