How we handle construction mastic in Highleigh
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. We work on cladding and panel joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are early adhesion failures on new external joints and existing joints on a refurb that need cutting out and resealing. A specialist sealant contractor works differently from a general builder: on jobs in Highleigh, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as Highleigh 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
Why act early in Highleigh
A quick bead over a damaged joint can get an area past inspection, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. For buildings around smaller places like Highleigh, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Your questions answered
Do you take on work at healthcare sites like St Richard's Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Does the sea air around Highleigh change the choice of sealant?
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.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Sites and facades in and around Highleigh
Highleigh lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Highleigh lies roughly 59 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
School extensions, at buildings such as Sidlesham Primary School, normally run to the summer holidays, mastic included. New units and refits on sites such as Enborne Business Park (to the south-east of Highleigh) need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as St Richard's Hospital (4.8 miles north of Highleigh), perimeter and facade sealing is planned around patients and deliveries.
Highleigh is about 3 miles north of Selsey, in West Sussex. We cover commercial sites throughout Highleigh, whether it’s a single job or part of a planned programme.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
What affects the price in Highleigh
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- How much there is to seal
- Location, for remote and island sites
- The site’s rules and procedures
A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frame gaps too wide for sealant, which the installer needs to correct
- Designing joint widths or choosing the specification (that sits with the designer)
If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.
