One of the most common places a home loses heat is around the windows.
Plain plasterboard versus insulated plasterboard with airtightness tapes, sealed right into the window frame edge - it helps stop cold bridging, mould, and condensation before they start.
A small detail with a big impact.

Yesterday, while inspecting a customer’s attic ahead of an insulation upgrade,
we spotted a few things that shouldn’t simply be covered over
— possible woodworm activity, a possible old wasp nest and a pipe connection that needs attention.

It’s not just about rolling out insulation.
A proper attic inspection matters.

No insulation in the bay window ceiling 😳
We lifted the tiles and found… nothing. Just a completely bare ceiling.
If you suspect you have areas like this in your own home, give Fitzsimons Insulations a shout. We’d be happy to help where it’s possible to do so.

Your Attic Tank Might Need This First!
Before we insulate this attic water tank, there are a few things we recommend taking care of first.

💧 New insulated tank cover
🧼 Clean the inside of the tank — because, quite frankly, you don't want to be brushing your teeth with that water!

🔧 Adjust the ballcock so that it operates at the correct up-and-down angle. If it's left leaning to one side, the repeated movement over time can put unnecessary wear on the mechanism and cause it to fail sooner.

Once these items are addressed, we can properly insulate the tank and help protect it from heat loss and freezing temperatures.

🚨 Attic inspections can reveal more than just poor insulation.

This water tank looked ok at first glance, but a closer inspection showed:
💧 Dripping aged ballcock
🔧 Pipework that needs attention
🧼 A tank that's due for a proper clean

When we're in your attic installing insulation, we're also keeping an eye out for issues that could cost you money down the line.

That's the Fitzsimons difference – attic insulation with an extra pair of eyes.

This thermal camera clip shows warm patches above the light fittings in the upstairs corridor ceiling.
That’s because the insulation has moved away from each light, so the heat from outside sunshine and the warm summer air is heating the ceiling from above. Even with LED lights, these gaps can still cause problems. In winter, they will show up as cold spots if they’re not fixed. We’ll fit proper covers around the lights and top up the insulation to make the ceiling more efficient and help keep the home warmer.

Another attic, another one insulated properly. We also spotted a worn ballcock valve, replaced it with approval, and left the homeowner with one less thing to worry about.

Happy birthday, Sorin — have a brilliant day and a great weekend ahead. For the weekend that’s in it!
