Washroom sealing in Brook Street, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you’re dealing with discoloured joints around urinals and WC pans and sealant laid over old silicone and now peeling, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Brook Street, preparation and product choice get the time they need.

Smaller places such as Brook Street still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Work for main contractors and building owners

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

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Quoting for work in Brook Street

These are the things that shape the price:

  • Access and working height
  • Distance, for remote addresses
  • How much there is to seal
  • Phasing around occupants

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Any specification or named product
  • The asbestos register, for older buildings
  • A wide shot and a close-up of the area
  • The site address and postcode

To get a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings. You can also send details through our quote form.

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Busy facilities in and around Brook Street

A number of hotels sit less than 2 miles from Brook Street. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available. Brook Street is about 18 miles from central London. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Toilets at colleges like Havering Technical College (to the west of Brook Street) take heavy use from students and staff alike. Halls linked to places like Church of St Peter host groups all week, which is hard on kitchen and toilet sealant.

Do you need washroom sealing in Brook Street?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

Most enquiries start with something like this:

  • A new bead over an old one coming away
  • Panel joints letting water behind
  • Discoloured joints around urinals and WC pans
  • Black mould inside silicone joints that cleaning can’t shift

Office washrooms on sites such as Warley Hill Business Park (to the south-east of Brook Street) are in use all working day, so resealing is phased to keep some open.

Questions to ask before you book

  • What site paperwork they can supply
  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Leaks through tanking or membranes below the finishes
  • Water from plumbing, not from a joint

If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.

Brook Street: questions and answers

Do hotels near Brook Street have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.

Is a smaller place like Brook Street outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Will cleaning remove black mould from sealant?

Normally not. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Smaller jobs around Brook Street can be grouped with others nearby. 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. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  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.

Getting the site ready

  • Make sure the joints can be reached
  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand
