Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Put any product change through the designer first
- Brief following trades on areas that have been sealed
- Keep product details for future maintenance
- Check frame gaps are within the sealant’s range before sealing
After we have sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.
Construction mastic in Highbrook, done properly
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Highbrook. We work on sanitary and kitchen joints, brick and block movement joints and internal decorators’ caulk, and the failures we’re asked to look at most are window and door perimeters that won’t pass inspection and mastic snags holding up handover. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Highbrook, preparation and product choice get the time they need.
Around smaller places like Highbrook, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What else we do in Highbrook
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Highbrook can sit alongside others in a wider programme across West Sussex.
When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Joints damaged after sign-off by following trades
- Frames fitted out of tolerance
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
Joints and surfaces we work on
- Sanitary and kitchen joints
- Cladding and panel joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Window and door perimeters
- Brick and block movement joints
Common problems we fix in Highbrook
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.
Things that typically lead to an enquiry:
- Frame gaps too wide for sealant alone
- Existing joints on a refurb that need cutting out and resealing
- A long mastic snag list close to completion
- Caulk cracking where joints are moving more than expected
School extensions, at buildings such as St Peter's CofE Primary School, usually run to the summer holidays, mastic included.
What to look for in a quote
- Will RAMS and insurance details be available?
- Their approach to joint depth and backing
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
Building and refurbishing in Highbrook
Highbrook sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Highbrook is about 31 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
Older buildings in the area around Highbrook, such as Priest House (1.5 miles north of Highbrook), need care when sealed: the product has to suit soft or historic materials. On a healthcare site such as Princess Royal Hospital (4.6 miles south of Highbrook), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Highbrook is about 4 miles north-east of Haywards Heath, in West Sussex. If you’re looking for construction mastic in Highbrook, we can help. We work across 373 places in West Sussex. For work in that direction, see our Brighton page.
