Coloured sealant in St Mary's, done properly
Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building. On resealing, matching the existing colour is often as important as the seal itself. We work on natural stone and brick, hotel bathrooms and public areas and office fit-out finishes, and the failures we’re asked to look at most are stained or mouldy coloured joints in washrooms and patch repairs in several different colours. Most enquiries from St Mary's 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.
Places like St Mary's tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.
A 12-month guarantee applies to all our work in Southampton. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we’ll come back to it.

Why deal with it now?
A failed joint lets in water and dirt, whatever colour it is. Behind the bead, moisture can damage substrates and finishes. Small buildings around St Mary's suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Coloured sealant in St Mary's: the local picture
St Mary's lies within about 1 mile of the sea. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. A matched colour is only half the brief on an exposed frontage. Less than 3 miles from St Mary's there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.
On estates like Central Trading Estate (under half a mile south-east of St Mary's), the office and welfare end of each unit has its own sealant to maintain. A hotel such as Leonardo Hotel Southampton, less than half a mile to the north-west of St Mary's, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
St Mary's is about 1 mile south of Southampton, in Southampton. Any commercial site in St Mary's is covered. Our Southampton coverage takes in 30 places, large and small.

Locally, jobs take us to sites close to The Joiners pub, Woolston School and Houndwell Park and the streets around them. The nearest railway station is Southampton Central station, roughly 0.8 miles west of the centre.

Common problems we fix in St Mary's
Exposure takes its toll on colour. UV, grime and weathering alter how a bead looks after a few years, and an old match drifts. Resealing is the chance to reset the colour.
Clients normally get in touch after noticing something like this:
- Joints that need to match a new RAL frame colour
- Untidy coloured beads with ragged edges
- Marked sealant in hotel bathrooms
- Patch repairs in several different colours
Premises within reach of Southampton Central station, 0.8 miles to the west of St Mary's, often have busy frontages where joints are seen by everyone passing.

How the job changes by surface
Powder-coated and anodised frames
Window, door and shopfront frames in RAL colours often need a sealant to suit. The frame colour is checked against what the product is made in, and you confirm the choice.
Hotel interiors
Phased resealing lets rooms go back into use quickly. Tell us your site hours and access windows and we will plan around them.
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- A colour that never alters with age
- Finishes that change colour from one area to another
- Paint over sealant on joints that move too much
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.
