Aftercare tips
To keep the joints looking good and working properly:
- Keep a record of which rooms were resealed and when
- Keep extractor fans working and serviced
- Do not leave a failed joint until the next refurbishment
- Use mild cleaners on sealant, not bleach or abrasives
Include sealant in routine room inspections. A quick look at each bathroom when rooms are checked spots problems early.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.
What commercial sealant looks like in Wexham Street
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Community buildings like St Andrew's Church Centre are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. If you look after a building such as Khalsa Secondary Academy, washroom and kitchen sealant can be programmed around term times or opening hours. For landlords with property near Slough station, we can quote for one property or a whole portfolio of rentals.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How the visit works
At the end, we look at the finished work together. The visit itself normally takes a few hours for a single washroom, longer for a whole building, depending on the amount of work. Somewhere as small as Wexham Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with a site walk to agree the rooms and the timing.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Rooms are checked and returned with a cure time so staff know when to use them.
Preparing for the visit
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

How we quote for commercial sealant
We don’t publish a price list, because jobs vary so much. The quote depends on:
- When we can work, for business premises
- Mould in or behind the old joints
- The type of sealant required
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- A few photos by email, if you can
- Where the property is
- The problem you’ve noticed
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Common questions in Wexham Street
Do you cover smaller places like Wexham Street?
Yes, Wexham Street is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Wexham Street in your area for commercial sealant?
Yes. We work across London and the South East, and Wexham Street is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
How long does commercial sealant take?
As a guide, most jobs take a few hours per room, so whole buildings are phased. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Do you guarantee commercial jobs?
Yes. Every job, domestic or commercial, carries our 12-month guarantee.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Is out-of-hours working possible?
Out-of-hours work and early starts can be arranged. Tell us what you need when you ask for a quote.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you reseal bathrooms across several rental properties?
Yes, we can. Send us the addresses and what needs doing, and we’ll quote for the lot.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Tiles coming off the wall
- Cracked trays or baths rather than failed joints
- Assessing what fire stopping a building needs
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Hotel bathrooms
- Rental portfolios
- Retail & leisure sites
- Welfare facilities
- Student & care accommodation
- Office washrooms & kitchens
Why act early in Wexham Street
Sealing over the old bead can seem the fastest option, but it won’t bond, and it lifts again soon. Doing it properly once is less disruptive than doing it badly twice. In a small place like Wexham Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
