Commercial sealant in Bromley

In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. If you are dealing with joints that need doing before an inspection or audit and shower leaks reaching the floor below, we can put it right, on office washrooms & kitchens, retail & leisure sites and welfare facilities alike.

Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Bromley needs to stay open, work can be planned outside normal hours.

There’s a 12-month guarantee on every job.

Surface by surface

Hotel bathrooms

In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.

Welfare facilities

Failed sealant in welfare areas is a simple fix before an audit. Let us know when it needs to be done and we will schedule around it, cure time included.

What affects the quote in Bromley

Your quote is based on your job. We look at:

  • Mould in or behind the old joints
  • How many rooms, windows or areas are involved
  • The size of the job
  • When we can work, for business premises

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What to tell us for a quote

What to tell us when you ask for a quote:

  • Whether it has been sealed before
  • A few photos by email, if you can
  • Whether it’s a home or a business
  • What’s wrong with the joints now

There’s no standard price list, because every job is different. Instead, we send you a clear quote for your job. To arrange one, phone 0345 464 0079 or drop us an email.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Report broken fans quickly
  • Note the date each area was done
  • Include the silicone on your room checklists
  • Pass on the cure time to whoever cleans the rooms

A squeegee in each shower is a simple help: walls and trays dry faster, and so does the sealant.

Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, so the fix is replacement.

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take as long as the scope needs, from one welfare room to a full building. For a job in Bromley, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. The first visit is a look round the site to agree the scope.
  2. We agree when we will work, with early or out-of-hours slots where they can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Joints are dried, then resealed and tooled neatly.
  5. Housekeeping or site staff are told when each area can be used.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks
  • For indoor joints, keep the area dry beforehand if you can

Advice

Bromley: your questions answered

Do you work for hotels and guest houses in Bromley?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Is parking a problem for a job in Bromley?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

How much does commercial sealant cost in Bromley?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

Can I add another job to the visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Is it OK to seal over old sealant?

No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Commercial sealant around Bromley

Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. Bromley has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

If you look after a church, hall or community building such as Bow Church, halls and community kitchens see heavy use, and their sealant shows it. As a London address, Bromley can be tricky for parking: let us know about parking bays, permits or a driveway.

When something else is needed

Some problems need a builder, plumber or other trade rather than us:

  • Fire risk assessments or certification
  • Poor ventilation that keeps bringing mould back

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Do you need commercial sealant in Bromley?

Quick fixes come back quickly. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.

If you can see any of these, it’s time to have the joints looked at:

  • Tired sealant ahead of a health and safety audit
  • Mouldy bathrooms flagged at a tenancy check
  • Repeated reseals that don’t last
  • Split sealant around staff kitchen worktops and sinks

Letting a property close to West Ham station? Then we can quote for one property or a whole portfolio of rentals.
