Why choose replacement sliding doors in Newtownards?
Most homeowners choosing replacement sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Considering a wider door for your Newtownards home while you are replacing it? Weigh up the extra cost of structural work against the gain in glass before deciding.
If your Newtownards home still has its original sliding patio door, look at the glass beads: if they are on the outside, a replacement will close off that weakness.
- Multipoint locks, anti-lift devices and internally beaded glass close the security gaps that older patio doors commonly have, such as panels that can be lifted out.
- 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.
Light and sun in Newtownards
In Newtownards the shortest day has roughly 7 h 15 min of daylight and the longest about 17 h 17 min. The noon sun sits near 12° above the horizon in winter and 59° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

How fitting works in Newtownards

Questions about replacement sliding doors in Newtownards
How soon can you survey in Newtownards?
Survey dates in the BT23 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.
Is the survey free for a replacement door?
Yes, the survey for a replacement sliding door is free. We measure the opening, check its condition and the support above it, look at floor and outside levels, and talk through frame, glass and colour options. You then receive a written quote with the fixed price, and nothing is ordered until you confirm the surveyed specification in writing.
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.
What if there is no proper lintel above my old door?
Occasionally an old door frame turns out to be carrying some load because the support above the opening is inadequate or missing. We check the head of the opening at survey and again when the old frame comes out. If extra support is needed, we explain why, what it involves and what it costs before any further work goes ahead.
