Why choose replacement sliding doors in Tenby?
These are the points a surveyor will go through with you when you choose replacement sliding doors for a home in Tenby:
Does the old door in your Tenby kitchen whistle in the wind or leave puddles on the sill? Worn seals and failed drainage are common reasons to replace rather than repair.
If your Tenby 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.
- Because the opening stays the same size, a straight replacement avoids structural work, steel beams and a Building Regulations structural application.
- 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.
- 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.
Daylight in Tenby and what it means for your glass
Because Tenby sees long summer days (about 16 h 40 min) and short winter ones (about 7 h 48 min), the elevation your door faces makes a real difference. With the midday sun at about 15° 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 Tenby?
A surveyor visits your Tenby home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 4–6 weeks for aluminium and 2–4 weeks for uPVC after survey sign-off — and fitting usually takes 1 day for a straight two-panel swap; 1–2 days for larger doors. We also cover Pembroke Dock (16 km west) and Milford Haven (23 km west).
Do you need approval in Tenby?
In Wales, replacement doors are covered by the Building Regulations as applied in Wales, including the Welsh Part L energy requirements and safety glazing rules. Compliance is arranged through a competent person scheme installer or your council's Building Control, and the certificate is kept with your property records.
Choosing the specification
- uPVC replacement. A cost-conscious choice for a straightforward swap, available in white and foiled colours.
- Lower threshold. A reduced-height sill where floor and outside levels allow, with suitable drainage.
- Slimline upgrade. Narrow interlocks for the maximum glass area the existing opening allows.
Questions about replacement sliding doors in Tenby
How soon can you survey in Tenby?
Surveys in the SA70 district are booked at a time that suits you, and we offer survey dates 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.
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.
