On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Shopwyke are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- 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.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits

Construction mastic in Shopwyke, done properly
We work to the specification and the programme. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. Site teams most often ask us about oversized or tapered gaps around new frames and snag items on joints that need redoing before handover, on window and door perimeters, cladding and panel joints and internal decorators’ caulk. Most enquiries from Shopwyke start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in and around smaller places such as Shopwyke is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
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’re clear about what is covered before work starts.

Signs you need construction mastic in Shopwyke
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens.
Common reasons buildings call us in:
- Inconsistent sealant finishes from plot to plot
- Existing joints on a refurb that need cutting out and resealing
- Early adhesion failures on new external joints
- Caulk cracking where joints are moving more than expected
For contractors at a college like West Sussex Alternative Provision College (2.2 miles south-west of Shopwyke), perimeters and internal sealant are timed for the holidays.

- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

- Deciding which fire-stopping product a penetration needs

FAQs: Shopwyke
Is Shopwyke too far out for you?
Not at all. Shopwyke is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is hospital work, at somewhere like St Richard's Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
What joints do you seal on a new build?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Get the mastic subcontractor involved early in the programme
- Put any product change through the designer first
- Bring the mastic contractor in after the last trades are through
- Check frame gaps are within the sealant’s range before sealing
After we have sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.

Different surfaces, different methods
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services. Tell us what records you need and we’ll confirm with the quote.
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room and damaged joints are redone rather than patched.
Facades, frames and programmes in Shopwyke
Shopwyke is about 53 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Shopwyke sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
For a contractor working at a hospital such as St Richard's Hospital (1.3 miles west of Shopwyke), perimeter and facade sealing is planned around patients and deliveries. When a school such as Westbourne House School is extended or refurbished, the mastic package is often squeezed into the holidays.
Shopwyke is about 2 miles east of Chichester, in West Sussex. Anywhere in PO20, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.
