Commercial Sealant in Egham
We cover Egham for sealant work for offices, hotels, washrooms and commercial buildings. Old material cut out, joints cleaned and sealed neatly.
- Split sealant where wet room floors meet walls
- Failed joints in office kitchens and tea points
- Silicone laid over old silicone by a previous contractor
How we handle commercial sealant in Egham
Staff facilities cannot be out of action for long. Early starts and out-of-hours work can be arranged to keep disruption down. You are told when each area can be used again. We work on rental portfolios, student & care accommodation and retail & leisure sites, and the jobs we see most are shower leaks reaching the floor below and too many rooms to reseal without closing the building.
For anyone managing a school, care home, pub or office in Egham, the sealant in its washrooms and kitchens, and the fire-rated joints around its pipework, all need looking after. Work can be planned around opening hours where needed.
A one-year guarantee comes as standard.

Do you need commercial sealant in Egham?
Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. Worktop and sink joints are often the first to go.
Most people get in touch when they notice one of these:
- Tired sealant ahead of a health and safety audit
- Worktop sealant that has shrunk and stained
- Black, stained silicone in guest bathrooms
- Water marks on ceilings under bathrooms
If you look after a building such as Manorcroft Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.

Common questions in Egham
Is Egham in your area for commercial sealant?
Yes, Egham is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Do you take on hotel work around Egham?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you reseal bathrooms across several rental properties?
Yes. We reseal bathrooms and kitchens in rented homes, and we can quote for several addresses at once.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can you supply method statements and risk assessments?
We’re fully insured, and we will go through your site’s requirements with you. Send over your requirements and we’ll confirm what we can provide.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Tiles coming off the wall
- Certifying fire stopping or building compliance
- Damaged sanitaryware that needs replacing
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Rental portfolios

- Student & care accommodation
- Hotel bathrooms
- Retail & leisure sites
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes as long as the scope needs, from one welfare room to a full building, and the area is left clean. For a job in Egham, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Related advice
Looking after it afterwards
To keep the joints looking good and working properly:
- Schedule work around occupancy
- Check the joints during routine room inspections
- Report broken fans quickly
- Do not leave a failed joint until the next refurbishment
Keep the extraction running and maintained. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.
What the job involves on each surface
Hotel bathrooms
We can plan around check-out and check-in times, with the order agreed with your team.
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.
What happens if it’s left?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and scrubbing will not fix it. New sealant does. Around Egham, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Left alone, that means rot, damp and a bigger repair.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
