Cadmore End Commercial Sealant
Problem with your washrooms, bathrooms and kitchens in Cadmore End? We remove the old material, prepare the joints and seal them properly.
- Washrooms that need sorting before an inspection
- Mouldy bathrooms flagged at a tenancy check
- Silicone laid over old silicone by a previous contractor
Why deal with it now?
Sealant work is quick by the room: the job takes a few hours for a single washroom, longer for a whole building. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Around Cadmore End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear quote before we start.

Commercial sealant around Cadmore End
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a church, hall or community building such as Church of St Mary Le Moor, halls and community kitchens see heavy use, and their sealant shows it. If you let a flat or house near Saunderton station, we can quote for one property or a whole portfolio of rentals. If you look after a building such as Cadmore End CofE School, washroom and kitchen sealant can be programmed around term times or opening hours.

How we quote for commercial sealant
For a quick quote, just ask. The main things that affect it are:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- How much there is to do
- How much old sealant there is and how hard it is to remove
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
There’s no need for technical detail. Just tell us:
- The rough size of the job
- How we’d reach the joints
- The type of property
- Any previous sealing or DIY work
We don’t publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Don’t leave a failed joint until the next refurbishment
- Ask cleaners to go gently on the silicone
- Check the joints during routine room inspections
- Give housekeeping the cure time for every room
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.
What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Somewhere like Cadmore End needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we visit and agree the scope, the sequence and the working hours.
- Every area is sheeted and the old silicone stripped out.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Each room is checked and handed back with its cure time.
Before we arrive
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
