Keeping Dublin Homes Warm for 20 Years

About Us

Building a Brighter Future, Together

WarmSeal was born from a long line of plasterers. Ed Claxton’s grandad and dad before him laid the groundwork. Since 2007, we've grown from traditional plastering into full insulation systems, with a standout focus on external insulation since 2011. We’ve trained hard, earned top qualifications, including a distinction in Thermal Insulation Retrofit and proudly served on national projects like DIY SOS.

Our Missions :

What sets us apart? No subbing out, no rotating crews. When you choose WarmSeal, you deal directly with Ed and his team. 

We’re based in Balbriggan and work across Dublin and Meath, bringing expert knowledge, clean finishes, and a genuine care for your home. 

Our values are simple: family, high quality, and passing on what we know to the next generation.
