Commercial sealant in New Cross, done properly
Staff facilities cannot be out of action for long. Early starts and out-of-hours work can be arranged so the working day is disturbed as little as possible. You are told when each area can be used again. If you are dealing with shower leaks reaching the floor below and black, stained silicone in guest bathrooms, we can put it right.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in New Cross, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Faulty shower valves and leaking traps
- Damaged sanitaryware that needs replacing
- A broken extractor fan behind the mould problem
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, keeping disruption down and costs clear. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in New Cross, the repair is bigger than a sealant job.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

Commercial sealant in New Cross: local notes
There are hotels and other places to stay in and around New Cross. Hotel work can be planned room by room, with out-of-hours working where needed. London has hard water, which leaves limescale on sealant, grout and taps.
For site and facilities teams at buildings such as Myatt Garden Primary School, washroom and kitchen sealant can be programmed around term times or opening hours. As a London address, New Cross can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Common questions in New Cross
I let a flat near New Cross station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is parking a problem for a job in New Cross?
Parking in New Cross, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you reseal hotel rooms while we stay open?
Yes. We agree the room order and times with your managers, and you will know when each room can be used.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Can you supply method statements and risk assessments?
We are fully insured, and we’ll go through your site’s requirements with you. Send over your requirements and we will confirm what we can provide.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Aftercare tips
To keep the joints looking good and working properly:
- Act on lifting sealant before it leaks
- Note the date each area was done
- Keep extractor fans working and serviced
- Add sealant to your planned maintenance checks
We give a cure time for every area we finish, usually around 24 hours. Pass it on to housekeeping or cleaners so the new sealant isn’t wetted or scrubbed too soon.
Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.

How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on the number of rooms. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in New Cross. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- We let your team know the cure time for every area.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

Advice
What we are called out for in New Cross
Commercial buildings settle and move with temperature, and lightweight partitions flex more than masonry. Joints between different materials take the strain.
Signs it’s time to call us include:
- Leaking joints in shower rooms and changing areas
- Rental bathrooms that need resealing between tenants
- Black, stained silicone in guest bathrooms
- Sealant failing again soon after quick repairs
Rented homes near New Cross station change hands often, and we can quote for one property or a whole portfolio of rentals.
What your quote should include
- Whether all the old sealant comes out first
- When the joint can take water or movement
- How the colour is chosen
- Whether the sealant suits the joint
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
