How we handle commercial sealant in Thornton Heath

For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. We can quote for several properties at once. If you’re dealing with whole floors of tired en suites and black, stained silicone in guest bathrooms, we can help, on hotel bathrooms, rental portfolios and student & care accommodation alike.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Where a building in Thornton Heath needs to stay open, work can be planned outside normal hours.

A one-year guarantee comes as standard, so you are covered after we have gone.

Work for landlords, hotels and businesses

We also work for property managers and facilities teams. We can quote a run of properties together.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

What sealant work cannot fix

New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant won’t put right:

  • Certifying fire stopping or building compliance
  • Water coming from plumbing rather than sealant
  • Damaged sanitaryware that needs replacing

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Thornton Heath: your questions answered

Can you do commercial sealant in Thornton Heath?

Yes. We work across London and the South East, and Thornton Heath is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Thornton Heath station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.

Can you supply method statements and risk assessments?

We are fully insured, so start by telling us what your site asks for. Send over your requirements and we will confirm what we can provide.

Are you ARBOMaster approved?

Yes. We’re an ARBOMaster approved applicator.

Can you work outside opening hours?

Often, yes. Let us know when the building is quietest, and we’ll see what can be arranged.

Do you take out the old sealant first?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

How long will you be here?

It depends on the size of the job, but most jobs take as long as the scope needs, from one welfare room to a full building. We’ll tell you when we quote.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

What affects the cost of commercial sealant

The quote reflects the job in front of us. We look at:

  • Working hours on commercial sites
  • The number and length of the joints
  • How much old sealant there is and how hard it is to remove
  • The product the joint needs

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What we need to know

To make quoting easier, let us know:

  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
  • Where the property is
  • If someone has resealed it before

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

What commercial sealant looks like in Thornton Heath

London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.

If you look after a church, hall or community building such as Church of St Stephen, halls and community kitchens see heavy use, and their sealant shows it. For landlords with property near Thornton Heath station, we can quote for one property or a whole portfolio of rentals. For site and facilities teams at buildings such as Winterbourne Junior Girls' School, washroom and kitchen sealant can be programmed around term times or opening hours.

Aftercare tips

Looking after new joints is easy, and it makes a real difference:

  • Leave squeegees in busy showers
  • Use mild cleaners on sealant, not bleach or abrasives
  • Include the silicone on your room checklists
  • Keep a record of which rooms were resealed and when

Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.

Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.

How it works

We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours per area, with larger sites planned over several visits. In Thornton Heath, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Each finished area is checked with you and given a cure time.

Before we arrive

  • Mention any parking rules near the property
  • Keep children and pets away from the work area
  • Tell us about any water getting in

Leave it or put it right?

Guests and staff judge a building by its bathrooms. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing will not fix it. New sealant does. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Thornton Heath, the repair is bigger than a sealant job.

What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
