Construction mastic for Roke sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Construction mastic in Roke, done properly
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. If you are dealing with early adhesion failures on new external joints and a long mastic snag list close to completion, we can help, on internal decorators’ caulk, window and door perimeters and floor and skirting junctions alike. A single leaking joint is often how a building in Roke first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites around smaller places like Roke can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Rural sites near Roke may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- Drawings, the sealant specification and your programme come to us for pricing.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints

What sets the cost
These are the things that shape the price:
- Which sealant the job calls for
- Removal of failed or old sealant
- Travel to remote or island sites
- Quantities, in metres or numbers
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Specification clauses that apply
- The asbestos register, for older buildings
- Where the site is, with the postcode
- 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. Where a site visit makes more sense, we’ll arrange one.
Why act early in Roke
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. Around Roke, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Why appoint us
- Fixed quotes based on photographs, drawings or a visit
- Colour agreed before work starts
- Products installed to the manufacturer’s instructions
- Standard and matched colours in many product ranges

What the job involves on each surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
Internal decorators’ caulk
Caulk is easy to apply badly. Done properly, it saves decorators time and gives a clean line.
Sites and facades in and around Roke
At about 44 miles from central London, Roke is within reach of the capital. 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. Roke is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
For a contractor at a hotel such as The White Hart Hotel, 1.2 miles south-west of Roke, the mastic often has to be finished before a reopening date. When units on a site such as Monument Business Park, 2.8 miles north-east of Roke, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Do you need construction mastic in Roke?
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
Clients usually get in touch after noticing something like this:
- Mastic snags holding up handover
- Sealant knocked or painted over by other trades
- Different trades sealing to different standards
- Missed perimeter joints on a new elevation
Historic houses such as Brightwell Manor (to the south-west of Roke) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Questions to ask before you book

Your questions answered
Is Roke too small for you to travel to?
Not at all. Roke is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our programme on a site in or near Roke?
Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you seal on top of existing 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 you clear a mastic snag list before handover?
Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Damage to finishes by other trades after we’ve sealed
- Frame gaps too wide for sealant, which the installer needs to correct
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
