Washroom sealing near Stocks Green

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Cost factors for washrooms and wet areas

The price varies from site to site. Expect it to depend on:

  • How much existing material needs removing
  • Distance, for remote addresses
  • Backing rod, priming and other preparation
  • Phasing around occupants

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • The postcode of the building
  • The type of building and who uses it
  • The product your specification calls for
  • Rough lengths or quantities, or drawings if you have them

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call 01277 525 020 or use the quote form.

A few photographs and a count of fittings are enough for a quick quote, or we can arrange a visit. We work on accessible toilets and changing rooms, kitchens and tea points and IPS panels and cubicles, and what we’re called in for most is split or peeling sealant at shower trays and washrooms that look worn because of the sealant.

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

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

For a hall at a building such as Parish Church of St John, resealing the kitchen and toilets can be fitted between bookings. For a college such as West Kent College, 2.2 miles south-east of Stocks Green, half-term and summer give the windows for washroom work.

Signs you need washroom sealing in Stocks Green

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.

Site and facilities staff are often the first to spot these:

  • Urinal joints that look unhygienic
  • Washrooms that look worn because of the sealant
  • Resealing that didn’t last because the old bead stayed
  • Failed sealant behind washroom basins

For a school such as Hildenborough Church of England Primary School, washroom and kitchen sealant can be renewed around term dates.

Choosing a commercial sealant contractor

Why act early in Stocks Green

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Around Stocks Green, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

FAQs: Stocks Green

Is Stocks Green too small for you to travel to?

No. Places such as Stocks Green are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you plan work around the academic year at somewhere like University of Kent - Tonbridge?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so there are always rooms open.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Do you phase washroom resealing?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time, then we move on.

What the job involves on each surface

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we will say if the trouble looks to be beneath the floor.

Basins and vanity tops

Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Clear standing water from shower floors where possible
  • Note failing joints building by building
  • Add sealant joints to planned maintenance checks
  • Mention any site permits or estates rules at quote stage

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Mouldy sealant only gets harder to ignore and users notice. Replacing it early keeps the job to a reseal.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Stocks Green 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. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed
