Is a replacement sliding door a good fit for your home in Sittingbourne?
Most homeowners choosing replacement sliding doors want the same things: more light, a clear view and a door that is easy to live with.
If your Sittingbourne 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.
Does the old door in your Sittingbourne kitchen whistle in the wind or leave puddles on the sill? Worn seals and failed drainage are common reasons to replace rather than repair.
- 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.
- 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.
- 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.
How much sun will a door in Sittingbourne get?
Daylight in Sittingbourne runs from about 7 h 51 min in December to 16 h 37 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.
What should you budget for replacement sliding doors in Sittingbourne?
Guide prices are the same across Kent: the fitted price depends on the size, system and specification, not your postcode. These figures are for a standard 2.1 m high door, fitted, including VAT and removal of an old door of similar size.

|---|---|---|
| 3.6 m | 3 panels | £5,595–£6,895 |

What happens when you order replacement sliding doors in Sittingbourne?
We plan the job around your home in Sittingbourne: 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 Faversham or Gillingham, the same process and prices apply.
Do you need approval in Sittingbourne?
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.
Choosing the specification
- 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.
- Slimline upgrade. Narrow interlocks for the maximum glass area the existing opening allows.
Questions about replacement sliding doors in Sittingbourne
Can you match other doors and windows in my Sittingbourne home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
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.
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.
