About our construction mastic in Southwater
Site managers want applicators who turn up with the right cards and paperwork. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We work on cladding and panel joints, floor and skirting junctions and window and door perimeters, and the failures we’re asked to look at most are cracks opening in caulked internal joints and inconsistent sealant finishes from plot to plot. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Southwater, preparation and product choice get the time they need.
For a contractor on a smaller site near Southwater, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Work in places the size of Southwater is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions

Advice
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Facades, frames and programmes in Southwater
Central London is about 34 miles from Southwater. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Southwater is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at schools like Southwater Infant Academy work to term dates, so mastic is programmed tightly. Extensions at sites like Horsham Hospital, 3.2 miles north of Southwater, typically sit beside working departments, and the mastic follows strict access rules. New units and refits on sites such as Southwater Business Park, less than half a mile to the south-west of Southwater, need their panel and perimeter joints sealed to the specification.

Southwater: questions and answers
Is Southwater Business Park, near Southwater, within your area?
Yes. Our area takes in Southwater and its surroundings, with estates and business parks such as Southwater Business Park included. A few photos and the unit address let us price the work.
Do you take on work at healthcare sites like Horsham Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Is Southwater in your area?
Yes. Sites across Southwater are covered.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Why deal with it now?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. If the frame is life-expired, we will tell you. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

After the work
After handover, a little attention goes a long way:
- Keep finished joints away from paint, plaster and scrapers
- Share drawings and the specification as soon as possible
- Keep product details for future maintenance
- Keep scrapers and abrasive pads off new beads
Record which products went where in the handover file. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
