Looking to improve your energy efficiency and reduce heating costs? Our internal and external insulation services are the ideal solution for homeowners across Dublin and surrounding areas. Whether you’re dealing with draughty rooms, rising energy bills, or condensation issues, proper insulation is key to maintaining a warm, healthy home.

Internal insulation (also known as dry lining) involves fitting insulation boards on the inside of exterior walls.

External insulation wraps your home in a protective layer, finished with a durable, weather-resistant render.

testimonials

  • “We got external wall insulation done by this team last winter and the difference has been night and day. The house holds the heat so much better now, and our BER rating improved massively. The lads were sound – professional, tidy, and finished ahead of schedule. Highly recommended!”
    — Sean O’Sullivan
  • “Had internal insulation installed in our 1920s terraced home – I was worried about losing space, but they explained everything clearly and kept it minimal. The house feels warmer and quieter too. Very impressed with the workmanship and the finish!”
    — Gráinne Ní Bhraonáin
  • “Opted for cavity wall and attic insulation. The team showed up on time, were polite, and did a grand job. Took one star off only because they were delayed a day due to weather – not really their fault, to be fair. Would definitely use them again.”
    — Eoin McCabe
  • “Delighted with the service. We noticed an immediate drop in our heating bills after getting external insulation done. The house also looks much neater with the new render. Fair pricing too – great value for the quality of the work.”
    — Aoife Murph
  • “Top-class job. From the first call to the final inspection, everything was smooth. The house used to be freezing and draughty; now it’s warm all day with half the oil use. Can’t believe we didn’t do this sooner!”
    — Padraig Keane
  • “Brilliant service from start to finish. We had both attic and internal wall insulation done on our semi-D. The team was super knowledgeable and talked us through SEAI grant options too. The house is noticeably warmer, and the work was neat and professional. Would happily recommend them to anyone in the area!”
    — Niamh Gallagher
