Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Cost factors for mastic packages
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- The site’s rules and procedures
- Which sealant the job calls for
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Before you send an enquiry
However big the job, these details speed things up:
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
To get a fixed quote, call the office on 01277 525 020 or email the details over. Our quote form is another easy route.
How we handle construction mastic in Chaldon
Site managers want applicators who turn up with the right cards and paperwork. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you are dealing with early adhesion failures on new external joints and inconsistent sealant finishes from plot to plot, we can help. A specialist sealant contractor works differently from a general builder: in Chaldon, that means joint design, primers and backing rod as standard.
Sites around smaller places like Chaldon can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we’ll quote to suit.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Different surfaces, different methods
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we will confirm with the quote.
Signs you need construction mastic in Chaldon
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Common reasons buildings call us in:
- Missed perimeter joints on a new elevation
- Cracks opening in caulked internal joints
- New external sealant already peeling away
- A mastic package split between trades with no clear owner
When units on a site such as Church Walk Shopping Centre, 1.3 miles east of Chaldon, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether their applicators hold CSCS cards
- The terms of the workmanship guarantee
- What site paperwork they can supply
Your questions answered
Can you take on a job at a hospital such as North Downs Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is a smaller place like Chaldon outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
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.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Public liability insurance is in place.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
New build and refits around Chaldon
At about 15 miles from central London, Chaldon is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Chaldon included, is lower than in many parts of the UK. 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.
When a college such as Coulsdon Sixth Form College, 1.8 miles north of Chaldon, builds or refurbishes, the mastic package normally has to fit around students and staff. Extensions at sites like North Downs Hospital (to the east of Chaldon) typically sit beside working departments, and the mastic follows strict access rules.
Chaldon is about 1 mile south-west of Caterham, in Surrey. Across the CR3 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Surrey coverage takes in 379 places, large and small. Sites around London have their own page, about 15 miles away.
Business premises anywhere in CR3 are within our area for mastic packages. We cover commercial and managed buildings on Mount Avenue, Linden Drive and Marshall Close and the roads nearby.

Why it’s worth doing now in Chaldon
A quick bead over a damaged joint can get an area past inspection. 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. Converted and older buildings near places like Chaldon tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Doing it in-house
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
