Are replacement sliding doors right for your Shepton Mallet home?
A few practical points decide whether replacement sliding doors suit a particular room and opening:
If the existing opening in your Shepton Mallet home is sound and a sensible size, simply replacing the door gives the biggest improvement for the least disruption.
If your Shepton Mallet 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.
- 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.
- 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.
- Certification through a competent person scheme installer, or notification to Building Control, is arranged as part of the job and gives you a record for when you sell.
Planning glass for the light in Shepton Mallet
At the latitude of Shepton Mallet, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 53 min against 16 h 35 min in midsummer. A south-facing replacement sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

Timescales for replacement sliding doors in Shepton Mallet
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 4–6 weeks for aluminium and 2–4 weeks for uPVC after survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a straight two-panel swap; 1–2 days for larger doors for a door like this.
Do you need approval in Shepton Mallet?
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Options to consider for your replacement sliding door
- Slimline upgrade. Narrow interlocks for the maximum glass area the existing opening allows.
- 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.
Questions about replacement sliding doors in Shepton Mallet
Do you fit replacement sliding doors in Shepton Mallet?
Yes. We survey and fit replacement sliding doors in Shepton Mallet and across Somerset, including nearby Wells and Glastonbury. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
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.
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.
