Washroom sealing in Kemsley

In a commercial washroom, sealant is normally the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on IPS panels and cubicles, vanity units and basins and accessible toilets and changing rooms, and the failures we’re asked to look at most are failed sealant in a tea point or staff kitchen and discoloured joints around urinals and WC pans. Searching for sealant specialists in Kemsley? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

In and around places like Kemsley, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the quote is worked out

These are the things that shape the price:

  • The total length or number of joints
  • How accessible the joints are
  • Which sealant the job calls for
  • The size and state of each joint

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • The postcode of the building
  • 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 ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Washroom sealing around Kemsley: how the place shapes the job

Kemsley is within about 1 mile of the coast, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. Central London is about 37 miles from Kemsley, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

On a healthcare site such as Sittingbourne Memorial Hospital, 1.8 miles to the south of Kemsley, washroom work starts with the infection-control team’s sign-off. At a hotel such as The Bull Hotel, 1.4 miles south of Kemsley, the quieter weeks are the time to reseal bathrooms.

Kemsley is about 1 mile north of Sittingbourne, in Kent. Our applicators travel to Kemsley for work on washrooms and wet areas, handled exactly as we handle every other area. Our Kent coverage takes in 931 places, large and small. Sites around London have their own page, about 37 miles away.

Anyone looking for washroom sealing in ME10 and ME9 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on Court Road, Menin Road and Hurst Lane. We also cover Howt Green (1 mile west), Milton Regis (1 mile south-east), Sittingbourne (1 mile south), Iwade (1 mile north-west) and Murston (1 mile south) for washrooms and wet areas. Further afield, our area takes in Maidstone (11 miles south-west), Whitstable (13 miles east), Faversham (7 miles south-east), Minster (5 miles north-east), Davington (7 miles south-east) and Foley Park (10 miles south-west).

Local landmarks in Kemsley

Locally, jobs take us to sites close to Milton Creek Country Park, The Three Hats Inn and Borden Grammar School. Kemsley has its own railway station: Kemsley station. Other landmarks nearby include Castle Rough (0.6 miles east) and Court Hall Museum (0.8 miles south-west).

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. What matters most for a job in Kemsley is a clear list of what needs doing. You’ll then get a fixed price for the work.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  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. Joints are cleaned, degreased and dried before sealing.
  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.

Preparing the site

  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints
  • Flag any permit to work we will need

Advice

Kemsley: questions and answers

Will you plan work around the academic year at somewhere like KITE College?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Must a hotel around Kemsley close while you work?

In most cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we will plan around them.

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed 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.

Can you clean the mould off instead of resealing?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you reseal washrooms in healthcare buildings?

We do. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Building owners, agents and FMs in Kemsley

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

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Kemsley. Several sites can go on one quote, which keeps the paperwork simple.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

When something else is needed

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

  • Hollow tiles or loose panels behind the joint
  • A dripping waste or valve behind a panel
  • Condensation from failed extract fans

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.

Where we work in Kemsley

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

Signs you need washroom sealing in Kemsley

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

What tends to prompt an enquiry:

  • Resealing that didn’t last because the old bead stayed
  • Failed joints along IPS and cubicle panels
  • Washrooms that look worn because of the sealant
  • Stained or open joints at kitchen sinks and worktops

Toilets at colleges like KITE College, 1.1 miles south of Kemsley, take heavy use from students and staff alike.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid
