Washroom sealing in North Boarhunt

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

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around North Boarhunt, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints
  • For older buildings, check the asbestos register before work

Advice

Washroom sealing in North Boarhunt

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about resealing that didn’t last because the old bead stayed and kitchen worktop joints that can’t be kept clean, across urinals and WCs, showers, trays and wet room floors and accessible toilets and changing rooms. Whether you call it commercial sealant work, mastic application or joint sealing, in North Boarhunt it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for washrooms and wet areas

These are the things that shape the price:

  • Access and working height
  • Whether old sealant has to be cut out first
  • How much there is to seal
  • Phasing around occupants

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • Your programme or deadline

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or send details through our quote form.

Why act early in North Boarhunt

A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. Around North Boarhunt, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

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

  • Fixed quotes based on photographs, drawings or a visit
  • CHAS accredited
  • Our applicators hold CSCS cards
  • A Constructionline member, so easy to vet

Kitchens and tea points

Kitchen work can be phased around service. Your site hours and access windows set the timing.

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Do you need washroom sealing in North Boarhunt?

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

It’s worth sending us details if you spot any of the following:

  • Split or peeling sealant at shower trays
  • Sealant stained black around basins and showers
  • Stained or open joints at kitchen sinks and worktops
  • Gaps where vanity tops meet the wall

Pupil toilets at schools like Newtown Soberton Infant School take heavy daily use, and the holidays give the window to reseal.

Questions to ask before you appoint anyone

Doing it in-house

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.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Common questions from North Boarhunt clients

Is North Boarhunt off your patch?

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

Would you work within a site like Knowle Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Do you need to remove the old sealant?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
