Washroom sealing for Peaslake sites

Keeping Peaslake washrooms open while we work

Peaslake lies roughly 26 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

On a healthcare site such as St. Luke’s Hospital (5.8 miles north-west of Peaslake), washroom work starts with the infection-control team’s sign-off. Where you’re responsible for a hall attached to a building such as Church of St Mark, its kitchen and toilets need sealant that stays cleanable. Hotels such as Hurtwood Hotel, less than half a mile to the south-west of Peaslake, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Peaslake is about 6 miles south-west of Dorking, in Surrey. Anywhere in GU5, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Peaslake is one of 379 places in Surrey on our list. Sites around London have their own page, roughly 26 miles from Peaslake.

We take on washrooms and wet areas across the GU5 postcode area, whatever the building. Buildings on Pond Lane, Peaslake Lane and Walking Bottom are within our area for washrooms and wet areas. Close to Peaslake, our area also takes in Holmbury St Mary (1 mile east), Farley Green (2 miles west), Pitland Street (2 miles east), Ewhurst (3 miles south) and Ewhurst Green (3 miles south). Further afield, our area takes in Guildford (7 miles north-west), Woking (10 miles north-west), Epsom (12 miles north-east), Horley (12 miles east), Redhill (12 miles east) and Farnham (15 miles west).

About our washroom sealing in Peaslake

In a busy washroom, the sealant normally gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. If you have complaints from staff, guests or users about tired washrooms and failed joints along IPS and cubicle panels, we can put it right, on urinals and WCs, kitchens and tea points and vanity units and basins alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Peaslake is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Halls and community buildings near places like Peaslake 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.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What affects the price in Peaslake

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The total length or number of joints
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Your programme or deadline
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours
  • The type of building and who uses it

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or email the details over.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Keep a record of which washrooms need attention
  • Clean sealant with gentle products and a soft cloth
  • Share your site rules when you send details
  • Include joints in routine washroom inspections

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

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

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Questions about Peaslake

Is a hospital such as St. Luke’s Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

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

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

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Is it possible to just clean mouldy silicone?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

What guarantee comes with washroom resealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Commercial clients in Peaslake

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • A room that stays damp because ventilation isn’t working
  • Water escaping beneath the floor rather than through a joint
  • Vanity carcasses that have swollen

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

Joints and surfaces we work on

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

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Peaslake can be grouped with others nearby. You will have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Point out any areas we must not close
  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
