Commercial sealant in Dulwich Village, done properly

Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. Several addresses can go on one quote. We work on hotel bathrooms, welfare facilities and retail & leisure sites, and people most often call us about leaking joints in shower rooms and changing areas and leaks from showers into rooms or ceilings below.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Where a building in Dulwich Village needs to stay open, work can be planned outside normal hours.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes as long as the scope needs, from one welfare room to a full building, and the area is left clean. For a job in Dulwich Village, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. First we visit and agree the scope, the sequence and the working hours.
  2. Room by room, we protect the area and remove all the old sealant.
  3. We clean the joints, treat any mould and let them dry.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Rooms are checked and returned with a cure time so staff know when to use them.

How to prepare

  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height
  • Mention any parking rules near the property

Commercial buildings in Dulwich Village

London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

Dulwich Village is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Landlords, agents and businesses in Dulwich Village

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

For anyone letting property in or around Dulwich Village, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.

Leave it or put it right?

Before an inspection, audit or busy season, sealant is easy to overlook. Planning the work ahead means rooms are finished and cured in time, without a last-minute rush. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Dulwich Village, the repair is bigger than a sealant job.

Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Surface by surface

Rental portfolios

A sound seal protects the property as well as its appearance.

Retail & leisure sites

Customer toilets reflect on the business, and fresh sealant makes them look well kept.

Keeping the joints in good condition

Simple care keeps the joints in good condition. We recommend:

  • Get split or lifting joints looked at early
  • Book larger programmes for quieter times of year
  • Check extract fans are actually running
  • Pass on the cure time to whoever cleans the rooms

Strong chemicals and scourers wear silicone out faster. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.

Signs to look for: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.

When it isn’t the sealant

Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:

  • Extraction that isn’t working, which needs an electrician or ventilation contractor
  • Certifying fire stopping or building compliance
  • Cracked trays or baths rather than failed joints

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Questions from Dulwich Village

Can parking be tricky for a visit in Dulwich Village?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Is Dulwich Village in your area for commercial sealant?

Yes. We work across London and the South East, and Dulwich Village is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures.

Can you reseal between tenancies?

Yes, we can. Tell us the addresses and the rooms, and we will quote for the lot.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can I choose the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
