Trusted commercial sealant in Downside

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

Commercial sealant in Downside, done properly

Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we will confirm what we can provide. Typical jobs include split sealant where wet room floors meet walls and large numbers of bathrooms needing the same work, on office washrooms & kitchens, student & care accommodation and rental portfolios.

If you have holiday lets, a converted barn used for business or a community building near Downside, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Whatever the size of the job, it’s backed by our one-year guarantee in Downside and across Surrey.

Common problems we fix in Downside

Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading. If a tray flexes, the sealant around it splits.

Keep an eye out for any of the following:

  • Joints that need doing before an inspection or audit
  • Leaks from showers into rooms or ceilings below
  • Whole floors of tired en suites
  • Sealant failing again soon after quick repairs

Community buildings like St Michael's Chapel are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

What your quote should include

  • How much experience the applicator has
  • What insurance they hold
  • What happens if the job turns out different
  • Whether they seal over old material or remove it

Our hiring checklist

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Different surfaces, different methods

Retail & leisure sites

Customer washrooms are part of the impression a business makes, and clean, neat sealant makes them look cared for.

Office washrooms & kitchens

Office washrooms and tea points are used all day, so the work can be arranged for quieter times. We reseal around basins, urinals, worktops and sinks.

Why act early in Downside

Before an inspection, audit or busy season, sealant is easy to overlook. Planning the work ahead means rooms are finished and cured in time, without a last-minute rush. Around Downside, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Why book with us

  • We agree the colour with you first
  • White, clear, grey or another colour, product permitting
  • Old sealant always removed completely
  • Sealant colour chosen to suit

Read how sealant jobs are priced and what customers say.

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Keep a record of which rooms were resealed and when
  • Plan resealing around quiet periods
  • Put a squeegee in each shower
  • Act on lifting sealant before it leaks

Include sealant in routine room inspections. A quick look at each bathroom when rooms are checked spots problems early.

It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.

The process

On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take as long as the scope needs, from one welfare room to a full building. Somewhere like Downside needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We walk the site with you and agree the rooms, the order and the hours.
  2. Every area is sheeted and the old silicone stripped out.
  3. We clean the joints, treat any mould and let them dry.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Each room is checked and handed back with its cure time.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Keep pets and children clear of the area while we work
  • Tell us about any previous sealing or DIY attempts
