Why choose replacement sliding doors in Peacehaven?
A few practical points decide whether replacement sliding doors suit a particular room and opening:
If your Peacehaven 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.
If the existing opening in your Peacehaven home is sound and a sensible size, simply replacing the door gives the biggest improvement for the least disruption.
- 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.
- Because the opening stays the same size, a straight replacement avoids structural work, steel beams and a Building Regulations structural application.
- 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 Peacehaven and what it means for your glass
In Peacehaven the shortest day has roughly 7 h 57 min of daylight and the longest about 16 h 31 min. The noon sun sits near 16° above the horizon in winter and 63° 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.

Timescales for replacement sliding doors in Peacehaven
We plan the job around your home in Peacehaven: 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 Newhaven or Seaford, the same process and prices apply.
Do you need approval in Peacehaven?
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
- New internal cill or board. A fresh window board or reveal lining to finish the inside neatly.
- uPVC replacement. A cost-conscious choice for a straightforward swap, available in white and foiled colours.
- Slimline upgrade. Narrow interlocks for the maximum glass area the existing opening allows.
Questions about replacement sliding doors in Peacehaven
How soon can you survey in Peacehaven?
Surveys in the BN10 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.
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.
