Washroom sealing for commercial buildings in Midhurst

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. If you have discoloured joints around urinals and WC pans and resealing that didn’t last because the old bead stayed, we can put it right, whatever the surface. Most enquiries from Midhurst 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.

Pub and restaurant kitchens around smaller places like Midhurst work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Why act early in Midhurst

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. In a smaller place such as Midhurst, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • Over 20 years of commercial sealing
  • One phone line for London, the South East and Scotland
  • Standard and matched colours in many product ranges
  • Fully insured, including public liability cover

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Leaks through tanking or membranes below the finishes
  • A dripping waste or valve behind a panel
  • Vanity carcasses that have swollen

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.

What we seal

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

How a job runs

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 typically taking half a day to a day per washroom, depending on the number of fittings. If neighbouring businesses or buildings around Midhurst need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Before we start on site

  • Send your site hours and access windows
  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings

Commercial clients in Midhurst

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Cost factors for washrooms and wet areas

Before we quote, we look at:

  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • Access and working height
  • How much existing material needs removing

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • The product your specification calls for
  • Your programme or deadline

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, ring 01277 525 020 or send details through our quote form.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

FAQs: Midhurst

Will our hotel in Midhurst need to close for the work?

Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.

Do you take on work at healthcare sites like Midhurst Community Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you hold CHAS accreditation?

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

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Which silicone is right for commercial washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Commercial washrooms in Midhurst

Midhurst has a number of hotels close by, all within 2 miles. 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. Midhurst lies roughly 45 miles out from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

At a hospital like Midhurst Community Hospital, 0.8 miles north-east of Midhurst, patient and staff washrooms are best done in short phases agreed with the ward. For a hall at a building such as Roman Catholic Church of Divine Motherhood, resealing the kitchen and toilets can be fitted between bookings.
