About our construction mastic in Waterbeach
Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on sanitary and kitchen joints, brick and block movement joints and floor and skirting junctions, and the failures we are asked to look at most are caulk cracking where joints are moving more than expected and mastic snags holding up handover. One point of contact handles commercial sealant work in Waterbeach from the first photographs to the final walk-round, whether it’s one building or several.
Sites around smaller places like Waterbeach can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Joint design decisions that belong to the architect or engineer
- Frames fitted out of tolerance
- Glazing units that are cracked or misted
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Sites and facades in and around Waterbeach
Rainfall across the South East, Waterbeach included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Waterbeach is about 52 miles from central London. 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.
Recladding or extending a unit at a site like Temple Bar Business Park (to the south of Waterbeach) brings panel joints and frame perimeters into the programme. University estates such as University of Chichester, 2.3 miles to the south-west of Waterbeach, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a school such as Boxgrove CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Waterbeach is about 3 miles north-east of Chichester, in West Sussex. We cover commercial sites throughout Waterbeach, whether it’s a single job or part of a planned programme. Waterbeach is one of 373 places we cover in West Sussex for mastic packages. There’s a separate page for Portsmouth, about 16 miles away.
We cover the PO18 postcode districts. Just outside Waterbeach, we also work in Strettington (1 mile south), Westerton (1 mile south-west), Halnaker (1 mile east), Boxgrove (1 mile south-east) and Maudlin (1 mile south). Further afield, our area takes in Worthing (15 miles east), Bognor Regis (6 miles south), Chichester (3 miles south-west), Selsey (9 miles south), Littlehampton (10 miles south-east) and Rustington (11 miles east).

Other services in Waterbeach
Diagnose, treat, sign off
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Waterbeach are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- 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.
Preparing the site
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Point out parking and an unloading spot

Advice
Maintenance after handover
After handover, a little attention goes a long way:
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Stick to the specified sealant rather than a generic substitute
- Share drawings and the specification as soon as possible
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
Your questions answered
Would you work within a site like St Richard's Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Could you schedule work at a campus like University of Chichester for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Do you use the sealant named in the specification?
We work to the specification and the manufacturer’s installation guidance. Preparation, backing and depth follow the product guidance.
What do you charge?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or email drawings and photos.
What happens if old sealant might contain asbestos?
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.
Do you take on mastic snagging only?
Yes. Snag-only work is something we take on, cutting out damaged or poor joints and resealing them.
How the job changes by surface
External facade and movement joints
Many facade substrates need a primer before sealing. 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.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Waterbeach can sit alongside others in a wider programme.
Cost factors for mastic packages
What shapes the price:
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- How accessible the joints are
- Phasing around occupants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- Specification clauses that apply
- Whether the building will be occupied during the work
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
