How we handle commercial sealant in Old Windsor
Mouldy or split sealant in a commercial building causes more than a bad impression. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on office washrooms & kitchens, student & care accommodation and rental portfolios, and common reasons people get in touch are large numbers of bathrooms needing the same work and shower leaks reaching the floor below.
In a smaller place like Old Windsor, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. The work is the same as in a big building, just on a smaller scale.
Every job is covered by our 12-month guarantee.

Landlord and commercial work in Old Windsor
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
The process
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours per room, so whole buildings are phased, and we tell you how long to leave it before we go. In a smaller place like Old Windsor, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Advice
Commercial buildings in Old Windsor
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Sunnymeads station change hands often, and several rental properties can be resealed on one programme. If you look after a building such as King's Court First School, busy washrooms and kitchens can be resealed in phases so they stay open.

Different surfaces, different methods
Welfare facilities
Welfare facilities, shower rooms and changing areas need to stay usable. Work can be split into sections so some facilities stay open.
Retail & leisure sites
Customer toilets reflect on the business, and clean, neat sealant makes them look cared for.
Why deal with it now?
Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. We’ll tell you if we find anything that needs another trade. In an older home around Old Windsor, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we will talk you through it.

Take a look at what affects the cost and what customers say.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Common questions in Old Windsor
Can you do commercial sealant in Old Windsor?
Yes. We work across London and the South East, and Old Windsor is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Sunnymeads station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you work outside opening hours?
In many cases. Let us know when the building is quietest, and we will see what can be arranged.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you take on large, multi-room jobs?
Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.

What else we do in Old Windsor
What affects the cost of commercial sealant
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Access and height
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- How many areas need sealing
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
There’s no standard price list, because every job is different. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or email us.
When to call us in Old Windsor
Internal washrooms and en suites without a window rely entirely on extraction, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.
Keep an eye out for any of the following:
- Worktop sealant that has shrunk and stained
- Whole floors of tired en suites
- Tired sealant in let properties
- Repeated reseals that do not last
Community buildings like St Luke are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.
