Washroom sealing near Northmoor

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Your questions answered

Is Northmoor off your patch?

Not at all. Northmoor is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Could you schedule work at a campus like Azad University in Oxford for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Are you fully insured?

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

Do you do washroom sealing in healthcare settings?

We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

What will the job cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email a schedule or drawings.

Washroom sealing in Northmoor

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. If you have users noticing mouldy joints and discoloured joints around urinals and WC pans, we can help, on showers, trays and wet room floors, IPS panels and cubicles and vanity units and basins alike. Looking for mastic applicators who cover Northmoor? We’ve been sealing commercial buildings since 2005.

Halls and community buildings near places like Northmoor are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • The size and state of each joint
  • Quantities, in metres or numbers

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Specification clauses that apply
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

Building owners, agents and FMs in Northmoor

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Northmoor may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Leaks through tanking or membranes below the finishes
  • Water from plumbing, not from a joint
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

Surfaces we seal

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

Site staff or a sealant specialist?

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

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What we’re called out for in Northmoor

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Any of the following is a good reason to get the joints checked over:

  • Resealing that didn’t last because the old bead stayed
  • Stained or open joints at kitchen sinks and worktops
  • Sealant lifting along a tray edge
  • Open joints along basins and vanity units

Halls linked to places like Church of St Denys host groups all week, which is hard on kitchen and toilet sealant.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Their pre-qualification and accreditations
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area
