Washroom sealing in Ascott-under-Wychwood, done properly

For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we will confirm with the quote. The enquiries we see most involve failed sealant in a tea point or staff kitchen and users noticing mouldy joints, on vanity units and basins, kitchens and tea points and showers, trays and wet room floors. Most enquiries from Ascott-under-Wychwood start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Smaller places such as Ascott-under-Wychwood 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.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we’re called out for in Ascott-under-Wychwood

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.

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

  • Mould spotting along silicone joints
  • Stained sealant around pans and urinals
  • Open joints along basins and vanity units
  • Split or peeling sealant at shower trays

Hotels such as Shaven Crown Hotel, 1.5 miles to the west of Ascott-under-Wychwood, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards

Choosing a commercial sealant contractor

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Ascott-under-Wychwood need work, visits can be combined. A fixed quote is given before anything starts.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Advice

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Why it’s worth doing now in Ascott-under-Wychwood

A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. For buildings around smaller places like Ascott-under-Wychwood, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Common questions from Ascott-under-Wychwood clients

Will the toilets in our Ascott-under-Wychwood building be out of use?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Will our hotel in Ascott-under-Wychwood need to close for the work?

In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Can you clean the mould off instead of resealing?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you have public liability insurance?

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

How long before the toilets can reopen?

Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.

Surface by surface

Kitchens and tea points

Kitchen work can be phased around service. Your site hours and access windows set the timing.

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.

When it isn’t the sealant

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

  • Water from plumbing, not from a joint
  • Swollen or delaminated boards behind panels or vanity tops
  • Leaks through tanking or membranes below the finishes

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.
