Washroom sealing for Charlton sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Once the work is signed off, these steps help:
- Act on the first split you see at a shower tray
- Don’t leave trays and floors sitting wet
- Photograph and log failed joints across the estate
- Keep washrooms out of use until we say the sealant has cured
Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.
Washroom sealing for commercial buildings in Charlton
In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. We work on kitchens and tea points, urinals and WCs and vanity units and basins, and the usual reasons a site gets in touch are shower tray joints that have opened up and stained sealant around pans and urinals. Most enquiries from Charlton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Charlton still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.
Our workmanship is guaranteed for 12 months, in Charlton as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Our process
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Charlton are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- We strip out the old bead and clean off the residue left behind.
- We clean and dry every surface so the new sealant can grip.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Rooms reopen after the product’s cure time, and we move to the next.
Before we start on site
- Confirm the product named in the specification
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work

Washroom sealing in Charlton: the local picture
At about 49 miles from central London, Charlton is within reach of the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.
At a hotel such as Woodstock House Hotel (under half a mile north of Charlton), the quieter weeks are the time to reseal bathrooms. Halls of residence and teaching buildings at universities such as University of Chichester (4.7 miles south of Charlton) are easiest to reseal during vacations. Church halls and community buildings, such as those at The Parish Church of the Blessed Virgin Mary, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

General trades versus a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When it isn’t the sealant
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
- Loose panels, vanity units or tiles, which need fixing first
If you are not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.

How the quote is worked out
We price every job individually. The main factors are:
- The product specified
- The site’s rules and procedures
- Travel to remote or island sites
- Access and working height
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 we will put a fixed figure on it.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- The product your specification calls for
- Drawings or a marked-up plan, if available
- When you need the work done
- Clear photos of the problem areas
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Charlton: questions and answers
Can you take on a job at a hospital such as Chichester Centre?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can you work around term dates at a campus such as University of Chichester?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What about RAMS and site documents?
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.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
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 facilities are never short.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
