Commercial sealant in Telegraph Hill, done properly

Guest bathrooms are cleaned every day and used by different people every night, so sealant there has a hard life. We work through rooms in batches, so only a few are out of use at once, with a cure time for each room so housekeeping know when to release it. We work on rental portfolios, student & care accommodation and office washrooms & kitchens, and common reasons people get in touch are repeated reseals that don’t last and large numbers of bathrooms needing the same work.

Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Telegraph Hill.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Common questions in Telegraph Hill

Can you help a landlord with a rental near Brockley station?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Is Telegraph Hill in your area for commercial sealant?

Yes. Our work covers London and the South East, and Telegraph Hill is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.

How long does the job take?

Typically it takes as long as the scope needs, from one welfare room to a full building. Bigger jobs take longer, and we’ll say how long yours will take.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Where do you work from?

We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Can I do it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Is there any odour?

There can be a smell while the sealant cures. Opening a window helps.

Do you need commercial sealant in Telegraph Hill?

Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading all work at the joint. If a tray flexes, the sealant around it splits.

It’s worth asking for a quote if you see:

  • Whole floors of tired en suites
  • Washrooms that need sorting before an inspection
  • Mouldy bathrooms flagged at a tenancy check
  • Split sealant where wet room floors meet walls

For buildings such as St Catherine's Hatcham, its kitchen and washroom sealant needs looking after like anywhere else.

Before you book anyone

  • Are they insured?
  • Whether the sealant suits the joint
  • Who does the work, and how experienced they are
  • How the colour is chosen

Choosing a sealant specialist

What we can’t put right

We won’t take on work that won’t last, so these are the limits:

  • Fire risk assessments or certification
  • Damaged sanitaryware that needs replacing
  • A broken extractor fan behind the mould problem

If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Joints and surfaces we work on

  • Student & care accommodation
  • Retail & leisure sites
  • Rental portfolios
  • Hotel bathrooms
  • Office washrooms & kitchens
  • Welfare facilities

Why act early in Telegraph Hill

Sealing over the old bead can seem the fastest option, but it will not bond, and it lifts again soon. One proper reseal beats several quick ones. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why us?

  • Homes, businesses and hotels
  • An ARBOMaster approved applicator
  • Old sealant always removed completely
  • A choice of colours where the product allows

What commercial sealant looks like in Telegraph Hill

London has hard water, which leaves limescale on sealant, grout and taps. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

Telegraph Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as Haberdashers' Hatcham College are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.

What happens on the day

Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours per room, so whole buildings are phased. In Telegraph Hill, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
  3. In each room, the old bead comes out and the joint is cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Each finished area is checked with you and given a cure time.

Before we arrive

  • Mention any tricky access
  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we’re working on
