About our construction mastic in Dummer
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. If you have caulk cracking where joints are moving more than expected and old sealant on a refurbishment that needs stripping before new work, we can put it right, on sanitary and kitchen joints, brick and block movement joints and internal decorators’ caulk alike. A specialist sealant contractor works differently from a general builder: on jobs in Dummer, preparation and product choice get the time they need.
Sites around smaller places like Dummer 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common questions from Dummer clients
Is hospital work, at somewhere like Park Prewett Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Dummer too small for you to travel to?
No. Places such as Dummer are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you work plot by plot or floor by floor?
We work to your programme. Share the release dates and we will match our work to them, sealing as areas become ready.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Do you need construction mastic in Dummer?
On construction sites, joints usually fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
These are often picked up first by site or facilities staff:
- New external sealant already peeling away
- A long mastic snag list close to completion
- Oversized or tapered gaps around new frames
- Window and door perimeters that won’t pass inspection
New wings at hospitals like Park Prewett Hospital (5 miles north of Dummer) bring long runs of window and panel joints to seal.
What your quote should include
- The terms of the workmanship guarantee
- The named product and why it was chosen
- Health and safety accreditation such as CHAS
- Their public liability cover
How the quote is worked out
To price the job, we consider:
- Working within restricted access windows
- Distance, for remote addresses
- Site requirements such as inductions and permits
- The product specified
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- When you need the work done
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
What else we do in Dummer
When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:
- Frames fitted out of tolerance
- Deciding which fire-stopping product a penetration needs
- Faulty frames rather than failed sealant
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we will give you a straight answer.
Where we work in Dummer

Why act early in Dummer
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. Around Dummer, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
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.
Why appoint us
- Public liability insurance in place
- Commercial sealant work since 2005
- Matching to RAL references, product permitting
- Colour agreed before work starts

Advice
Contractors’ notes for Dummer
Dummer 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 we time external mastic for dry faces and agree it with the site team. At about 50 miles from central London, Dummer is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
For contractors building in or near Dummer, we seal to the drawings, the specification and the programme.

Different surfaces, different methods
Window and door perimeters
Gaps around frames have to be within the sealant’s range. We check them during the first walk-round and flag any that need packing or adjusting.
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.
