How we handle facade sealing in Dunsbury
Managing agents and owners in Dunsbury 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. Each job carries our 12-month guarantee. Site teams most often ask us about cold air coming in at window perimeters and old perimeter mastic that has dried out, across coping and flashing joints, window and door perimeters and stone and brick facade joints. Looking for mastic applicators who cover Dunsbury? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In the countryside around places like Dunsbury, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we’re called out for in Dunsbury
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
These are often picked up first by site or facilities staff:
- Failed sealant on precast panel joints
- Perimeter sealant that has split or peeled away
- Weathered facade joints that have lost their grip
- Water coming in around window frames
Historic houses such as Mottistone Manor, 1.2 miles east of Dunsbury, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Questions we’re asked in Dunsbury
Can being near the sea in Dunsbury affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Can you keep pace with our programme in Dunsbury?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Can you work on upper floors?
Access is planned with you before we quote. Let us know what access is in place or planned, and we will price the work around it.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Should we check old sealant for asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed. We don’t remove asbestos-containing materials.
Why act early in Dunsbury
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. One visit to deal with every failing joint makes more sense than several trips to a place like Dunsbury, rather than one at a time. Photos of every joint help us quote for the whole job.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why us?
- RAL and finish matching where the product range allows
- Constructionline member for supplier checks
- One number for every site we cover
- Standard and matched colours in many product ranges

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Render or concrete edges that have broken away
- Joints too narrow for the movement they take, which need redesign
- Work on the window or framing system itself
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.
Surfaces we seal

Contractors’ notes for Dunsbury
Dunsbury sits close to the coast, within about 1 mile. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Dunsbury sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
Sites around Dunsbury get mastic sealed to the drawings and the programme, nothing improvised.
