About our construction mastic in Boyton Cross
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. If you’re dealing with bath and shower joints scraped during the final clean and failed sealant in an existing building being refurbished, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Boyton Cross, that means joint design, primers and backing rod as standard.
For a site near Boyton Cross, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Rework caused by others damaging completed areas
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Frames fitted out of tolerance
Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Boyton Cross: questions and answers
Is a smaller place like Boyton Cross outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is hospital work, at somewhere like Broomfield Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Can you fit around our programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Keep scrapers and abrasive pads off new beads
- Brief following trades on areas that have been sealed
- Share drawings and the specification as soon as possible
- Don’t force external sealing on a damp or frosty day
Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. Tell us what records you need and we’ll confirm with the quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors. Proper preparation, with the right silicone first time, keeps it off the defects list.
Sites and facades in and around Boyton Cross
Boyton Cross is about 27 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Boyton Cross 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, so the external programme keeps a little slack.
For a contractor working at a hospital such as Broomfield Hospital, which lies east of Boyton Cross, perimeter and facade sealing is planned around patients and deliveries. For contractors on a campus like Writtle University College Cow Watering Campus, which lies south-east of Boyton Cross, facade and perimeter sealing has to fit around students and term dates.

Surface by surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Common problems we fix in Boyton Cross
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
These are often picked up first by site or facilities staff:
- Frame gaps too wide for sealant alone
- Frame perimeters left unsealed or poorly sealed
- External joints sealed in damp or cold conditions that are now failing
- A mastic package split between trades with no clear owner
Projects at schools like Newlands Spring Primary School work to term dates, so mastic is programmed tightly.
Before you book anyone
- Will RAMS and insurance details be available?
- Do they follow the manufacturer’s priming guidance?
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
Cost factors for mastic packages
Before we quote, we look at:
- Location, for remote and island sites
- Any access equipment needed
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What we need to price the job
However big the job, these details speed things up:
- The asbestos register, for older buildings
- Any specification or named product
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
