Washroom sealing in Harpsden Bottom, done properly
In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve failed sealant in a tea point or staff kitchen and sealant lifting along a tray edge, on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors.

Signs you need washroom sealing in Harpsden Bottom
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water and they discolour and fail early.
Things that normally lead to an enquiry:
- Open joints along basins and vanity units
- Black mould inside silicone joints that cleaning can’t shift
- Stained or open joints at kitchen sinks and worktops
- Sealant lifting along a tray edge
Student showers at universities like University of Reading, 2.1 miles south of Harpsden Bottom, see more use than most, and their silicone shows it.
Before you book anyone
- What site paperwork they can supply
- Their approach to joint depth and backing
- Can the work be phased to keep areas open?
- Are they CHAS accredited or on Constructionline?

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For work around Harpsden Bottom, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.

Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Loose panels, vanity units or tiles, which need fixing first
- Water escaping beneath the floor rather than through a joint
- Water from plumbing, not from a joint
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
What we seal
- IPS panels and cubicles
- Accessible toilets and changing rooms
- Urinals and WCs
- Showers, trays and wet room floors
- Vanity units and basins
- Kitchens and tea points
General trades versus a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- Whether the work must be split into stages
- Quantities, in metres or numbers
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
Good information means a firmer quote. Helpful details to send:
- Access details, including height
- When you need the work done
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Maintenance after handover
For the best life from the joints:
- Inspect washroom sealant regularly
- Keep washrooms out of use until we say the sealant has cured
- Photograph and log failed joints across the estate
- Squeegee showers and trays after busy periods
Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.
Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.
Your questions answered
Could you schedule work at a campus like University of Reading for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will our hotel in Harpsden Bottom need to close for the work?
Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
When can showers be used after new sealant?
Cure times vary by product and temperature. You will get a reopening time for each area, and signs stay up until then.
