Washroom sealing across Hollywater

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

Washroom sealing in Hollywater

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. If you are dealing with washrooms that look worn because of the sealant and urinal joints that look unhygienic, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hollywater, that means joint design, primers and backing rod as standard.

Community buildings around smaller places like Hollywater have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job we finish is backed by a 12-month workmanship guarantee, in Hollywater as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What affects the price in Hollywater

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

  • The product specified
  • The total length or number of joints
  • Site requirements such as inductions and permits
  • Phasing around occupants

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Your programme or deadline
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • Whether an asbestos survey exists

For a fixed quote, phone 01277 525 020 or email us. You can also send details through our quote form.

After the work

Once the work is signed off, these steps help:

  • Include joints in routine washroom inspections
  • Photograph and log failed joints across the estate
  • Brief cleaning staff to treat joints gently
  • Keep washrooms out of use until we say the sealant has cured

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

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

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A dripping waste or valve behind a panel
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Fittings that move too much to hold a bead

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Where we work in Hollywater

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

Surface by surface

Showers and trays

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

Basins and vanity tops

Vanity tops and basins are splashed all day, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.

Toilets, showers and kitchens around Hollywater

At about 43 miles from central London, Hollywater is within reach of the capital, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, which is why the work is phased.

Church halls and community buildings, such as those at St Mark's Sacred Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Schools such as Woodlea Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Hollywater is about 6 miles south-east of Alton, in Hampshire. Our applicators travel to Hollywater for work on washrooms and wet areas, handled exactly as we handle every other area. We work across 723 places in Hampshire, large and small. Our Portsmouth page has more on work in that area.

Common problems we fix in Hollywater

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Typical triggers for a call:

  • Failed sealant in a tea point or staff kitchen
  • A new bead over an old one coming away
  • Urinal joints that look unhygienic
  • Gaps where vanity tops meet the wall

On an industrial estate such as Woolmer Trading Estate (0.8 miles north-west of Hollywater), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Questions to ask before you book

  • Their public liability cover
  • How they’ll work around occupants
  • How the joint faces will be prepared and primed
  • Whether their applicators hold CSCS cards

Our contractor checklist

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking half a day to a day per washroom, depending on the number of fittings. Jobs in and around smaller places like Hollywater are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Have the specification and drawings to hand
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Hollywater: questions and answers

Must every washroom in our Hollywater building shut while you work?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Is a hospital such as Chase Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is old silicone taken out first?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

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.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.

Are you insured?

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

Will you quote for a small job?
