How we handle construction mastic in Shellwood Cross
Mastic follows everyone else, which means it absorbs every delay upstream. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. The enquiries we see most involve sealant knocked or painted over by other trades and a mastic package split between trades with no clear owner, across cladding and panel joints, window and door perimeters and floor and skirting junctions. For commercial sealant work in Shellwood Cross, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Sites around smaller places like Shellwood Cross 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.
Our 12-month guarantee is about workmanship, not 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.

What the job involves on each surface
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. We check them during the first walk-round and flag any that need packing or adjusting.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
Facades, frames and programmes in Shellwood Cross
At about 22 miles from central London, Shellwood Cross is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Shellwood Cross is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.
Sites around Shellwood Cross get mastic sealed to the drawings and the programme, nothing improvised.

Why deal with it now?
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Leave it late and they turn up on the snag list. Halls, stores and units around places like Shellwood Cross may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Keep product details for future maintenance
- Keep finished joints away from paint, plaster and scrapers
- Allow flexibility for external sealing in damp or cold weather
- Ask installers to correct oversized gaps first
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We raise them during our first walk of the area.
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates, and we clear our waste as we work. Rural sites near Shellwood Cross may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.

Quoting for work in Shellwood Cross
We price every job individually. The things that drive the figure:
- Distance, for remote addresses
- Joint width, depth and condition
- Whether old sealant has to be cut out first
- How much there is to seal
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
Good information means a firmer quote. Helpful details to send:
- Whether an asbestos survey exists
- The postcode of the building
- Access details, including height
- A wide shot and a close-up of the area
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Your questions answered
Is Shellwood Cross too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is hospital work, at somewhere like East Surrey Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
How long does a typical visit take?
It depends on the scope, though a typical visit normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. For bigger or phased jobs, we will set out a timescale with the quote.
Can you clear a mastic snag list before handover?
Yes. We clear snags by redoing joints rather than patching them.
Can you work plot by plot or floor by floor?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team and updated as the programme moves.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email drawings and photos. Include photos or drawings if you have them.
What happens if the weather stops external sealing?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems.
When to call us in Shellwood Cross
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
Most enquiries start with one or more of the following:
- Inconsistent sealant finishes from plot to plot
- Perimeter gaps outside the sealant’s range
- Missed perimeter joints on a new elevation
- Sanitary sealant damaged by following trades
On a healthcare site such as East Surrey Hospital, which lies east of Shellwood Cross, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
