What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Panel boards already damaged by water
- Mould caused by poor ventilation, which will return until the extract is fixed
If you’re not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Vanity units and basins
- Urinals and WCs
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Kitchens and tea points
- Showers, trays and wet room floors
Washroom sealing in Blackwater
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. We work on showers, trays and wet room floors, accessible toilets and changing rooms and urinals and WCs, and what we are called in for most is a new bead over an old one coming away and sealant stained black around basins and showers. A specialist sealant contractor works differently from a general builder: on jobs in Blackwater, preparation and product choice get the time they need.
In and around places like Blackwater, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Cost factors for washrooms and wet areas
Quotes vary with the job. Expect it to depend on:
- Backing rod, priming and other preparation
- How much there is to seal
- How accessible the joints are
- Which sealant the job calls for
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Specification clauses that apply
- Access details, including height
- Your programme or deadline
- Asbestos survey details if the building is older
To get a fixed quote, speak to us on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. You can also send details through our quote form.
General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. 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.
Common questions from Blackwater clients
Does a hotel in Blackwater need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Do you take on work at healthcare sites like Frimley Park Hospital?
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.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
What sealant do you use in washrooms?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.
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.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Surface by surface
Kitchens and tea points
In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Where food contact is possible, we use a hygienic, food-safe sealant.
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.

How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Blackwater need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- 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.
- New anti-mould sealant goes in and is tooled neat.

When to call us in Blackwater
Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.
Most enquiries start with something like this:
- Stained or open joints at kitchen sinks and worktops
- Open joints along basins and vanity units
- Washrooms that look worn because of the sealant
- Sealant laid over old silicone and now peeling
At a college such as The Sixth Form College Farnborough, which lies south-east of Blackwater, washroom and kitchen sealant is best renewed in the holidays or in phases during term.
What to look for in a quote
- Their approach to joint depth and backing
- Who will actually carry out the work
- Health and safety accreditation such as CHAS
- Will failed sealant be removed rather than covered?
Wet areas in Blackwater’s workplaces
