What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Swollen or delaminated boards behind panels or vanity tops
- Mould caused by poor ventilation, which will return until the extract is fixed
- A dripping waste or valve behind a panel
If you are not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- Kitchens and tea points

Leave it or put it right?
Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. In a town such as Egham, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Renewing them before water gets in protects the fabric.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
How a job runs
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a town like Egham, we try to group jobs for the same client into one visit. Tell us when the building is open and we will plan to suit.
- 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.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
What we need from you
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings

Common questions from Egham clients
Would you work within a site like Ashford 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 you work around term dates at a campus such as Royal Holloway University?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
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.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.

Commercial washrooms in Egham
Egham is about 20 miles from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open. A 2-mile radius around Egham takes in a good number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.
Toilets at colleges like Strode's College, less than half a mile north-west of Egham, take heavy use from students and staff alike. For a site such as Ashford Hospital, which lies east of Egham, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. At a hotel such as The Runnymede Hotel on Thames, which lies north-east of Egham, the quieter weeks are the time to reseal bathrooms.

After the work
Keep the joints in good shape with a few simple steps:
- Avoid scourers and harsh descalers on silicone
- Keep washrooms out of use until we say the sealant has cured
- Clear standing water from shower floors where possible
- Share your site rules when you send details
We hand each area back once the silicone has had the cure time the product needs. You will be told when showers and basins can be used again, and it helps if signs stay up until then.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.
