Your questions answered

Will the toilets in our Dunsfold building be out of use?

Typically only some of them, for a short time. We work in phases so other facilities stay open. We’ll tell you the curing time for the product before we start.

Is a smaller place like Dunsfold outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Is old silicone taken out first?

The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

After the work

After handover, these steps help:

  • Make sure washroom ventilation is running
  • Photograph and log failed joints across the estate
  • Don’t leave trays and floors sitting wet
  • Include joints in routine washroom inspections

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Why act early in Dunsfold

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Halls, stores and units around places like Dunsfold may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Dunsfold need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Warn occupants and staff about the work
  • Agree which areas must stay open

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Hollow tiles or loose panels behind the joint
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Leaks through tanking or membranes below the finishes

If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

  • Showers, trays and wet room floors
  • IPS panels and cubicles
  • Urinals and WCs
  • Vanity units and basins
  • Accessible toilets and changing rooms
  • Kitchens and tea points

Do you need washroom sealing in Dunsfold?

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.

Most enquiries start with something like this:

  • Failed sealant behind washroom basins
  • Failed joints along IPS and cubicle panels
  • Washrooms that look worn because of the sealant
  • Kitchen worktop joints that can’t be kept clean

Where you are responsible for a hall attached to a building such as Church of St Mary and All Saints, its kitchen and toilets need sealant that stays cleanable.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • Do they follow the manufacturer’s priming guidance?
  • Their public liability cover
  • How they handle RAMS and site documents
