Do I need planning permission for a Velux window in Dublin?

In most cases, fitting a Velux window to the rear of your house does not require planning permission, provided it doesn't change the shape of the roof. However, windows at the front may have different rules. We can advise you based on your specific Dublin City or County Council guidelines.

How long does a typical installation take?

For a standard roof, a single Velux window installation usually takes one day to get weather-tight and structurally sound. Interior finishing work may take a little longer depending on your requirements.

Are Velux windows energy efficient?

Yes. Modern Velux windows feature double or triple glazing with Low-E coatings, designed to trap heat inside during the winter. This is one of the most effective ways to improve the BER (Building Energy Rating) of your attic space.

What happens if it rains during the installation?

Being a Dublin-based company, we are used to the rain! We monitor the forecast closely and use professional-grade covers to ensure your home stays 100% dry while the window is being fitted.

Our Velux Services

New Roof Window Installations

Whether you’re converting an attic or simply want more light in a dark hallway, we handle the full installation. This includes the structural timber work, exterior flashing, and internal casing to ensure your new window looks like it was always part of the house.

Velux Replacements & Upgrades

If your old roof window is drafty, leaking, or has a "foggy" pane, it’s time for an upgrade. Modern Velux windows offer significantly better thermal insulation and noise reduction, keeping your Dublin home warmer in the winter and quieter year-round.

Sun Tunnels for Dark Spaces

For bathrooms, hallways, or walk-in wardrobes where a standard window isn't possible, we install Velux Sun Tunnels. These "light pipes" direct natural sunlight from your roof into your rooms, instantly brightening even the darkest corners of your home.

Solar & Electric Smart Windows

Upgrade your home with Velux Integra® solar or electric windows. These are perfect for out-of-reach ceilings and can be programmed to close automatically if it starts to rain—an essential feature for the Irish climate!

I couldn’t be happier with the work carried out on my roof. The tiles and felt were replaced, and from start to finish the service was absolutely top class.
