Construction mastic in Tunstall
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Joint design decisions that belong to the architect or engineer
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joints damaged after sign-off by following trades
If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.
What we seal
- Cladding and panel joints
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Floor and skirting junctions
- Sanitary and kitchen joints
Construction mastic in Tunstall
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Tunstall, send drawings and the specification through our quote form. We work on internal decorators’ caulk, sanitary and kitchen joints and window and door perimeters, and the failures we are asked to look at most are mastic snags holding up handover and cracks opening in caulked internal joints. For commercial sealant work in Tunstall, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Tunstall, building work usually 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.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself usually taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Jobs in and around smaller places like Tunstall are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We price from the drawings, specification and programme you send.
- 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.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Preparing the site
- Warn occupants and staff about the work
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
What the job involves on each surface
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Common questions from Tunstall clients
Can work at a site such as Canterbury Christ Church University fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is hospital work, at somewhere like Sittingbourne Memorial Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you seal external joints in wet or cold weather?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. External work is sequenced with some flexibility.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you install fire-rated sealant as part of a package?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Facades, frames and programmes in Tunstall
Tunstall is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Tunstall has a number of hotels close by, all within 2 miles. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Hotel extensions and refits, at places such as The Bull Hotel, 1.3 miles north-east of Tunstall, usually run between busy periods, so the sealing is squeezed into short windows. Projects at colleges like Sittingbourne College, 0.7 miles north of Tunstall, tend to run to term dates, so the mastic is planned tightly.
Tunstall is about 1 mile south-west of Sittingbourne, in Kent. Across the ME9 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places, from busy centres to rural villages. London is covered too, some 37 miles away.

Do you need construction mastic in Tunstall?
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
What tends to prompt an enquiry:
- Internal caulk splitting as the building dries out
- Frame perimeters left unsealed or poorly sealed
- Mastic snags holding up handover
- Frame gaps too wide for sealant alone
When units on a site such as Kent Science Park (to the south of Tunstall) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Is the sealant right for the movement and the substrate?
Maintenance after handover
For the best life from the joints:
- Ask for joint and product checks before the package is urgent
- Use the product the specification names
- Plan external elevations with the weather in mind
- Keep scrapers and abrasive pads off new beads
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault.
One unsealed frame can let water into finished internal areas. That usually means redoing finishes in a completed area. A check of every frame before decorators start is worth the time.
