Construction mastic in Sheerwater, done properly
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you are dealing with sanitary sealant damaged by following trades and inconsistent sealant finishes from plot to plot, we can put it right. A single leaking joint is often how a building in Sheerwater first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Conversions of older rural buildings near smaller places such as Sheerwater bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. For a building around Sheerwater, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
- Warn occupants and staff about the work

What happens if it’s left?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption. Snagging can be priced as a separate stage. Older rural buildings around Sheerwater move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- Work carried out by CSCS-carded applicators
- RAL and finish matching where the product range allows
- Colour options checked against the specified product
- Fully insured, including public liability cover

Looking after the joints
After handover, these steps help:
- Brief following trades on areas that have been sealed
- Use the product the specification names
- Keep scrapers and abrasive pads off new beads
- Release areas for mastic once other trades have finished in them
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks, so we plan external work with that in mind.
Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Your questions answered
Is a hospital such as Nuffield Health Woking Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work around term dates at a campus such as Woking College?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
Mastic packages on Sheerwater sites
Sheerwater is about 22 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. The area within 2 miles of Sheerwater holds several hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Projects at colleges like Woking College (2 miles south-west of Sheerwater) tend to run to term dates, so the mastic is planned tightly. Units on estates such as Kingsway Business Park, under half a mile south-west of Sheerwater, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. New wings at hospitals like Nuffield Health Woking Hospital, 1.4 miles to the west of Sheerwater, bring long runs of window and panel joints to seal.
Sheerwater is about 2 miles north-east of Woking, in Surrey. Any commercial site in Sheerwater is covered, for single jobs and planned programmes alike. Sheerwater is one of 379 places we cover in Surrey. Our Reading page has more on work in that area.

When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal
- Cladding and panel joints
- Brick and block movement joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
Different surfaces, different methods
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room.
