Construction mastic for Oakley Green sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Put any product change through the designer first
- Record the products used in the O&M file
- Don’t force external sealing on a damp or frosty day
- Release areas for mastic once other trades have finished in them
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead so keep them off the joints.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.
How we handle construction mastic in Oakley Green
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. If you have inconsistent sealant finishes from plot to plot and internal caulk splitting as the building dries out, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Oakley Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Oakley Green, building work typically 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.
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’re clear about what is covered before work starts.

Why it’s worth doing now in Oakley Green
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification rather than at the snagging stage. Called in at the end, the same issues surface during handover. One visit to deal with every failing joint makes more sense than several trips to a place like Oakley Green. Send photos of each area and we will quote for the lot.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Different surfaces, different methods
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 work only when conditions suit.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.
Questions about Oakley Green
Is Oakley Green too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you take on a job at a hospital such as King Edward VII Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you work to our specification?
The specification decides the product, and we will raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.
Do you install fire-rated sealant as part of a package?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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, and each stage is agreed with your contact.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Oakley Green can form part of a wider programme.
Building and refurbishing in Oakley Green
Oakley Green lies roughly 25 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Oakley Green has several hotels close by, all within 2 miles. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
Extensions at sites like King Edward VII Hospital, 2.2 miles east of Oakley Green, usually sit beside working departments, and the mastic follows strict access rules. University estates such as Imperial College Silwood Park Campus, 4.8 miles south of Oakley Green, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Units on estates such as Bray Business Centre, 2 miles to the north-west of Oakley Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Oakley Green is about 1 mile west of Windsor, in Windsor and Maidenhead. Any commercial site in Oakley Green is covered. We work across 60 places in Windsor and Maidenhead. For work in that direction, see our Reading page (14 miles or so).
