Washroom sealing in Nash Mills
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What sets the cost
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The size and state of each joint
- Any access equipment needed
- The total length or number of joints
- Whether the work must be split into stages
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Access details, including height
- Photos of the joints, close up and from further back
- The postcode of the building
- The asbestos register, for older buildings
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Common questions from Nash Mills clients
Would you work within a site like Hemel Hempstead Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work at a site such as West Herts College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
When can showers be used after new sealant?
Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.
Is it OK to put new silicone on top of the old?
The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you do washroom sealing in healthcare settings?
Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Condensation from failed extract fans
- Loose panels, vanity units or tiles, which need fixing first
- A dripping waste or valve behind a panel
Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Accessible toilets and changing rooms
- Urinals and WCs
- IPS panels and cubicles
- Kitchens and tea points
- Vanity units and basins
- Showers, trays and wet room floors
Different surfaces, different methods
IPS and cubicle panels
Panels flex slightly in use so the bead needs to cope with it. We check fixings before sealing.
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Leave signs up until the cure time is over
- Squeegee showers and trays after busy periods
- Don’t leave an open joint at a basin or tray
- Note failing joints building by building
Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
