How the job changes by surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we’ll tell you if the detail calls for something else. Record requirements are agreed with the quote.
Construction mastic for commercial buildings in Wimbledon
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you are dealing with internal caulk splitting as the building dries out and snag items on joints that need redoing before handover, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Wimbledon tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

How a job runs
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. All of Greater London is in the ULEZ, and kerbside space in Wimbledon can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- 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.
- 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.
Before we start on site
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected

FAQs: Wimbledon
Would you work within a site like St George's Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Nelson Trading Estate, close to Wimbledon?
Yes. We cover Wimbledon and the area around it, including industrial estates, business parks and retail parks such as Nelson Trading Estate. Photos and a short description are enough for a first look.
Do you do fire-rated sealing on new builds?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Rework caused by others damaging completed areas
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly.

Cost factors for mastic packages
These are the things that shape the price:
- How accessible the joints are
- Working within restricted access windows
- How much existing material needs removing
- Joint width, depth and condition
There’s no price list, since every building and every scope is different. Call for a quote.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- The asbestos register, for older buildings
- The site address and postcode
- Clear photos of the problem areas
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Facades, frames and programmes in Wimbledon
Site traffic in Wimbledon falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Wimbledon takes in a good number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Work at a hotel such as Justin James Hotel (less than half a mile south of Wimbledon) tends to be programmed around bookings, mastic included. For contractors on a campus like Kingston University Roehampton Vale Campus, 1.9 miles north-west of Wimbledon, facade and perimeter sealing has to fit around students and term dates. When units on a site such as Nelson Trading Estate (1.1 miles south-east of Wimbledon) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Wimbledon is about 7 miles south of City of Westminster, in Greater London. Our applicators travel to Wimbledon for work on mastic packages. Wimbledon is one of 764 places we cover in Greater London. Our London page has more on work in that area, about 7 miles away.
We take on mastic packages across the SW19, SW20, SW17 and SW18 postcode area. Buildings on High Street Mews, High Street and Church Road are within our area for mastic packages.

Just outside Wimbledon, we also work in Crooked Billet (1 mile west), Wimbledon Park (1 mile north), Wimbledon Chase (1 mile south), Copse Hill (1 mile south-west) and Merton Park (1 mile south-east).

Near you in Wimbledon
Locally, jobs take us to sites close to Willington School, Dog & Fox pub and Cannizaro Park and the streets around them. There’s a railway station in Wimbledon itself: Wimbledon station. Well-known places in the area include Atkinson Morley Hospital (1.2 miles west) and Wimbledon Museum (less than half a mile west). Green spaces nearby include Battersea Park Lake and Merton Park Green Walks.
Why it’s worth doing now in Wimbledon
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Looking after the joints
A few simple habits keep the new joints working:
- Put any product change through the designer first
- Release areas for mastic once other trades have finished in them
- Keep product details for future maintenance
- Ask cleaners to use soft cloths around fresh sealant
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover as agreed in the quote.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.
