Common questions from Monkhams clients

Can you work in a care home near Monkhams with residents in?

Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.

Does a hotel in Monkhams need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

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.

How we handle washroom sealing in Monkhams

Whether it’s a single toilet block in Monkhams or a programme across several buildings, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. Site teams most often ask us about split or peeling sealant at shower trays and sealant stained black around basins and showers, across vanity units and basins, kitchens and tea points and showers, trays and wet room floors. Whoever orders the work in Monkhams, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.

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’re clear about what is covered before work starts.

When to call us in Monkhams

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water, and they stain, crack or wash out.

Things that typically lead to an enquiry:

  • Gaps where vanity tops meet the wall
  • Complaints from staff, guests or users about tired washrooms
  • Black mould inside silicone joints that cleaning can’t shift
  • Open joints at the base of cubicle panels

At a hospital like The Holly Private Hospital, which lies north-east of Monkhams, patient and staff washrooms are best done in short phases agreed with the ward.

What your quote should include

  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the existing material will be dealt with

How to choose a sealant contractor

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a job in Monkhams, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work
  • Tell us your opening times and when work is allowed

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Keep extract fans working and vents clear
  • Note failing joints building by building
  • Clean sealant with gentle products and a soft cloth
  • Don’t leave an open joint at a basin or tray

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Keeping Monkhams washrooms open while we work

12 care or nursing homes sit less than 2 miles from Monkhams. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. We plan the work with the manager so residents are disturbed as little as possible. Monkhams has a number of hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.

On an industrial estate such as Woodford Trading Estate, 1.9 miles south of Monkhams, staff toilets, showers and canteens are where sanitary sealant takes the most wear. At a university such as University of Portsmouth Walthamstow Campus (3 miles south-west of Monkhams), summer is the usual window for resealing residence bathrooms.

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • How accessible the joints are
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Distance, for remote addresses

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Details that help us quote

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

  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work

For a fixed quote, ring 01277 525 020 or send photos by email. Our quote form is another easy route.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Vanity carcasses that have swollen
  • Fittings that move too much to hold a bead

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

What we seal

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