Are replacement sliding doors right for your Dungiven home?
Most homeowners choosing replacement sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Does the old door in your Dungiven kitchen whistle in the wind or leave puddles on the sill? Worn seals and failed drainage are common reasons to replace rather than repair.
Before booking a survey for a Dungiven flat, check your lease or title deeds and speak to the managing agent, factor or other owners, because doors in flats may need consent that houses do not.
- 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.
- 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.
- 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.
Sunlight, glass and orientation in Dungiven
At the latitude of Dungiven, the midday sun climbs to about 59° in late June but only about 12° in late December, when daylight lasts around 7 h 11 min against 17 h 21 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.

Questions about replacement sliding doors in Dungiven
Do I need building approval for replacement sliding doors in Dungiven?
In Northern Ireland the Building Regulations (Northern Ireland) apply through district council building control; work there is by arrangement. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
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.
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.
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.
