When it is not the sealant

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

  • Poor ventilation that keeps bringing mould back
  • Leaking pipework, valves or wastes (a plumber’s job)
  • Fire risk assessments or certification

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

Surfaces we seal

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

How we handle commercial sealant in Donnybrook Quarter

For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. We can quote for several properties at once. We work on student & care accommodation, retail & leisure sites and office washrooms & kitchens, and common reasons people get in touch are large numbers of bathrooms needing the same work and worktop sealant that has shrunk and stained.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Donnybrook Quarter, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

How the job changes by surface

Hotel bathrooms

In a hotel, every bathroom is used and cleaned daily, so we use anti-fungal sanitary silicone and finish joints smooth for easy cleaning.

Retail & leisure sites

Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.

What affects the cost of commercial sealant

There’s no set price list, because jobs vary so much. The quote depends on:

  • How many rooms, windows or areas are involved
  • Any working-time requirements on site
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What to tell us for a quote

You don’t need to know the technical terms. Just tell us:

  • The rough size of the job
  • Any access issues, like height or stairs
  • Where the property is
  • Whether it has been sealed before

We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or send us an email with the details, and pictures are welcome.

How the visit works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on the number of rooms. For a job in Donnybrook Quarter, 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. We walk the site with you and agree the rooms, the order and the hours.
  2. Every area is sheeted and the old silicone stripped out.
  3. We clean the joints, treat any mould and let them dry.
  4. New sealant suited to each area is applied and tooled.
  5. We check every room and give its cure time for housekeeping.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Plan for the work area to be out of bounds to pets and children
  • Clear items away from the joints we are working on

Related advice

What we are called out for in Donnybrook Quarter

A hotel shower or office washroom is used many times a day, and they’re cleaned with strong products every day. That is why sealant fails sooner.

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

  • Tired sealant ahead of a health and safety audit
  • Worktop sealant that has shrunk and stained
  • Failed floor-level joints in accessible wet rooms
  • Silicone laid over old silicone by a previous contractor

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

DIY sealant or a professional job?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

FAQs for Donnybrook Quarter

Is parking a problem for a job in Donnybrook Quarter?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Do you take on hotel work around Donnybrook Quarter?

Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.

Can you reseal between tenancies?

Yes. We reseal bathrooms and kitchens in rented homes and several properties can be quoted together.

Should I try DIY first?

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

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

How much does commercial sealant cost in Donnybrook Quarter?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Why act early in Donnybrook Quarter

Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. In a flat in Donnybrook Quarter, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
