Coloured sealant in Southwick, done properly
Colour-matched joints are often among the last items before handover. We work around other trades and protect adjacent finishes. Our workmanship carries a 12-month guarantee. Site teams most often ask us about old colour-matched joints lifting at the edges and sealant that no longer suits recoated frames, across hotel bathrooms and public areas, natural stone and brick and cladding panels. A single leaking joint is often how a building in Southwick first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places such as Southwick, small firms often work from converted barns, yards and rural units. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits
Being straight saves everyone time. New sealant won’t cure:

Looking after the joints
A few simple habits keep the new joints working:
- Avoid abrasive pads on coloured sealant
- Protect fresh coloured sealant from dust and handling
- Record the product and colour reference on the building file
- Keep the same sealant colour across a brand
Use gentle cleaning methods on coloured sealant. Harsh chemicals and scouring can change how the colour looks over time.
Standardise the sealant colour on multi-site work. It keeps repairs and new sites consistent for whoever reseals next.
Why act early in Southwick
A brand roll-out or multi-site fit-out benefits from a consistent sealant colour. Setting one product and colour for every site avoids variation. Small buildings around Southwick suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Pricing colour-matched joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Questions about Southwick
Is Southwick too small for you to travel to?
No. Places such as Southwick are covered as much as the big towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Our building in Southwick is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you take on colour-matched sealant for shop fits and multi-site roll-outs?
Yes. We work with shop fitters, hotel groups and office fit-out contractors. Sites anywhere in our area, from London and the South East to Scotland, can be included, so a consistent colour can run across several sites.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Frontages, fit-outs and joints in Southwick
Southwick lies within about 1 mile of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. Central London is about 46 miles from Southwick. Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all.
For a shop at a centre such as Goldstone Retail Park, 2.7 miles east of Southwick, tidy joints at counters and displays matter as much as the fixtures. For premises near Southwick station, less than half a mile south of Southwick, footfall is part of the plan: work is phased so shops and offices keep trading. A unit on an estate like Grange Industrial Estate (to the south-west of Southwick) usually has an office front, a trade counter and staff facilities with joints of their own.
