Before we insulate an attic, we check the full picture.

On this job, we spotted a few things that needed sorting first:

The ballcock was sitting too high and needed to be brought down properly.

The tank had swollen because the mains pipe wasn’t supported correctly, allowing the ballcock to finish too high and thus overfill it each time beyond the regular level.

The tank was dirty inside and needed a good clean.

The bathroom fan duct was venting into the tank area instead of outside, so that needed to be redirected through a roof vent.

We also recommended fitting a proper tank cover to help protect everything going
forward.

At Fitzsimons Insulations, we don’t just insulate attics — we look after them like
they’re our own.

Spot the issues. Fix them right. Get the job completed properly.

We’ve got your back.

A tidy job finished.
Raised flooring built on solid timber joists, so there’s no compression of the insulation underneath.
That means the attic stays usable for storage, and the insulation can actually perform the way it should.

A cracked tile spotted during an extension roof inspection yesterday.
The homeowner hadn’t noticed it, but remembered hearing a loud bang while work was happening next door last summer.
We returned this morning with a spare tile and replaced it with our compliments.
We also noticed a few other minor roof issues and recommended a trusted local roofing company to make everything right for the long term.
At Fitzsimons, we treat every home as if it were our own. If something doesn’t look right, we don’t ignore it — we let you know.
Since 1980.
That’s just how we do things.

Another year rolls around for our team member, Nicolae!
It’s great to have you with us, and we’re glad we could celebrate another birthday together today.
A special thank you to our co-founder, Christopher Fitzsimons, for stopping by early this morning to present a birthday gift and mark the occasion. It’s those personal touches that make us who we are.
Here’s to another great year ahead!

A customer had water spilling from the overflow pipe outside from time to time.
Turned out the small header tank was pressing on the walls of the main tank, forcing extra water in and lifting the water level.
We re‑framed it so the small tank is now fully self‑supported, with no pressure on the main tank and no more overflow issues.

Small detail, big difference.

Great to see the flexi hose running right out to the soffit outlet here. The outside cover had fallen off over time, so today we fitted a new one. A small job like this makes a big difference, helping stop warm, moist air getting into the attic or trapped in the eaves, where it can cause problems later.

Heat loves an easy escape route – and an uninsulated attic hatch is just that.

We’ve been sealing leaky attic hatches and insulating attics across Dublin & beyond since 1980, helping homes feel warmer for less.

Spot a chilly-looking hatch like this on your landing? That’s your cue to get it insulated and airtight.
