How the visit works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a morning for a small washroom, and a planned programme for bigger sites. For a job in New Barn, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we visit and agree the scope, the sequence and the working hours.
- Each area is protected and the old sealant cut out completely.
- We clean the joints, treat any mould and let them dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.

New Barn: your questions answered
Can you do commercial sealant in New Barn?
Yes. We work across London and the South East, and New Barn is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Longfield station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
How do I get a quote for commercial sealant in New Barn?
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. You will get a clear quote before we start.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you supply method statements and risk assessments?
Let us know which documents your site needs, such as method statements, risk assessments or insurance details, and we will confirm what we can provide when we quote.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
How long does the job take?
Typically it takes as long as the scope needs, from one welfare room to a full building. Larger jobs naturally take longer, and we will say how long yours will take.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask cleaners to go gently on the silicone
- Log resealing so you know what’s due
- Report broken fans quickly
- Pass on the cure time to whoever cleans the rooms
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.
Signs to look for: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.
What affects the quote in New Barn
Call for a quick quote. What matters most is:
- Access and height
- The product the joint needs
- Working hours on commercial sites
- How many areas need sealing
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Helping us quote
To make quoting easier, please include:
- Where the property is
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

Commercial buildings in New Barn
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as Longfield Academy, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. If you look after a church, hall or community building such as Church of Saint Mary Magdalene, any kitchen and washrooms need the same sealant care as any other building.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens if it’s left?
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing won’t fix it. Replacing it does. In a smaller place like New Barn, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
