Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Stopping sealant from ever changing colour outdoors
  • Materials with mixed tones that defy a single match
  • Paint over sealant on joints that move too much

If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer.

What we seal

  • Office fit-out finishes
  • Cladding panels
  • Natural stone and brick
  • Hotel bathrooms and public areas
  • Shop-fit joinery and counters
  • Powder-coated and anodised frames

How we handle coloured sealant in Leysdown-on-Sea

Architects, designers and brand teams often specify the sealant colour as carefully as the finishes around it. Most sealant types are made in a broad range of standard colours, and we will confirm the colours available for the specified product before we quote. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. We work on hotel bathrooms and public areas, natural stone and brick and office fit-out finishes, and the failures we’re asked to look at most are sealant that no longer suits recoated frames and discoloured joints on a visible elevation. Whether you call it commercial sealant work, mastic application or joint sealing, in Leysdown-on-Sea it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Commercial sealant work around smaller places like Leysdown-on-Sea tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Aftercare for building managers

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep the same sealant colour across a brand
  • Avoid piecemeal repairs on coloured joints
  • Don’t let trades patch coloured joints with a random sealant
  • Keep harsh solvents away from visible joints

Keep a record of the product and colour reference used. Future repairs can then use the same colour, with no guesswork.

Settle the colour early in the project. When colour is left to the last minute, it is often wrong, so agree it with the designer at the start.

FAQs: Leysdown-on-Sea

Is Leysdown-on-Sea too far out for you?

Not at all. Leysdown-on-Sea is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you supply sealant in our brand colour for a site in Leysdown-on-Sea?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can the building stay open while you work?

Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How much does the work cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Leysdown-on-Sea can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We confirm the joint type and the product it needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. We remove the masking and walk the finished joints with you.

Before we start on site

  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
