Washroom sealing in Norwood New Town

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

What we’re called out for in Norwood New Town

Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

Things that usually lead to an enquiry:

  • Washrooms that look worn because of the sealant
  • Kitchen worktop joints that can’t be kept clean
  • Sealant laid over old silicone and now peeling
  • Urinal joints that look unhygienic

Customer toilets in retail centres such as Bell Green Retail Park (2.7 miles east of Norwood New Town) rarely close, so resealing is phased.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

How we handle washroom sealing in Norwood New Town

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. If you have stained sealant around pans and urinals and panel joints letting water behind, we can put it right. A specialist sealant contractor works differently from a general builder: in Norwood New Town, that means joint design, primers and backing rod as standard.

Washrooms in London offices, hotels and gyms are used hard from morning to evening. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a job in Norwood New Town, access comes first. Give us the hours we can be on site and we will schedule to suit.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Commercial washrooms in Norwood New Town

Norwood New Town has several hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available. Norwood New Town has six care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

At a hospital like British Home & Hospital for Incurables, 0.7 miles west of Norwood New Town, patient and staff washrooms are best done in short phases agreed with the ward. Units at estates like Hamilton Road Industrial Estate (to the north of Norwood New Town) have welfare blocks whose showers and toilets see shift after shift.

For managing agents and facilities managers

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

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

After the work

Once the work is signed off, a little attention goes a long way:

  • Inspect washroom sealant regularly
  • Share your site rules when you send details
  • Clear standing water from shower floors where possible
  • Report faulty extraction promptly

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

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

Questions about Norwood New Town

Must a hotel around Norwood New Town close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is there a guarantee on the work?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Surface by surface

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.

Honest limits

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

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.
