Internal doors for Irish homes: a plain guide to choosing well

1 August 2026 · The Home Upgrade Co.

New internal doors are one of the fastest ways to change how a whole house feels. Every room touches one, you see them a hundred times a day, and swapping tired doors for good ones lifts a hallway more than most bigger jobs. This guide covers the main types, where each works best, and what to check before you buy.

The main types of internal door

Panelled doors. The classic look, with two, four or six panels pressed or built into the face. They suit most Irish homes, from older red bricks to new builds, and they take paint well, so they are easy to refresh again years later.

Flush doors. A completely flat face, no panels. This is the door for clean modern interiors, and it pairs well with handleless kitchens and minimal skirting. The finish matters more on a flush door because there is nothing else to look at, so a good factory finish beats a site paint job.

Glazed and glass doors. A glazed door borrows light from the next room, which is why they work so well in Irish hallways and north facing rooms that never quite get bright. Clear glass keeps sight lines open between a kitchen and a living room. Frosted or reeded glass gives light without the view, which suits home offices and playrooms. A black framed glazed door has become the standout look of the last few years, and it earns its popularity: the dark frame makes both rooms feel more finished.

Bifold doors. Where a normal door would swing into furniture, a bifold folds back on itself and takes half the space. They are the practical answer for tight utility rooms, hot presses and wardrobe fronts, and a wide glazed bifold can open a kitchen to a dining space without a full structural job.

Solid core and hollow core. This is the difference you feel rather than see. A hollow core door is light and closes with a rattle. A solid core door feels substantial, deadens sound between rooms, and hangs better over time. If bedroom noise or a home office matters to you, solid core is worth it.

What suits older Irish houses

Older Dublin and Irish homes rarely have square openings. Frames settle, floors slope, and a standard size door off the shelf often needs real work to hang cleanly. Two things help. First, measure every opening separately, because the doors in one house are rarely all the same size. Second, decide whether you are keeping the existing frames and architraves. New doors in old frames can work well if the frames are sound, but if the frames are tired, replacing doors and frames together gives a far better finish for not much more disruption.

What to check before you buy

• Measure the height, width and thickness of each existing door, not just one.
• Check which way each door opens and which side the hinges sit. A door supplied the wrong hand is a returned door.
• Count the doors, then decide on one consistent style for the whole floor. Mixed door styles are the most common regret we see.
• Think about handles, hinges and latches at the same time. Matching ironmongery across every door is a small cost that makes the whole house feel considered.
• If a door separates a living space from a hallway, think about glazing to share the light.

Fitted properly, or not really fitted

A good door hung badly is worse than an old door. Gaps at the top, a latch that does not catch, a door that swings open on its own: all of it comes from the hanging, not the door. Fitting includes trimming each door to its own opening, packing hinges so the gaps run even, and setting the latch so it closes with a click rather than a shove. It is exact work, and it is the difference between doors you notice and doors that just feel right.

How it works with us

We design and fit internal doors across Dublin and Leinster, the same way we do kitchens: we call out, measure every opening, and you get a clear itemised quote with no obligation. You choose the doors, we handle the rest, and our own team does the fitting. One of our recent jobs, a black glazed internal door in a Dublin home, is in the gallery on our home page.
