Washroom sealing in New Hinksey

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Washroom sealing for commercial buildings in New Hinksey

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. If you have shower tray joints that have opened up and mould spotting along silicone joints, we can help. One point of contact handles commercial sealant work in New Hinksey from the first photographs to the final walk-round, whether it’s one building or several.

A place of New Hinksey’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

New Hinksey: questions and answers

Can work in a care setting near New Hinksey go ahead while residents are there?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

Can you work around term dates at a campus such as University College?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

How do I request a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

How long does a job like this take?

It depends on the scope, but the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Leave it or put it right?

A tired washroom says a lot about how a building is run. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in New Hinksey is a clear list of what needs doing. A fixed quote follows.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Before we start on site

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

When something else is needed

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

  • A room that stays damp because ventilation isn’t working
  • Fittings that move too much to hold a bead
  • Vanity carcasses that have swollen

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Different surfaces, different methods

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and make the room look neglected.

Healthcare and care settings

We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we will confirm with the quote.

After the work

After handover, a little attention goes a long way:

  • Keep washrooms out of use until we say the sealant has cured
  • Inspect washroom sealant regularly
  • Make sure washroom ventilation is running
  • Report split joints at trays and basins early

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
