Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How we quote for commercial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The size of the job
- Whether there’s mould to deal with
- Access and height
- How much old sealant there is and how hard it is to remove
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the property is
- A few pictures by email, if you can
- Any access issues, like height or stairs
- The rough size of the job
We quote each job on its own, so start by telling us what you need. Just ring 0345 464 0079 or send us an email with the details, and photos are welcome.
Do you need commercial sealant in New Charlton?
A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.
The most common problems we see are:
- Rental bathrooms that need resealing between tenants
- Whole floors of tired en suites
- Leaking joints in shower rooms and changing areas
- Washroom sealant that looks dirty however often it’s cleaned
If you look after a building such as Royal Greenwich Trust School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
What your quote should include
- What product goes in the joint
- Are they insured?
- How the colour is chosen
- When the joint can take water or movement
What the job involves on each surface
Student & care accommodation
Many accommodation blocks have rows of similar en suites. A room-by-room programme keeps the job efficient.
Office washrooms & kitchens
Long vanity tops have joints that hold water and grime. It’s cut out, cleaned and resealed in one neat line.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- A broken extractor fan behind the mould problem
- Faulty shower valves and leaking traps
- Cracked trays or baths rather than failed joints
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.
Surfaces we seal
- Office washrooms & kitchens
- Hotel bathrooms
- Rental portfolios
- Retail & leisure sites
- Welfare facilities

Your questions about commercial sealant in New Charlton
Do you work for hotels and guest houses in New Charlton?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Is parking a problem for a job in New Charlton?
Parking in New Charlton, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does the job take?
As a guide, most jobs take a few hours for a single washroom, longer for a whole building. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a single washroom, longer for a whole building in most cases. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
What happens if it’s left?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. If something else is wrong, we’ll say so. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in New Charlton.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
