Facade sealing in Duncton, done properly
Managing agents and owners in Duncton ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. We work on coping and flashing joints, shopfront frames and window and door perimeters, and the usual reasons a site gets in touch are hard, chalky sealant that no longer flexes and staining on stone next to old sealant. Whoever orders the work in Duncton, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Conversions of older rural buildings near smaller places such as Duncton bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
A 12-month guarantee applies to all our work in West Sussex. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we’ll come back to it.

Advice
Facade sealing around Duncton: how the place shapes the job
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Central London is about 45 miles from Duncton. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Hospital estates such as Midhurst Community Hospital (to the north-west of Duncton) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Older buildings in the area around Duncton, such as Bignor Roman Villa (2.4 miles south-east of Duncton), need care when sealed: the product has to suit soft or historic materials. School extensions, at buildings such as Duncton CofE Junior School, normally run to the summer holidays, mastic included.
Duncton is about 10 miles north-east of Chichester, in West Sussex.

Duncton: questions and answers
Is Duncton too far out for you?
No. Places such as Duncton are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Will you fit the mastic around our build programme in Duncton?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can ring 01277 525 020 or send details through our quote form to arrange a visit. Many frame leaks are sealant failures, though not all.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you use silicone for external joints?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, depending on the substrate and the specification.
After the work
A few simple habits keep the new joints working:
- Plan facade sealing alongside redecoration
- Keep sills, gutters and drainage paths clear
- Never let anyone seal over old sealant
- Note when each elevation was last resealed
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

What else we do in Duncton
What sets the cost
The price varies from site to site. It mainly depends on:
- How accessible the joints are
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- Backing rod, priming and other preparation
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- Whether an asbestos survey exists
- The postcode of the building
- Any specification or named product
- Anything awkward about access or site hours
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email the details over.
Surface by surface
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
