Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
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.
Sealant specialists in Southington
Commercial occupiers rarely want a floor out of action for sealant work. Work is scheduled around the site hours and access windows you give us; phasing keeps some washrooms, kitchens or entrances available while others are done. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on external facade joints, kitchen worktops and splashbacks and washrooms and tea points, and the failures we are asked to look at most are greasy, split joints in a kitchen or tea point and black mould through washroom sealant that won’t clean off. Most enquiries from Southington start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
A lot of what we do in Southington is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Southington is normally a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Aftercare for building managers
To get the most from the new sealant:
- Make sure ventilation in wet areas is switched on and working
- Check joints after other trades have worked nearby
- Keep a record of which joints were resealed and when
- Check the asbestos register before anyone disturbs old sealant in an older building
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. Should something look amiss, you can ring 01277 525 020 or send photos by email and send a picture.
Sealant installed at the same time usually fails in sequence. A few splits this year usually mean more next year so the whole run is worth inspecting. We’ll tell you which sealant joints need doing first and which can wait.
What Southington’s businesses ask us to seal
Southington is about 54 miles from central London. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Southington is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.
Industrial estates such as Ardglen Industrial Estate (3 miles west of Southington) have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Advice
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
When to call us in Southington
A split down the middle of the bead tells a different story. Typically the movement was too much for the sealant chosen. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.
Any of the following is a good reason to get the joints checked over:
- Wall and floor joints that have lost their seal
- Layers of sealant, all of them failing
- Black mould through washroom sealant that won’t clean off
- Leaks that seem to come through a sealant line
Shops and cafés around stations like Overton station, 1.1 miles north-east of Southington, trade from early, so work is timed around them.
What your quote should include
- How they handle RAMS and site documents
- Their pre-qualification and accreditations
- How joint depth will be controlled
- What the guarantee covers, and for how long
