How the job changes by surface

Hotel bathrooms

Early starts or out-of-hours work can be arranged around check-out and check-in, with the order agreed with your team.

Retail & leisure sites

Gym and leisure changing rooms take heavy use and plenty of water, so anti-fungal sanitary silicone is the product we use.

Commercial sealant in Burn's Green, done properly

We fit the work around your building. Rooms can be done one at a time, floor by floor or in batches, and early starts or out-of-hours working can be arranged. If you’re dealing with water marks on ceilings under bathrooms and worktop sealant that has shrunk and stained, we can put it right, whatever the surface.

Work in a small place like Burn's Green is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.

You get a one-year guarantee, the same in Burn's Green as everywhere else we work.

How to look after the new joints

A little care helps the new joints last. We recommend:

  • Plan resealing around quiet periods
  • Leave squeegees in busy showers
  • Ask cleaners to go gently on the silicone
  • Give housekeeping the cure time for every room

Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.

A room that can’t be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.

What commercial sealant looks like in Burn's Green

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

For buildings such as Parish Church of St Peter, its kitchen and washroom sealant needs looking after like anywhere else. Rented homes near Watton-At-Stone station change hands often, and sealant work can be quoted for a single flat or a whole portfolio.

Common questions in Burn's Green

Do you work for landlords with property near Watton-At-Stone station?

Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.

Can you do commercial sealant in Burn's Green?

Yes, Burn's Green is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.

Can you match the sealant colour?

Most of the time, yes. We will tell you which colours the right product comes in and agree one before any work starts.

Will there be a smell?

Some sealants have a smell while they cure. Ventilation helps.

Do you take out the old sealant first?

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

Is commercial work guaranteed?

Yes, for 12 months. Regular gentle cleaning and working extraction help the sealant last.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you take on a whole building?

Yes. After a site walk, we agree the scope and sequence, and give you one clear quote.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. Typically it takes as long as the scope needs, from one welfare room to a full building, and the area is left clean. Somewhere as small as Burn's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by looking at the rooms and agreeing what’s needed.
  2. We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
  3. Areas are protected and the failed sealant removed.
  4. Joints are dried, then resealed and tooled neatly.
  5. Housekeeping or site staff are told when each area can be used.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions

Getting a quote

It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.

What we can’t put right

To be straight with you, some problems need a different trade:

  • Poor ventilation that keeps bringing mould back
  • Fire risk assessments or certification
  • Failed tanking or loose tiles behind the sealant

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

What we seal

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

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Do you need commercial sealant in Burn's Green?

A rushed reseal between guests rarely lasts. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.

Signs it’s time to call us include:

  • Shower leaks reaching the floor below
  • Black, stained silicone in guest bathrooms
  • Worktop sealant that has shrunk and stained
  • Silicone laid over old silicone by a previous contractor

Schools such as Benington Church of England Primary School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.

Questions to ask before booking

  • What preparation is included
  • What the cure time is
  • Which colour the sealant will be
  • Who does the work, and how experienced they are

What affects the quote in Burn's Green

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site
  • How much there is to do
  • Mould in or behind the old joints

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’ll explain the quote if you ask.

Asking for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Access, such as stairs, a lift or height
  • The type of property
  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email

Need a quote? Please ring 0345 464 0079 or drop us an email and tell us about the job. We will explain what we’d do and give you a clear quote before any work starts.
