Need washroom sealing in Martin?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Leave it or put it right?

Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and your cleaning team stops chasing it. For buildings around smaller places like Martin, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

There’s no price list, since every building and every scope is different. Call for a quote.

Why appoint us

  • Over 20 years of commercial sealing
  • Standard and matched colours in many product ranges
  • Fixed quotes based on photographs, drawings or a visit
  • Public liability insurance in place

Washroom sealing in Martin

From one staff toilet in Martin to washrooms across a whole estate, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. If you have split or peeling sealant at shower trays and kitchen worktop joints that can’t be kept clean, we can help, on accessible toilets and changing rooms, vanity units and basins and urinals and WCs alike. Searching for sealant specialists in Martin? We have been sealing commercial buildings since 2005.

Smaller places such as Martin 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Keep extract fans working and vents clear
  • Don’t leave trays and floors sitting wet
  • Clean sealant with gentle products and a soft cloth
  • Leave signs up until the cure time is over

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

When to call us in Martin

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.

Typical triggers for a call:

  • Complaints from staff, guests or users about tired washrooms
  • Open joints at the base of cubicle panels
  • Kitchen worktop joints that can’t be kept clean
  • Black mould inside silicone joints that cleaning can’t shift

Around Martin, washroom joints are resealed by removing the old silicone completely and laying anti-mould sanitary silicone on dry surfaces.

How to choose a sealant contractor

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Martin may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  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.

Getting the site ready

  • Agree which areas must stay open
  • Flag any permit to work we’ll need
  • Warn occupants and staff about the work

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Washroom sealing around Martin: how the place shapes the job

Church halls and community buildings, such as those at Church of All Saints, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Martin is in Hampshire. Martin sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Martin is one of 723 places in Hampshire on our list for washrooms and wet areas. For work in that direction, see our Southampton page.

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Different surfaces, different methods

Urinals and WC pans

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

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

Common questions from Martin clients

What documents will you need to give us for a job in Martin?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Martin too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

What’s the quickest route to 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.

Can washrooms stay open while you work?

The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.
