Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed
- Leaks through tanking or membranes below the finishes
Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly before you book.
Joints and surfaces we work on
- Vanity units and basins
- IPS panels and cubicles
- Kitchens and tea points
- Showers, trays and wet room floors
- Urinals and WCs
- Accessible toilets and changing rooms
Washroom sealing in Heyshott, done properly
When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. If you are dealing with failed joints along IPS and cubicle panels and discoloured joints around urinals and WC pans, we can put it right, whatever the surface.

Washroom sealing in Heyshott: the local picture
Heyshott lies roughly 46 miles out from central London. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.
On a healthcare site such as Midhurst Community Hospital, 2.9 miles to the north of Heyshott, washroom work starts with the infection-control team’s sign-off. Units at estates like Holmbush Industrial Estate (to the north-west of Heyshott) have welfare blocks whose showers and toilets see shift after shift. For a hall at a building such as The Parish Church of St James, resealing the kitchen and toilets can be fitted between bookings.

Why act early in Heyshott
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Older rural buildings around Heyshott move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What the job involves on each surface
Wet-room floors and floor-to-wall joints
We seal the visible joints; we don’t install or repair waterproofing below and point it out if water appears to rise from below.
Basins and vanity tops
Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Heyshott, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Confirm the product named in the specification
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email the details over.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Cost factors for washrooms and wet areas
The price varies from site to site. It mainly depends on:
- Quantities, in metres or numbers
- Whether the work must be split into stages
- The site’s rules and procedures
- Removal of failed or old sealant
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- The postcode of the building
- The asbestos register, for older buildings
- When you need the work done
- What the building is and how it’s used
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Questions we are asked in Heyshott
Is hospital work, at somewhere like Midhurst Community Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will all the washrooms in our Heyshott building be closed at once?
Not all at once. We take one block of facilities at a time. Each area is handed back once the sealant has cured enough to use.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Is there a guarantee on the work?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
How soon can a washroom be used after resealing?
Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.

Yes. Heyshott falls within our area, and you can call the office on 01277 525 020 or use the quote form to get started.
