Surface by surface

Changing rooms and gyms

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray perimeters are a frequent source of leaks.

Washroom sealing for commercial buildings in Merton Abbey

For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we’ll confirm with the quote. We work on showers, trays and wet room floors, kitchens and tea points and vanity units and basins, and the failures we’re asked to look at most are panel joints letting water behind and failed sealant in a tea point or staff kitchen. Searching for sealant specialists in Merton Abbey? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

In a London area such as Merton Abbey, commercial washrooms in offices, hotels and leisure buildings see constant use. 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

FAQs: Merton Abbey

Could you schedule work at a campus like Kingston University Roehampton Vale Campus for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Will you work in a care home in Merton Abbey without moving residents out?

Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.

Do you work in Merton Abbey?

Yes. We cover Merton Abbey, and you can give us a call on 01277 525 020 or send photos by email to get started.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

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.

Sanitary sealant for Merton Abbey buildings

There are a good number of hotels within about 2 miles of Merton Abbey. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available. Three care or nursing homes sit less than 2 miles from Merton Abbey. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

Toilets at places like Priory Retail Park, under half a mile north of Merton Abbey, are cleaned constantly, which is hard on silicone. On a healthcare site such as St George's Hospital (1 mile north of Merton Abbey), washroom work starts with the infection-control team’s sign-off.

Do you need washroom sealing in Merton Abbey?

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.

It’s worth sending us details if you spot any of the following:

  • Open joints at the base of cubicle panels
  • Users noticing mouldy joints
  • Failed sealant in a tea point or staff kitchen
  • Sealant stained black around basins and showers

En suites at hotels like Antoinette Hotel, 0.8 miles north-west of Merton Abbey, are cleaned daily, which wears silicone over time.

Before you book anyone

  • How the existing material will be dealt with
  • What the guarantee covers, and for how long
  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. In Merton Abbey, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  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. Each area is handed back when ready.

What we need from you

  • Warn occupants and staff about the work
  • For older buildings, check the asbestos register before work
  • Clear stock, furniture or equipment away from the joints

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Fittings that move too much to hold a bead
  • Leaks through tanking or membranes below the finishes
  • A room that stays damp because ventilation isn’t working

If you are not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

Joints and surfaces we work on

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