Washroom sealing in Chalton

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on kitchens and tea points, IPS panels and cubicles and showers, trays and wet room floors, and the failures we are asked to look at most are open joints at the base of cubicle panels and shower tray joints that have opened up. Searching for sealant specialists in Chalton? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Community buildings around smaller places like Chalton 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.

Cost factors for washrooms and wet areas

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

  • The size and state of each joint
  • Any access equipment needed
  • Whether the work must be split into stages
  • How much there is to seal

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Before you send an enquiry

We can often quote from photos and a few details. Please tell us:

  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours
  • The product your specification calls for
  • Any dates the work must fit around

For a fixed quote, ring 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.

Wet areas in Chalton’s workplaces

At about 54 miles from central London, Chalton is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

On a healthcare site such as Petersfield Community Hospital (4.7 miles north of Chalton), washroom work starts with the infection-control team’s sign-off. Church halls and community buildings, such as those at Church of St Michael, have kitchens and toilets used by many groups, and their sanitary sealant works hard. If you manage an office at a site such as Enterprise Industrial Estate, which lies south-west of Chalton, the washrooms and tea points can be done a floor at a time.

Chalton is about 3 miles north-east of Horndean, in Hampshire. Chalton sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 723 places in Hampshire, from busy centres to rural villages. Sites around Portsmouth have their own page, about 10 miles away.

Business premises anywhere in PO8 are within our area for washrooms and wet areas. We also cover Blendworth (2 miles south-west), Buriton (3 miles north), Forestside (3 miles south-east), West Marden (3 miles south-east) and Weston (4 miles north) for washrooms and wet areas. A short drive away, we cover Gosport (12 miles south-west), Havant (5 miles south), Fareham (12 miles south-west), Horndean (3 miles south-west), Alton (15 miles north) and Hedge End (15 miles west).

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Chalton 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. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Have the specification and drawings to hand

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Questions we’re asked in Chalton

Is Chalton too small for you to travel to?

No. Places such as Chalton are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do we have to close all our washrooms in Chalton for resealing?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

Can the sealant be colour-matched?

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

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Why it’s worth doing now in Chalton

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Older rural buildings around Chalton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Panel boards already damaged by water
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Failed tanking beneath a wet-room floor or behind tiles

If in doubt, ring 01277 525 020 or email us and we’ll say what we think before you book.
