Washroom sealing for Highsted sites

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

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Highsted can form part of a wider programme across Kent.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Washroom sealing in Highsted

From one staff toilet in Highsted to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. If you are dealing with urinal joints that look unhygienic and washrooms that look worn because of the sealant, we can help, on vanity units and basins, showers, trays and wet room floors and IPS panels and cubicles alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Highsted it comes down to the same thing: the right product in a properly prepared joint.

Halls and community buildings near places like Highsted are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How a job runs

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Highsted need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Before we start on site

  • Flag any permit to work we’ll need
  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected

Ask for a quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or send photos by email.

Advice

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Add sealant joints to planned maintenance checks
  • Don’t leave trays and floors sitting wet
  • Note failing joints building by building
  • Make sure washroom ventilation is running

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.

What affects the price in Highsted

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

  • Access and working height
  • Location, for remote and island sites
  • Phasing around occupants
  • The total length or number of joints

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Photos of the joints, close up and from further back
  • Any dates the work must fit around

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email the details over if you’d rather talk the job through.

Keeping Highsted washrooms open while we work

Highsted has several hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping. Highsted lies roughly 38 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

At a college such as Sittingbourne College, 1.5 miles north-west of Highsted, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Hotels such as The George Hotel (to the north of Highsted) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Highsted is about 2 miles south of Sittingbourne, in Kent. Highsted sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 931 places in Kent, large and small. London is covered too, around 38 miles from Highsted.

Business premises anywhere in ME9 are within our area. For a building on Stockers Hill and Highsted Road or nearby, we can quote for washrooms and wet areas. If your building is just outside Highsted, we cover Rodmersham Green (1 mile east), Rodmersham (1 mile east), Tunstall (1 mile west), Bapchild (1 mile east) and Dungate (1 mile south). A short drive away, we cover Maidstone (10 miles west), Ashford (13 miles south-east), Canterbury (15 miles east), Whitstable (13 miles east), Faversham (6 miles east) and Minster (7 miles north).

Landmarks near Highsted

Signs you need washroom sealing in Highsted

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.

Most enquiries start with something like this:

  • Resealing that didn’t last because the old bead stayed
  • Open joints at the base of cubicle panels
  • Sealant stained black around basins and showers
  • Failed sealant behind washroom basins

Clinical washrooms at sites like Sittingbourne Memorial Hospital (1.1 miles north of Highsted) are scheduled with the ward so the room is out of use for as little time as possible.

What to look for in a quote

  • Who will actually carry out the work
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?
  • How joint depth will be controlled

Questions to ask before you appoint anyone

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Questions about Highsted

Can you work on a hospital site such as 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 Highsted too far out for you?

Not at all. Highsted is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Are you fully insured?

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

Can you clean the mould off instead of resealing?

Normally not. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

How many days will you need on site?

That varies with the scale of the job, but the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.
