Construction mastic for commercial buildings in Sandwich
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. If you have cracks opening in caulked internal joints and inconsistent sealant finishes from plot to plot, we can help, on window and door perimeters, cladding and panel joints and floor and skirting junctions alike. Whoever orders the work in Sandwich, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Building work in places the size of Sandwich is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Every job we finish is backed by a 12-month workmanship guarantee, in Sandwich as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Working within restricted access windows
- Backing rod, priming and other preparation
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
Pricing mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Your programme or deadline
- The asbestos register, for older buildings
- The type of building and who uses it
- The site address and postcode
To get a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. Our quote form is another easy route.
Surface by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies and work only when conditions suit.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Record requirements are agreed with the quote.
Construction mastic around Sandwich: what changes locally
Sandwich sits close to the coast, within about 3 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. At about 64 miles from central London, Sandwich is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
School extensions, at buildings such as Sandwich Infant School, normally run to the summer holidays, mastic included. Hospital estates such as Ramsgate General Hospital, 5 miles north-east of Sandwich, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Sandwich is about 5 miles north-west of Deal, in Kent. Any commercial site in Sandwich is covered, for single jobs and planned programmes alike. Our Kent coverage takes in 931 places, from busy centres to rural villages. There’s a separate page for London, roughly 64 miles from Sandwich.

What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Approving fire stopping as compliant
- Designing joint widths or choosing the specification (that sits with the designer)
- Oversized gaps that need packing or adjustment by others
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we will tell you honestly.
Joints and surfaces we work on
- Window and door perimeters
- Floor and skirting junctions
- Brick and block movement joints
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. What matters most for a job in Sandwich is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance
- Make sure the joints can be reached

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What we are called out for in Sandwich
On construction sites, joints typically fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
Clients typically get in touch after noticing one or more of the following:
- New external sealant already peeling away
- Sealant knocked or painted over by other trades
- Different trades sealing to different standards
- Snag items on joints that need redoing before handover
For a contractor at a hotel such as The Fleur De Lys Hotel, less than half a mile to the north of Sandwich, the mastic often has to be finished before a reopening date.
What your quote should include
- How joint depth will be controlled
- How they handle RAMS and site documents
- How the existing material will be dealt with
- How the joint faces will be prepared and primed
Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Keep scrapers and abrasive pads off new beads
- Release areas for mastic once other trades have finished in them
- Ask for joint and product checks before the package is urgent
- Protect sealed areas from following trades
Any damage after we have finished should go on the snag list right away. We can return to clear snags before handover as agreed in the quote.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short, and avoids a rush.

Common questions from Sandwich clients
Is Sandwich too far out for you?
Not at all. Sandwich is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Ramsgate General Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do you do fire-rated sealing on new builds?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
Can you work to our specification?
The specified product is what goes in. Any suggested alternative is put to you before anything changes.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
