About our washroom sealing in Monxton

In a commercial washroom, sealant is usually the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, 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. If you have sealant stained black around basins and showers and sealant laid over old silicone and now peeling, we can put it right, whatever the surface. A single leaking joint is often how a building in Monxton first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Monxton still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Our workmanship is guaranteed for 12 months, in Monxton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why act early in Monxton

Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. Halls, stores and units around places like Monxton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

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.

Take a look at how commercial sealant jobs are priced and our accreditations and insurance.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. If others near Monxton need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Before we start on site

  • Send your site hours and access windows
  • Share the asbestos register for older buildings
  • Tell us what induction or permit system the site runs

Questions we are asked in Monxton

Is Monxton too far out for you?

No. Places such as Monxton are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Can you take on a job at a hospital such as Andover War Memorial Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you have public liability insurance?

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

What do you charge?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

How long before the toilets can reopen?

That varies with the sealant and the room temperature. You will get a reopening time for each area, and signs stay up until then.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Clear standing water from shower floors where possible
  • Include joints in routine washroom inspections
  • Photograph and log failed joints across the estate
  • Act on the first split you see at a shower tray

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

Building owners, agents and FMs in Monxton

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Monxton can sit alongside others in a wider programme across Hampshire.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What affects the price in Monxton

To price the job, we consider:

  • Site requirements such as inductions and permits
  • The product specified
  • How much existing material needs removing
  • Distance, for remote addresses

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Any specification or named product

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Hollow tiles or loose panels behind the joint
  • A dripping waste or valve behind a panel
  • Panel boards already damaged by water

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

Toilets, showers and kitchens around Monxton

At about 66 miles from central London, Monxton is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time.

For a school such as Amport Church of England Primary School, washroom and kitchen sealant can be renewed around term dates. On a healthcare site such as Andover War Memorial Hospital, 2.9 miles north-east of Monxton, washroom work starts with the infection-control team’s sign-off. Office washrooms on sites such as Plot 5 Andover Business Park (to the north-east of Monxton) are in use all working day, so resealing is phased to keep some open.
