Washroom sealing for Holyport sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle washroom sealing in Holyport

Accessible WCs, showers and changing areas have their own pinch points: 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 they get particular attention. If you’re dealing with users noticing mouldy joints and sealant lifting along a tray edge, we can put it right, on urinals and WCs, showers, trays and wet room floors and accessible toilets and changing rooms alike. Facilities teams, main contractors and managing agents in Holyport tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Halls and community buildings near places like Holyport are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. Smaller jobs around Holyport can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First, the phasing is agreed so facilities stay open.
  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.

What we need from you

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Send your site hours and access windows

How the job changes by surface

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. We check fixings before sealing.

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Food-safe sealants are used where food may touch the joint.

What sets the cost

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

  • How much there is to seal
  • Access and working height
  • Location, for remote and island sites
  • Site requirements such as inductions and permits

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas
  • Anything awkward about access or site hours
  • The product your specification calls for

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Fittings that move too much to hold a bead
  • Swollen or delaminated boards behind panels or vanity tops
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer before you book.

Where we work in Holyport

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

Aftercare for building managers

For the best life from the joints:

  • Leave signs up until the cure time is over
  • Share your site rules when you send details
  • Make sure washroom ventilation is running
  • Act on the first split you see at a shower tray

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

Mouldy sealant only gets harder to ignore and users notice. Replacing it early keeps the job to a reseal.

Your questions answered

Is Holyport too small for you to travel to?

No. Places such as Holyport are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will our hotel in Holyport need to close for the work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

How many days will you need on site?

That varies with the scale of the job, but the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Can you quote from photographs?

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

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
