Construction mastic near Sheerness
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What happens if it’s left?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. We’ll say so if a frame itself is the problem. For buildings in places like Sheerness, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What you get with us
- Joints cleaned back to sound surfaces
- Specification-led, product-correct work

Construction mastic in Sheerness
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. The enquiries we see most involve cracks opening in caulked internal joints and a long mastic snag list close to completion, on internal decorators’ caulk, floor and skirting junctions and window and door perimeters. For commercial sealant work in Sheerness, you deal with one contact from quote to sign-off, whether it’s one building or several.
In a smaller place such as Sheerness, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
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.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. If neighbouring businesses or buildings around Sheerness need work too, visits can be combined. Tell us your site hours and we will plan around them.
- 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.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Agree which areas must stay open
- Send your site hours and access windows
- Share the asbestos register for older buildings

Sheerness: questions and answers
Will you take on work at estates like Neats Court Retail Park, close to Sheerness?
Yes, sites like Neats Court Retail Park are within our area, along with the rest of Sheerness. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can work at a site such as Sheppey College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. 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: quantities, access, the product and any phasing. Call for a fixed quote.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photographs or drawings if you have them.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
What we’re called out for in Sheerness
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
Typical triggers for a call:
- Existing joints on a refurb that need cutting out and resealing
- New external sealant already peeling away
- Different trades sealing to different standards
- Snag items on joints that need redoing before handover
For contractors at a college like Sheppey College, less than half a mile north of Sheerness, perimeters and internal sealant are timed for the holidays.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
- What site paperwork they can supply
How the job changes by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Sites and facades in and around Sheerness
Sheerness lies within about 1 mile of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The South East is one of the drier parts of the UK. 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.
School extensions, at buildings such as Rose Street Primary School, typically run to the summer holidays, mastic included. New units and refits on sites such as Neats Court Retail Park (to the south of Sheerness) need their panel and perimeter joints sealed to the specification.
