Insulation Contractors in Galway

Galway's housing splits sharply. The city and its suburbs filled out between the 1970s and the early 2000s with hollow-block and cavity-block construction — Knocknacarra, Doughiska and Oranmore are largely this. West of the city, Connemara holds a great deal of older solid stone and rubble-filled wall, much of it rendered at some point in the last century.

Covering Galway city, Salthill, Knocknacarra, Oranmore, Barna, Moycullen, Tuam, Athenry, Loughrea, Ballinasloe and Connemara.

What houses in Galway are actually like

Galway's housing splits sharply. The city and its suburbs filled out between the 1970s and the early 2000s with hollow-block and cavity-block construction — Knocknacarra, Doughiska and Oranmore are largely this. West of the city, Connemara holds a great deal of older solid stone and rubble-filled wall, much of it rendered at some point in the last century.

The problem specific to this area

Galway sits in one of the most exposed wind-driven-rain zones in Europe. That matters more than most homeowners realise: it is the single reason a cavity fill that works perfectly in the midlands can be the wrong call here. Bonded-bead systems carry NSAI Agrément certification that restricts their use in severe exposure, and a cavity that gets wet transmits cold rather than stopping it.

Exposure zone. This is a severe wind-driven-rain exposure zone. It genuinely changes which systems are appropriate, and any contractor who does not raise it with you has not looked.

What we usually recommend in Galway

On exposed coastal and city-fringe properties we very often recommend external wall insulation over cavity fill, because it puts a continuous weatherproof layer outside the structure rather than filling a void that is doing a drainage job. Inland — Loughrea, Ballinasloe, Athenry — cavity fill is frequently the right and much cheaper answer.

A great many Galway city semis of that era sit at D1–E1 before work. Wall and attic together typically move them into the C band.

Common questions

Do you cover all of County Galway?+

Yes. We work across Galway city, Salthill, Knocknacarra, Oranmore, Barna, Moycullen, Tuam, Athenry, Loughrea, Ballinasloe and Connemara. If you are unsure whether your address is covered, send us your Eircode and we will confirm before anything else is discussed.

Which insulation is right for a house in Galway?+

It depends on how your walls are built, not on the county alone. This is a severe wind-driven-rain exposure zone. It genuinely changes which systems are appropriate, and any contractor who does not raise it with you has not looked. On exposed coastal and city-fringe properties we very often recommend external wall insulation over cavity fill, because it puts a continuous weatherproof layer outside the structure rather than filling a void that is doing a drainage job. Inland — Loughrea, Ballinasloe, Athenry — cavity fill is frequently the right and much cheaper answer.

How much does insulation cost in Galway?+

Cost depends on the wall area, the system and the condition of the existing fabric, so a figure quoted without seeing the house is guesswork. We charge €100 for a measured survey and refund it in full against your order, so the survey costs nothing if you proceed.

Can I claim an SEAI grant?+

If your home was built and occupied before 2011 you are likely eligible. Grant amounts vary by dwelling type — a detached house receives more than an apartment for the same measure. The current amounts by house type are set out on our SEAI grants page.

What BER improvement should I expect in Galway?+

A great many Galway city semis of that era sit at D1–E1 before work. Wall and attic together typically move them into the C band. A BER assessment after the work is what confirms the actual figure for your house.
