Advice
Construction mastic in Gay Street
The specification and the programme set the job. 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 detail on the drawing is what ends up on site. We work on brick and block movement joints, cladding and panel joints and sanitary and kitchen joints, and the usual reasons a site gets in touch are caulk cracking where joints are moving more than expected and inconsistent sealant finishes from plot to plot. A single leaking joint is often how a building in Gay Street 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.
Construction in and around smaller places such as Gay Street is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out in West Sussex comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or use the quote form and we will arrange a return visit.

What the job involves on each surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
When to call us in Gay Street
On construction sites, joints typically fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, so they end up back on the snag list.
Most enquiries start with one or more of the following:
- A long mastic snag list close to completion
- External joints sealed in damp or cold conditions that are now failing
- Internal caulk splitting as the building dries out
- Bath and shower joints scraped during the final clean
Projects at colleges like Brinsbury College (to the north-west of Gay Street) tend to run to term dates, so the mastic is planned tightly.

Will you take on work at estates like Broomers Hill Business Park, close to Gay Street?

Do you work in Gay Street?
Yes. We take on work across Gay Street, and the same phone number covers every area.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you guarantee new-build sealant work?
It’s backed by our 12-month guarantee. Keeping other trades off finished joints prevents most problems.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
When to bring in a specialist
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.
Putting right a botched joint often costs more than sealing it well at the start, 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.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Joints damaged after sign-off by following trades
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
What we seal
- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
- Brick and block movement joints
- Internal decorators’ caulk
- Floor and skirting junctions
New build and refits around Gay Street
At about 40 miles from central London, Gay Street is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Gay Street sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.
For contractors refurbishing units at places like Broomers Hill Business Park (1.4 miles west of Gay Street), the mastic covers cladding panels, roller-door and window perimeters. Older buildings in the area around Gay Street, such as Old Place Manor, which lies south-west of Gay Street, need care when sealed: the product has to suit soft or historic materials.
Gay Street is about 9 miles south-west of Horsham, in West Sussex. Businesses, contractors and managing agents in Gay Street can call on us for mastic packages, as part of our coverage of West Sussex. Gay Street is one of 373 places we cover in West Sussex.

Why it’s worth doing now in Gay Street
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Leave it late and they turn up on the snag list. One visit to deal with every failing joint makes more sense than several trips to a place like Gay Street. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
