Replacing a front door looks like a small job, and in many ways it is. But it is also the one opening in your house that has to be secure, weatherproof, level and good-looking all at once, and most problems we see with older doors come from how they were measured and fitted rather than from the door itself. Here is how a front door replacement works when it is done properly, so you know what to expect.
Step 1: the survey
A good replacement starts with a visit, not a catalogue. During a survey we look at:
- The existing frame and what it is fixed to. Is it timber, uPVC or aluminium, set in a block wall, a cavity wall or a timber-frame build?
- The condition of the surrounding wall, lintel and cill. Rot, damp or movement around the opening is much better found before the new door is ordered.
- Which way the door opens and what is behind it. A hallway radiator, a narrow porch or a step outside can all change the specification.
- Sidelights and fanlights. Many Galway homes have glazed panels beside or above the door. These can be replaced as one matching unit or kept separate.
This is also the time to talk about security, style and budget. Our guides to composite front doors and door colours and styles cover the choices in detail, and our security guide explains locking and insurance points.
Step 2: measuring and ordering
Made-to-measure doors are ordered to the size of the structural opening, with fitting allowances taken off, so accurate measurement matters. Width, height and squareness are checked in several places, because very few older openings are perfectly square.
At this stage you confirm:
- Door style, colour (inside and out) and glass pattern.
- Hardware: handle, letterbox, knocker, house number, spyhole and any security upgrades.
- Whether the door is a complete frame-and-door set or a door slab only. Replacing the whole frame is nearly always the better option, because a new door in a tired frame keeps the old frame's problems.
Made-to-order doors take time to produce, so allow a few weeks between order and fitting, and ask for a realistic date when you confirm the order.
Step 3: threshold and cill options
The threshold is the part people forget until it causes trouble. It needs to keep water out, but it also affects how easy it is to step over, push a buggy through or get a wheelchair in. Typical choices are:
- Standard raised threshold. The most weather-resistant option and the usual choice where wind-driven rain is a concern, which in the west of Ireland is often.
- Low or part-flush threshold. Easier for access and a good fit where accessibility matters, but it needs a well-detailed, sheltered opening or a porch.
- Cill and drainage detail. The way the cill sits and sheds water over the outer leaf of the wall matters as much as the frame itself.
If your home is exposed to coastal weather, mention that during the survey. Our guide to windows and doors in Connemara and coastal areas explains why exposure changes the specification.
Step 4: fitting day
On the day of the fit the old door is removed carefully, so surrounding plaster and masonry are disturbed as little as possible. The sequence is usually:
- Protect floors and set up a clean working area.
- Remove the old door and frame, and check the opening for damage.
- Fit the new frame level and plumb, packed and fixed through the frame into the structure.
- Insulate and seal the gap between frame and wall, inside and out.
- Hang the door, set the hinges and lock keeps, and adjust until it closes smoothly with even gasket compression.
- Fit the handles and cylinders, and test every key and lock.
A standard single door is normally a one-day job, though this can change with sidelights, an awkward opening or repairs to the surrounding wall. We will tell you in advance if we expect more time. Your home is secured before we leave.
Step 5: finishing and snagging
Once the door is in, a few items remain:
- Internal reveals. The inside edge of the opening may need plaster repair and decorating.
- External making good. Sealant, any render or pointing around the frame.
- Final checks. The door should close without slamming or dragging, the weather seals should touch evenly all round, and no daylight should show at the edges.
Keep the key cards, warranty paperwork and a note of the handing and hardware finish for future reference.
Looking after the new door
Composite and uPVC doors need very little care. Wipe the frame and seals with mild soapy water, lubricate hinges and lock mechanisms once or twice a year and check that the drainage slots stay clear. Our seasonal care guide has a simple routine.
