Washroom sealing for Hollow Street sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Your questions answered

Is a hospital such as St Martins Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Is Hollow Street too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

What do you charge?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

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.

Washroom sealing for commercial buildings in Hollow Street

In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and what we’re called in for most is panel joints letting water behind and split or peeling sealant at shower trays. Most enquiries from Hollow Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Community buildings around smaller places like Hollow Street have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sets the cost

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • Removal of failed or old sealant
  • Access and working height
  • The total length or number of joints

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • Any specification or named product
  • The postcode of the building

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Hollow Street can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work

Advice

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Why act early in Hollow Street

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. Around Hollow Street, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Why clients in Hollow Street choose us

  • A fixed quote before work starts
  • Our applicators hold CSCS cards
  • Constructionline member for supplier checks
  • Coloured sealants to suit the setting, where available

What sealant work can’t fix

Honesty saves time and money. Fresh joints won’t solve:

  • Water from plumbing, not from a joint
  • Vanity carcasses that have swollen
  • Mould caused by poor ventilation, which will return until the extract is fixed

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

When to call us in Hollow Street

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

Look out for the following:

  • Urinal joints that look unhygienic
  • Gaps where vanity tops meet the wall
  • Washrooms that look worn because of the sealant
  • Kitchen worktop joints that can’t be kept clean

Pupil toilets at schools like Chislet Church of England Primary School take heavy daily use, and the holidays give the window to reseal.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?
  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
