Coldharbour: questions and answers
Can work at a site such as University of Sunderland in London fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work in a care home near Coldharbour with residents in?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Is old silicone taken out first?
The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.
Do you work in Coldharbour?
Yes. We take on work across Coldharbour, with one number for every area we cover.
Is there a guarantee on the work?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Washroom sealing for commercial buildings in Coldharbour
From one staff toilet in Coldharbour to washrooms across a whole estate, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. Site teams most often ask us about failed sealant behind washroom basins and open joints at the base of cubicle panels, on vanity units and basins, kitchens and tea points and accessible toilets and changing rooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Coldharbour is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Coldharbour, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Surface by surface
Wet-room floors and floor-to-wall joints
Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.
Healthcare and care settings
Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.
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: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
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 dripping waste or valve behind a panel
- Failed tanking beneath a wet-room floor or behind tiles
- Condensation from failed extract fans
If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Joints and surfaces we work on
- Urinals and WCs
- Accessible toilets and changing rooms
- Vanity units and basins
- Kitchens and tea points
- Showers, trays and wet room floors
- IPS panels and cubicles
Why deal with it now?
Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. In Coldharbour, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Coldharbour, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Joints are cleaned, degreased and dried before sealing.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed
- For older buildings, check the asbestos register before work
