Sliding door replacement in Fareham: 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.
If the existing opening in your Fareham home is sound and a sensible size, simply replacing the door gives the biggest improvement for the least disruption.
Considering a wider door for your Fareham home while you are replacing it? Weigh up the extra cost of structural work against the gain in glass before deciding.
- 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.
- 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.
Light and sun in Fareham
At the latitude of Fareham, the midday sun climbs to about 63° in late June but only about 16° in late December, when daylight lasts around 7 h 56 min against 16 h 31 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 Fareham
A surveyor visits your Fareham 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 Gosport (7 km south-east) and Portsmouth (9 km south-east).
Do you need approval in Fareham?
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Finishes and extras for replacement sliding doors
- New internal cill or board. A fresh window board or reveal lining to finish the inside neatly.
- Aluminium replacement. A thermally broken aluminium slider with slim frames and a durable powder-coat finish.
- Upgraded glass. Triple, laminated, solar-control or obscure glass to suit the elevation.
Questions about replacement sliding doors in Fareham
Do I need building approval for replacement sliding doors in Fareham?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
Will the new door have a lower threshold?
A lower threshold may be possible on a replacement, depending on the floor level inside, the height of the patio or ground outside and how the opening was built. Low thresholds are typically 15–25 mm. A flush threshold needs a drainage channel outside so rain cannot run in. We check levels at survey and tell you what is realistic.
Do I need planning permission to replace a sliding door?
Replacing doors on a house is usually permitted development, so no planning application is needed, as long as the new doors are similar in appearance to the existing ones. Flats, listed buildings and properties covered by an Article 4 direction may need consent. Our planning guide explains more.
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.
