Washroom sealing across Silver Street

Washroom sealing in Silver Street

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Site teams most often ask us about black mould inside silicone joints that cleaning can’t shift and complaints from staff, guests or users about tired washrooms, across urinals and WCs, IPS panels and cubicles and showers, trays and wet room floors. A single leaking joint is often how a building in Silver Street first comes to us: we look at the rest while we’re there and tell you what we find.

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

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Busy facilities in and around Silver Street

Silver Street is about 36 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

Healthcare estates like Sittingbourne Memorial Hospital (2.5 miles north-east of Silver Street) expect contractors to follow their permits and cleaning rules in every washroom. For a hall at a building such as Church of St John the Baptist, resealing the kitchen and toilets can be fitted between bookings. For buildings on a site such as Kent Science Park, 1.4 miles east of Silver Street, washrooms and tea points can be resealed in phases through the working week.

Silver Street is about 3 miles south-west of Sittingbourne, in Kent. Our applicators travel to Silver Street for work on washrooms and wet areas. Our Kent coverage takes in 931 places, large and small. London is covered too, around 36 miles from Silver Street.

Anyone looking for washroom sealing in ME9 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Your questions answered

Will you plan work around the academic year at somewhere like Canterbury Christ Church University?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Would you work within a site like Sittingbourne Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Are you fully insured?

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

Can you reseal washrooms in healthcare buildings?

We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

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. If others near Silver Street need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  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.

What we need from you

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open

How the job changes by surface

Showers and trays

A tray that rocks or has cracked won’t be fixed by sealant, and we’ll say so before resealing.

Basins and vanity tops

Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.

How the quote is worked out

Before we quote, we look at:

  • How much existing material needs removing
  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Travel to remote or island sites

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What to include in your enquiry

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

  • Anything awkward about access or site hours
  • Whether an asbestos survey exists
  • Your programme or deadline
  • What the building is and how it’s used

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, phone 01277 525 020 or send details through our quote form.

After the work

Once the work is signed off, these steps help:

  • Keep a record of which washrooms need attention
  • Tell us about infection-control or permit rules before we quote
  • Keep washrooms out of use until we say the sealant has cured
  • Add sealant joints to planned maintenance checks

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Why deal with it now?

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. Older rural buildings around Silver Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Why appoint us

  • Colour agreed before work starts
  • CSCS-carded applicators
  • Workmanship guaranteed for 12 months
  • Failed material removed, not covered up
