Why choose replacement sliding doors in Havant?
A few practical points decide whether replacement sliding doors suit a particular room and opening:
If your Havant 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 Havant kitchen whistle in the wind or leave puddles on the sill? Worn seals and failed drainage are common reasons to replace rather than repair.
- 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.
- New rollers and a precision track make a heavy door glide with a light push, where an old door may need both hands and a firm shove to open.
- 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.
How much sun will a door in Havant get?
In Havant the shortest day has roughly 7 h 56 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.

From survey to fitted door in Havant
We plan the job around your home in Havant: 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 Emsworth or Waterlooville, the same process and prices apply.
Do you need approval in Havant?
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.
Finishes and extras for replacement sliding doors
- New internal cill or board. A fresh window board or reveal lining to finish the inside neatly.
- Upgraded glass. Triple, laminated, solar-control or obscure glass to suit the elevation.
- uPVC replacement. A cost-conscious choice for a straightforward swap, available in white and foiled colours.
Questions about replacement sliding doors in Havant
Do you fit replacement sliding doors in Havant?
Yes. We survey and fit replacement sliding doors in Havant and across Hampshire, including nearby Emsworth and Waterlooville. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
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.
