Washroom sealing in Fair Oak

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Maintenance after handover

For the best life from the joints:

  • Respect the cure time before reopening each room
  • Keep a record of which washrooms need attention
  • Clear standing water from shower floors where possible
  • Include joints in routine washroom inspections

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.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Washroom sealing in Fair Oak

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you’re dealing with resealing that didn’t last because the old bead stayed and open joints at the base of cubicle panels, we can put it right, on showers, trays and wet room floors, kitchens and tea points and accessible toilets and changing rooms alike. Most enquiries from Fair Oak start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

In and around smaller places like Fair Oak, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, phone 01277 525 020 or email us and we’ll arrange a return visit.

How the job changes by surface

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed as well as site permits.

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant, so the product is chosen to suit.

How the quote is worked out

Before we quote, we look at:

  • How much there is to seal
  • The size and state of each joint
  • The product specified
  • How much existing material needs removing

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Clear photographs of the problem areas

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send photos by email.

Wet areas in Fair Oak’s workplaces

Fair Oak lies roughly 49 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

For buildings on a site such as Scion Business Park (1.5 miles north-east of Fair Oak), washrooms and tea points can be resealed in phases through the working week. Church halls and community buildings, such as those at Church of St Paul, have kitchens and toilets used by many groups, and their sanitary sealant works hard. For a site such as West Berkshire Community Hospital, 5.5 miles to the north-west of Fair Oak, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Fair Oak is about 3 miles west of Tadley, in Hampshire. We cover commercial sites throughout Fair Oak. We work across 723 places in Hampshire, from busy centres to rural villages. Our Reading page has more on work in that area (12 miles or so).

Sites close to Fair Oak are covered too, including Ashford Hill (1 mile north), Plastow Green (1 mile west), Wolverton (1 mile south), Goose Hill (1 mile north-west) and Hyde End (2 miles north).

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Fair Oak, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open

Common questions from Fair Oak clients

Is Fair Oak too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

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

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

What sealant do you use in washrooms?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

Is colour matching possible?

It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

How long before the toilets can reopen?

The silicone needs time to cure before water reaches it. We plan the phasing around that so there are always rooms open.

Can you handle several sites?

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

Building owners, agents and FMs in Fair Oak

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Fittings that move too much to hold a bead
  • Leaks through tanking or membranes below the finishes
  • Panel boards already damaged by water

Not sure which it is? You can call 01277 525 020 or email the details over and we will tell you honestly before you book.
