About our washroom sealing in Furnace Wood

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. We work on kitchens and tea points, vanity units and basins and accessible toilets and changing rooms, and the usual reasons a site gets in touch are failed joints along IPS and cubicle panels and stained or open joints at kitchen sinks and worktops. One point of contact handles commercial sealant work in Furnace Wood from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In and around smaller places like Furnace Wood, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.

A 12-month guarantee applies to all our work in West Sussex. Should something we installed fail, ring 01277 525 020 or email us and we’ll come back to it.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • Which sealant the job calls for

We don’t publish prices, since every building and every scope is different. Call for a quote.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • The postcode of the building
  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • Whether an asbestos survey exists

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Furnace Wood may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Point out any areas we must not close
  • Let building users know which areas are affected
  • Let us know about inductions and permits

Why it’s worth doing now in Furnace Wood

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Halls, stores and units around places like Furnace Wood may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why choose Mastic Doctor in Furnace Wood

  • Failed material removed, not covered up
  • Workmanship guaranteed for 12 months
  • A range of standard colours, depending on the product
  • A Constructionline member, so easy to vet

Aftercare for building managers

To get the most from the new sealant:

  • Photograph and log failed joints across the estate
  • Leave signs up until the cure time is over
  • Keep extract fans working and vents clear
  • Don’t leave trays and floors sitting wet

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

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

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Panel boards already damaged by water
  • Condensation from failed extract fans
  • Loose panels, vanity units or tiles, which need fixing first

If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think.

What we seal

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

Questions about Furnace Wood

Does a hotel in Furnace Wood need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Would you work within a site like Queen Victoria Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you phase washroom resealing?

Only the area we are working in is closed. Rooms go back into use once the sealant has cured and we start the next.

How long before the toilets can reopen?

Cure times vary by product and temperature. Each room gets its own reopening time from us, and signs stay up until then.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Can you follow the specification on our project?

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.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
