Commercial Sealant in Cosham

- Joints that need doing before an inspection or audit
- Split sealant around staff kitchen worktops and sinks
- Washroom sealant that looks dirty however often it’s cleaned
Commercial sealant in Cosham
Commercial work is planned around the building, not the other way round. We can work room by room, floor by floor or in batches, and out-of-hours work or early starts can be arranged where it helps. We work on retail & leisure sites, rental portfolios and student & care accommodation, and the jobs we see most are tired sealant ahead of a health and safety audit and shower leaks reaching the floor below.
Around a place like Cosham, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.
Your job is guaranteed for a year, as with all our work.

Landlords, agents and businesses in Cosham
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Damaged sanitaryware that needs replacing
- Water coming from plumbing rather than sealant
- Poor ventilation that keeps bringing mould back
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Commercial buildings in Cosham
If you run a hotel, guest house or holiday let in a coastal place like Cosham, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Court Lane Junior Academy, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. For landlords with property near Cosham station, several rental properties can be resealed on one programme.
Cosham is about 2 miles south-west of Purbrook, in Portsmouth. Across the PO6 area, we can carry out commercial sealant at your property. Cosham is one of 19 towns and villages in Portsmouth we cover.
Every address in PO6, PO3 and PO2 is within our area for commercial sealant. Local streets include Dean Road, Park Lane and Elgin Road. With the A397 close by, Cosham is easy for our applicators to reach. Close by, we work in Wymering (1 mile north-west), Hilsea (1 mile south), Drayton (1 mile east), Widley (1 mile north-east) and Paulsgrove (1 mile west). Further out, we also cover Southsea (4 miles south), Milton (3 miles south), Landport (3 miles south), Portsea (3 miles south-west), Portsmouth Point (4 miles south-west) and Fratton (3 miles south).
What’s near Cosham
Around Cosham, our work takes us to homes and buildings near The First Post pub, Alexandra Park and Springfield School, among other places. There’s a railway station in Cosham itself: Cosham station. Nearby you will also find Tricorn Centre (2.9 miles south) and World War I Remembrance Centre (1 mile south-east). Not far away are Southmoor Nature Reserve and Portsdown Hill.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep strong chemicals and scourers off the joints
- Act on lifting sealant before it leaks
- Check extract fans are actually running
- Put a squeegee in each shower
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
Common problems we fix in Cosham
Heavy use means more movement: different weights, constant use and daily cleaning all work at the joint. If a tray flexes, the sealant around it splits.
Keep an eye out for these signs:
- Tired sealant ahead of a health and safety audit
- Water marks on ceilings under bathrooms
- Failed floor-level joints in accessible wet rooms
- Rental bathrooms that need resealing between tenants
If you look after a church, hall or community building such as Church of St Philip, its kitchen and washroom sealant needs looking after like anywhere else.

What affects the cost of commercial sealant
We don’t publish a price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- Whether there’s mould to deal with
- Access and height
- When we can work, for business premises
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- How we’d reach the joints
- The rough size of the job
- Whether it has been sealed before
- What’s wrong with the joints now

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
