Washroom sealing across Peckham

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How the job changes by surface

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we will say if the trouble looks to be beneath the floor.

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.

About our washroom sealing in Peckham

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 staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we will plan around them. We work on vanity units and basins, kitchens and tea points and urinals and WCs, and what we are called in for most is a new bead over an old one coming away and shower tray joints that have opened up. A specialist sealant contractor works differently from a general builder: in Peckham, that means joint design, primers and backing rod as standard.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Commercial washrooms in Peckham

Two care or nursing homes sit less than 2 miles from Peckham. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home. The area within 2 miles of Peckham holds a good number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Toilets at colleges like Christ the King: Aquinas Sixth Form College (to the east of Peckham) take heavy use from students and staff alike. Healthcare estates like Maudsley Hospital, 1.2 miles to the west of Peckham, expect contractors to follow their permits and cleaning rules in every washroom.

Peckham is about 2 miles south-east of London, in Greater London. Businesses, contractors and managing agents in Peckham can call on us for washrooms and wet areas, as part of our coverage of Greater London. Our Greater London coverage takes in 764 places, large and small.

We take on washrooms and wet areas across the SE15, SE14 and SE5 postcode area. Buildings on Rye Lane, Relf Road and Mona Road are within our area.

FAQs: Peckham

Does a hotel in Peckham need to shut while its sealant is renewed?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Can you clean the mould off instead of resealing?

Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or use the quote form.

Advice

Signs you need washroom sealing in Peckham

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.

Things that typically lead to an enquiry:

  • Users noticing mouldy joints
  • Stained or open joints at kitchen sinks and worktops
  • Stained sealant around pans and urinals
  • Gaps where vanity tops meet the wall

For centre management at a site such as Cantium Retail Park (0.9 miles north of Peckham), washroom work is planned around footfall.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • What the guarantee covers, and for how long
  • Their public liability cover
  • Can the work be phased to keep areas open?

Our contractor checklist

Quoting for work in Peckham

A fixed quote reflects the actual work. It allows for:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • How much there is to seal
  • The size and state of each joint

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Before you send an enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • The asbestos register, for older buildings
  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around

For a fixed quote, call the office on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

Commercial clients in Peckham

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Avoid scourers and harsh descalers on silicone
  • Clear standing water from shower floors where possible
  • Share your site rules when you send details
  • Make sure washroom ventilation is running

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
