Commercial sealant in Rainham
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. Products include Arbo and Everbuild sealants, chosen to suit each joint. If you have tired sealant in let properties and split sealant where wet room floors meet walls, we can put it right, whatever the surface.

FAQs for Rainham
Can you do commercial sealant in Rainham?
Yes. Our work covers London and the South East, and Rainham is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Rainham (Essex) station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
How do I get a quote for commercial sealant in Rainham?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Is commercial work guaranteed?
Yes, for 12 months. Mild cleaning and good ventilation help it last.
What commercial sealant looks like in Rainham
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. London’s water is hard, which leaves limescale on sealant, grout and taps.
Schools such as Rainham Village Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open. For landlords with property near Rainham (Essex) station, we can quote for one property or a whole portfolio of rentals.

What we’re called out for in Rainham
In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.
The most common problems we see are:
- Failed joints in office kitchens and tea points
- Water marks on ceilings under bathrooms
- Failed floor-level joints in accessible wet rooms
- Too many rooms to reseal without closing the building
For buildings such as Church of St Helen and St Giles, its kitchen and washroom sealant needs looking after like anywhere else.
Questions to ask before booking
- What the cure time is
- How the colour is chosen
- Who does the work, and how experienced they are
- Is VAT in the price?
Why act early in Rainham
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. Dealing with it early is far simpler.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What else we do in Rainham
How to look after the new joints
To keep the joints looking good and working properly:
- Book larger programmes for quieter times of year
- Log resealing so you know what’s due
- Tell cleaning staff when each room can be used
- Include the silicone on your room checklists
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.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, and only replacement fixes it.
How the visit works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on the number of rooms, including the tidy-up. In Rainham, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Move anything stored near the joints
- Tell us about any water getting in
- Tell us if parking is tricky

Quotes for commercial sealant in Rainham
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Any working-time requirements on site
- Access and height
- How many areas need sealing
- Whether there’s mould to deal with
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
Helping us quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Roughly how big the job is
- What’s wrong with the joints now
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
