Washroom sealing in Wherwell Wood, done properly

You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. We work on showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and the usual reasons a site gets in touch are split or peeling sealant at shower trays and sealant laid over old silicone and now peeling. Searching for sealant specialists in Wherwell Wood? We’ve been sealing commercial buildings since 2005.

Halls and community buildings near places like Wherwell Wood 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

After the work

After handover, a little attention goes a long way:

  • Don’t leave trays and floors sitting wet
  • Keep washrooms out of use until we say the sealant has cured
  • Avoid scourers and harsh descalers on silicone
  • Note failing joints building by building

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Keeping Wherwell Wood washrooms open while we work

At about 63 miles from central London, Wherwell Wood is within reach of the capital. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.

On an industrial estate such as Harewood Forest Industrial Estate, 2.2 miles to the east of Wherwell Wood, staff toilets, showers and canteens are where sanitary sealant takes the most wear. Staff changing rooms and patient toilets at places like Andover War Memorial Hospital (to the north-west of Wherwell Wood) need cleanable, sound silicone.

Wherwell Wood is about 3 miles south-east of Andover, in Hampshire. Across the SP11 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Our Southampton page has more on work in that area, about 18 miles away.

We take on washrooms and wet areas across the SP11 postcode area, for business premises of every kind. Just outside Wherwell Wood, we also work in Wherwell (1 mile south-east), Goodworth Clatford (1 mile west), Cottonworth (1 mile south), Fullerton (2 miles south) and Chilbolton (2 miles south-east).

What the job involves on each surface

Healthcare and care settings

In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements as well as site permits.

IPS and cubicle panels

Panels flex slightly in use so the bead needs to cope with it. We check fixings before sealing.

Common questions from Wherwell Wood clients

Can you work around term dates at a campus such as Andover College?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is a hospital such as Andover War Memorial Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Can one quote cover more than one building?

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

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you offer coloured sealant?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Is old silicone taken out first?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

When to call us in Wherwell Wood

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

These are often picked up first by site or facilities staff:

  • Discoloured joints around urinals and WC pans
  • Black mould inside silicone joints that cleaning can’t shift
  • Panel joints letting water behind
  • Shower tray joints that have opened up

For centre management at a site such as Churchill Retail Park, 2.9 miles north of Wherwell Wood, washroom work is planned around footfall.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Their public liability cover
  • Can the work be phased to keep areas open?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

Cost factors for washrooms and wet areas

We price every job individually. The things that drive the figure:

  • Access and working height
  • How much existing material needs removing
  • The product specified
  • The size and state of each joint

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • What the building is and how it’s used
  • Anything awkward about access or site hours

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call 01277 525 020 or email a schedule or drawings.
