About our commercial sealant in Eltham
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can go on one quote. If you are dealing with rental bathrooms that need resealing between tenants and water marks on ceilings under bathrooms, we can help, whatever the surface.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Eltham, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Why it’s worth doing now in Eltham
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 London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Eltham.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.

Workplaces and buildings in Eltham
London’s water is hard, which leaves limescale on sealant, grout and taps. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
Community buildings like Church of Holy Trinity are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. As a London address, Eltham can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Mottingham station? Then sealant work can be quoted for a single flat or a whole portfolio.

Questions from Eltham
Can parking be tricky for a visit in Eltham?
Parking in Eltham, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Mottingham station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Where are you based?
We work from Crawley. We cover Eltham and the rest of Greater London, along with the rest of our area.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Does commercial work come with a guarantee?
Yes. Our 12-month guarantee covers commercial work too.
When something else is needed
We’ll always be straight with you, so here’s what sealant can’t fix:
- Faulty shower valves and leaking traps
- Assessing what fire stopping a building needs
- Damaged sanitaryware that needs replacing
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Retail & leisure sites
- Hotel bathrooms
- Rental portfolios
- Student & care accommodation
- Office washrooms & kitchens
- Welfare facilities
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Schedule work around occupancy
- Keep a record of which rooms were resealed and when
- Include the silicone on your room checklists
- Get split or lifting joints looked at early
Add sealant checks to your planned maintenance. A quick look at each bathroom when rooms are checked spots problems early.
Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
Work for landlords, hotels and businesses
Landlords and letting agents in Eltham can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Different surfaces, different methods
Hotel bathrooms
Early starts or out-of-hours work can be arranged around check-out and check-in.
Welfare facilities
Busy staff showers wear sealant out quickly. We reseal with anti-fungal sanitary silicone, accessible showers included.
The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a single washroom, longer for a whole building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

What else we do in Eltham
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
