Window and Door Installation in Ireland
Window and door installation in Ireland covers the supply and fitting of replacement windows, external doors, patio sliders, composite front doors and internal door sets in homes, apartments and small commercial units. The work usually begins with a site visit so the installer can measure each opening, check the wall type, and confirm what the existing frames are set into. That matters because Irish housing stock is mixed: solid block, cavity block, timber frame, and older cottages with uneven reveals all behave differently when an old frame comes out. A written quote normally follows the visit, setting out the window or door specification, glazing, ironmongery, fitting, making good, and removal of the old units. The customer's job is to describe what they want, gather quotes, compare the detail rather than the headline, and agree a start date. Posting a task on ShamFix costs nothing today.

What shapes the price of window and door installation
- The number of openings is the first driver.
- A single door replacement is a different job from a full house of windows, and pricing usually reflects the total count rather than one unit.
- Size and shape come next: standard casement sizes cost less to make and fit than large fixed panes, arched heads, bay windows or corner posts.
- Material and specification move the figure substantially, whether the frames are uPVC, aluminium, timber, or aluminium-clad timber, and whether the glazing is double or triple, with or without a warm-edge spacer, acoustic laminate or solar-control coating.
- Access is a real cost in Ireland: a first-floor window over a conservatory, a rear elevation reached only through a narrow side passage, or a town-centre terrace with no off-street parking all slow the work and may need a tower or a crane.
- Condition matters too.
- If the existing frames are sound and the reveals are square, fitting is quicker.
- If there is rot, damp, cracked render or a lintel that needs attention, that is extra labour and materials.
- Extras such as cills, trims, blinds, ventilation slots, trickle vents, and making good inside and out should appear as separate lines so you can see what you are paying for.
How long window and door installation takes
Most window and door installations are measured, ordered and fitted in stages rather than in one visit. The site survey and quote usually take a week or two to arrange, depending on the installer's diary and how far they travel. Once you accept a quote, the frames and glazing are made to measure, which commonly takes several weeks; timber and aluminium units can run longer than standard uPVC, and bespoke shapes or colours add time. Fitting itself is often quick relative to the waiting: a single door can be done in a day, while a full house of windows may take two to five days, longer if scaffolding is needed or if the reveals need repair. Weather affects external work, particularly in exposed coastal counties and during winter. Realistic start dates depend on the manufacturer's lead time and the installer's schedule, so ask for a written programme with the order date, the expected delivery week, and the fitting dates, and agree what happens if the units arrive late or damaged.
What to ask before you hire
- 01Ask for a written quote that lists each opening, the frame material, the glazing specification, the ironmongery, and whether removal and disposal of the old units is included.
- 02Ask whether the price includes making good internally and externally, and who is responsible for repainting or plastering around the new frames.
- 03Ask about insurance: a current public liability policy and, where employees are on site, employer's liability cover.
- 04Ask for the VAT position in writing, since domestic and commercial work can be treated differently and the invoice should show the rate applied.
- 05Ask who will be on site each day, whether the same crew finishes the job, and how long the work is expected to take.
- 06Ask which professional body they are a member of, and whether they hold a trade qualification or registration relevant to window and door fitting.
- 07Ask about the guarantee: how long it runs, whether it covers the frame, the glazing unit and the labour separately, and what happens if a unit fails or a door drops.
- 08Ask who tidies up at the end of each day and who removes packaging, old frames and glass.
- 09Finally, ask for the payment schedule and whether a deposit is required before materials are ordered.

Window and door installation questions people ask
How long does it take to replace a front door in Ireland?
A standard front door replacement is usually a one-day job once the new door is on site. The old door and frame come out in the morning, the opening is checked and prepared, and the new frame is fixed, shimmed and sealed. Composite and timber doors may take slightly longer if the threshold or sidelight needs work. Making good around the frame is often left for the following day.
Do I need planning permission to replace windows in an Irish home?
Replacing windows and doors like for like generally does not need planning permission, but changing the size, shape, colour or material of the front elevation can. Protected structures and homes in architectural conservation areas are treated differently and usually need consent. Check with your local authority planning office before ordering, especially for apartments, terraces and homes in a conservation area.
What is the difference between double and triple glazing for Irish weather?
Triple glazing adds a third pane and an extra cavity, which improves thermal performance and reduces outside noise. Double glazing is usually sufficient for most Irish homes and costs less. Triple units are heavier, so frames and hinges must be specified for the extra weight. Ask for the energy rating of the whole window, not just the glass.
Can windows be fitted in winter or in wet weather?
Yes, but wet and windy weather slows the work and can affect sealants and finishes. Fitters often cover the opening with a temporary membrane while a unit is out, and they may reschedule if conditions are unsafe. External sealing needs dry surfaces, so a dry spell is preferred. Ask how the installer plans to keep the house weathertight each day.
How should I compare quotes from different window installers?
Compare the specification line by line rather than the total. Check the frame material, glazing type, ironmongery, ventilation, removal and disposal, making good, and the guarantee. A cheaper quote may exclude scaffolding, old frame removal or internal repairs. Ask each installer to confirm what is included in writing so the quotes describe the same job.
What guarantee should I expect on new windows and doors?
Guarantees vary by product and supplier, and are usually split between the frame, the sealed glazing unit and the installation labour. Ask for the guarantee period for each element in writing, what it covers, and whether it is transferable if you sell the house. Keep the certificate, the invoice and any maintenance instructions, since some guarantees require periodic adjustment of hinges and seals.
