Washroom sealing in Cock Street

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. We work on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms, and the failures we are asked to look at most are washrooms that look worn because of the sealant and sealant laid over old silicone and now peeling. Searching for sealant specialists in Cock Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Common questions from Cock Street clients

Must a hotel around Cock Street close while you work?

In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Is a smaller place like Cock Street outside your area?

Not at all. Cock Street is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you clean the mould off instead of resealing?

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

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.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Why deal with it now?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Around Cock Street, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Toilets, showers and kitchens around Cock Street

Cock Street lies roughly 53 miles out from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available. The area within 2 miles of Cock Street holds a number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.

For a hall at a building such as St Matthew's Church, resealing the kitchen and toilets can be fitted between bookings. Clinical washrooms at sites like Severalls Hospital (5.3 miles south of Cock Street) are scheduled with the ward so the room is out of use for as little time as possible. En suites at hotels like Stoke by Nayland Hotel (0.6 miles north-east of Cock Street) are cleaned daily, which wears silicone over time.

When to bring in a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Cock Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

Advice

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Cock Street. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Different surfaces, different methods

Changing rooms and gyms

We phase work so not every changing area is closed at once. Phasing follows your site hours and access windows.

IPS and cubicle panels

Panels flex slightly in use so the bead needs to cope with it. We check fixings before sealing.

What affects the price in Cock Street

We price every job individually. The main factors are:

  • Distance, for remote addresses
  • Removal of failed or old sealant
  • The size and state of each joint
  • How accessible the joints are

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The product your specification calls for
  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Where the site is, with the postcode

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send photos by email with what you know.
