About our construction mastic in Highmoor
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 it helps to sequence elevations with some flexibility. Internal areas can typically carry on while the outside waits. If you have frame perimeters left unsealed or poorly sealed and sealant knocked or painted over by other trades, we can put it right, on floor and skirting junctions, brick and block movement joints and window and door perimeters alike. One point of contact handles commercial sealant work in Highmoor from the first photos to the final walk-round, whether it’s one building or several.
Sites around smaller places like Highmoor can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

What else we do in Highmoor
Facades, frames and programmes in Highmoor
There are several hotels within about 2 miles of Highmoor. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. At about 39 miles from central London, Highmoor is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.
Older buildings in the area around Highmoor, such as Greys Court (2 miles south-east of Highmoor), need care when sealed: the product has to suit soft or historic materials. Projects at schools like Stoke Row Church of England School work to term dates, so mastic is programmed tightly.

Your questions answered
Does your area include sites such as Vanalloys Business Park, near Highmoor?
Yes. Our area takes in Highmoor and its surroundings, with estates and business parks such as Vanalloys Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is Highmoor too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What does a mastic package usually include?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you fit around our programme?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready and we tell you if something stops an area being sealed.
Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference. Where an alternative is genuinely suitable, we will say so. For buildings around smaller places like Highmoor, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Common problems we fix in Highmoor
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
It’s worth sending us details if you spot any of the following:
- Existing joints on a refurb that need cutting out and resealing
- Inconsistent sealant finishes from plot to plot
- Window and door perimeters that won’t pass inspection
- Internal caulk splitting as the building dries out
Hotel extensions and refits, at places such as The White Hart Hotel, which lies north of Highmoor, typically run between busy periods, so the sealing is squeezed into short windows.
What your quote should include
- How they’ll work around occupants
- How they handle RAMS and site documents
- The named product and why it was chosen
- Will failed sealant be removed rather than covered?
Surface 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.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
