Construction mastic near Emmbrook
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Construction mastic in Emmbrook
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve failed sealant in an existing building being refurbished and mastic snags holding up handover, across brick and block movement joints, cladding and panel joints and floor and skirting junctions. Searching for sealant specialists in Emmbrook? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around places like Emmbrook, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Common questions from Emmbrook clients
Does your area include sites such as Station Industrial Estate, near Emmbrook?
Yes. Estates, retail parks and business parks around Emmbrook, Station Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Emmbrook outside your area?
Not at all. Emmbrook is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work, so internal areas are often done on those days.
What does a mastic package typically include?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Note which sealant went where at handover
- Brief the final clean team to avoid blades near sealant
- Allow flexibility for external sealing in damp or cold weather
- Use the product the specification names
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. We can confirm the handover information you need when we quote.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Several jobs near Emmbrook can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- 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.
Preparing the site
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000
- Flag any permit to work we will need

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Why deal with it now?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
A quote for mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Honest limits
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Frame gaps too wide for sealant, which the installer needs to correct
- Joint design decisions that belong to the architect or engineer
- Approving fire stopping as compliant
