Sliding door replacement in Coleraine: what to know
Before you settle on a door type, it helps to know what replacement sliding doors do well and what to check before you order.
Considering a wider door for your Coleraine home while you are replacing it? Weigh up the extra cost of structural work against the gain in glass before deciding.
Does the old door in your Coleraine kitchen whistle in the wind or leave puddles on the sill? Worn seals and failed drainage are common reasons to replace rather than repair.
- Removal and disposal of your old patio door is included in our guide prices, so there is no separate skip or tip run to organise.
- Most two-panel replacements are completed in a single day, so the house is secure again by the evening without the room being out of use for long.
- Slimmer modern frames often give a larger area of glass within the same opening, letting more daylight into the room than the old door did.
Sunlight, glass and orientation in Coleraine
Because Coleraine sees long summer days (about 17 h 24 min) and short winter ones (about 7 h 08 min), the elevation your door faces makes a real difference. With the midday sun at about 11° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

What happens when you order replacement sliding doors in Coleraine?
We plan the job around your home in Coleraine: survey first, then a written quote, then manufacture (typically 4–6 weeks for aluminium and 2–4 weeks for uPVC after survey sign-off). The fitting itself usually takes 1 day for a straight two-panel swap; 1–2 days for larger doors. If you are in Portstewart or Portrush, the same process and prices apply. Coleraine is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
Do you need approval in Coleraine?
Building control in Northern Ireland is run by district councils under the Building Regulations (Northern Ireland). We take on work in Northern Ireland by arrangement and confirm what approval your door needs before anything is ordered.
Specification choices for replacement sliding doors in Coleraine
- Slimline upgrade. Narrow interlocks for the maximum glass area the existing opening allows.
- Lower threshold. A reduced-height sill where floor and outside levels allow, with suitable drainage.
- Aluminium replacement. A thermally broken aluminium slider with slim frames and a durable powder-coat finish.
Questions about replacement sliding doors in Coleraine
How soon can you survey in Coleraine?
Survey dates in the BT52 district are arranged individually when we reply to your enquiry. After you approve the written quote, manufacture is typically 4–6 weeks for aluminium and 2–4 weeks for uPVC after survey sign-off.
Can I get a bigger door in the same opening?
You can usually get more glass in the same opening, because modern frames are slimmer, but the overall door size stays roughly the same as the old one. Making the door wider or taller means widening the opening, which is structural work with a steel beam, calculations and a Building Regulations application. Our new openings page covers that.
How long does it take to replace a sliding patio door?
Replacing a two-panel sliding patio door typically takes one day, from removing the old door to sealing and trimming the new one. Larger doors, three- or four-panel sets and doors needing extra making good typically take one to two days. Manufacture comes first, typically 4–6 weeks for aluminium or 2–4 weeks for uPVC after you sign off the surveyed specification.
What happens to my old patio door?
We remove your old patio door and take it away for disposal as part of the job, and that is included in our guide prices, so there is nothing for you to arrange. If you would rather keep the old door, for example for a shed or greenhouse project, tell us before the fitting day and we will leave it safely on site.
