Your questions answered
Will you plan work around the academic year at somewhere like Fareham College?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work on a hospital site such as Fareham Community Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you quote from photographs?
It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Is there a guarantee on the work?
Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
Will all the toilets be closed at once?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured, then we move on.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Advice
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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, which is what makes a joint last.
Why act early in Segensworth
Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Converted and older buildings near places like Segensworth tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Squeegee showers and trays after busy periods
- Make sure washroom ventilation is running
- Respect the cure time before reopening each room
- Include joints in routine washroom inspections
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.
A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job and more closures to manage.
When to call us in Segensworth
Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.
Things that usually lead to an enquiry:
- Split or peeling sealant at shower trays
- A new bead over an old one coming away
- Kitchen worktop joints that can’t be kept clean
- Complaints from staff, guests or users about tired washrooms
Colleges such as Fareham College (to the south-east of Segensworth) have toilets, changing rooms and catering kitchens that can be resealed around term dates.
