How the job changes by surface

Shop fronts and retail fit-outs

In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal, frequently colour-matched to the fit-out. We will confirm the colours available for the specified product.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. We confirm the access in place before we quote.

Sealant specialists in Marsh Gibbon

How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you have messy, uneven beads from earlier work that let the building down and wall and floor joints that have lost their seal, we can help, on window and door perimeters, floor and threshold joints and external facade joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Marsh Gibbon, preparation and product choice get the time they need.

In Marsh Gibbon, as anywhere, the first joints to go are normally the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Commercial sealant work around smaller places like Marsh Gibbon 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.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Questions about Marsh Gibbon

Can the sealant on our Marsh Gibbon premises match the finishes?

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.

Is a smaller place like Marsh Gibbon outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What do you need from us to quote?

Send photographs, drawings or a list of locations through our quote form. If a visit is needed we will book one, and a fixed quote follows.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Is it OK to apply fresh sealant over existing beads?

The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Check sealant as part of routine building inspections
  • Don’t let cleaning or traffic back on before the cure time is up
  • On pre-2000 buildings, share the asbestos information before work starts
  • Ask cleaners to use a soft cloth and mild cleaner on sealant

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.

Tenants and staff spot black or split sealant quickly. Planned replacement saves fielding the same complaint again and again.

Quoting for work in Marsh Gibbon

Before we quote, we look at:

  • The product specified
  • Phasing around occupants
  • How accessible the joints are
  • Joint width, depth and condition

A quote for sealant joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email us.
