About our construction mastic in Dragons Green
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers, sealing plot by plot or floor by floor as areas are released. Site teams most often ask us about missed perimeter joints on a new elevation and inconsistent sealant finishes from plot to plot, across sanitary and kitchen joints, window and door perimeters and cladding and panel joints. A specialist sealant contractor works differently from a general builder: in Dragons Green, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Dragons Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Construction mastic in Dragons Green: the local picture
Dragons Green is about 37 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Dragons Green sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
New units and refits on sites such as Pondtail Farm (Business Park) (1.3 miles east of Dragons Green) need their panel and perimeter joints sealed to the specification. Projects at schools like Shipley CofE Primary School work to term dates, so mastic is programmed tightly.
Dragons Green is about 5 miles south-west of Horsham, in West Sussex. We cover commercial sites throughout Dragons Green. Dragons Green is one of 373 places we cover in West Sussex. For work in that direction, see our Brighton page.

What sets the cost
These are the things that shape the price:
- Access and working height
- The site’s rules and procedures
- The total length or number of joints
- Whether old sealant has to be cut out first
Pricing mastic packages depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Specification clauses that apply
- Anything awkward about access or site hours
- Any dates the work must fit around
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
Your questions answered
Can you work at a site such as Pondtail Farm (Business Park), by Dragons Green?
Yes, sites like Pondtail Farm (Business Park) are within our area, along with the rest of Dragons Green. A few photographs and the unit address let us price the work.
Is Dragons Green off your patch?
No. Places such as Dragons Green are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can fire-rated sealing at service penetrations be included?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. Fire-stopping design and sign-off sit with the designer and building control.
Can you work to our specification?
The specification decides the product and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What does a mastic package typically include?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Common problems we fix in Dragons Green
Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Common reasons buildings call us in:
- Perimeter gaps outside the sealant’s range
- A long mastic snag list close to completion
- Failed sealant in an existing building being refurbished
- Different trades sealing to different standards
Hospital estates such as Horsham Hospital (5.4 miles north-east of Dragons Green) 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.
Before you book anyone
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
What happens if it’s left?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. Older rural buildings around Dragons Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Why appoint us
- Specification-led, product-correct work
- Health and safety: CHAS accredited
- A range of standard colours, depending on the product
- Old sealant cut out, never sealed over

When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Frames fitted out of tolerance
- Deciding which fire-stopping product a penetration needs
- Joints damaged after sign-off by following trades
