Commercial mastic work in Swift's Green

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed, then both faces are cleaned back to sound, dry material with no dust or grease on them. Primer is used wherever the manufacturer calls for it on that surface. If you’re dealing with window and door perimeter joints that have cracked open and smeared sealant across finishes from a rushed job, we can put it right, whatever the surface. Looking for mastic applicators who cover Swift's Green? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

The most common commercial job in Swift's Green is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

In and around smaller places such as Swift's Green, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

FAQs: Swift's Green

Is Swift's Green too far out for you?

No. Places such as Swift's Green are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Barradale Farm Industrial Estate, near Swift's Green, within your area?

Yes. Our area takes in Swift's Green and its surroundings, with estates and business parks such as Barradale Farm Industrial Estate included. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is it OK to apply fresh sealant over existing beads?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Does commercial sealant work come with a guarantee?

A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Swift's Green can sit alongside others in a wider programme.

What we’re called out for in Swift's Green

The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.

Most enquiries start with something like this:

  • Frame mastic that has hardened and come away from the wall
  • Messy, uneven beads from earlier work that let the building down
  • Gaps behind commercial kitchen worktops and sinks
  • External beads that have gone brittle and cracked

Offices and shops close to stations such as Headcorn station (to the west of Swift's Green) tend to be busy all day, so sealant work is planned around opening hours.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Can the work be phased to keep areas open?
  • The named product and why it was chosen
  • What site paperwork they can supply

How to choose a sealant contractor

Leave it or put it right?

Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. Converted and older buildings near places like Swift's Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Standard and matched colours in many product ranges
  • Work carried out by CSCS-carded applicators
  • RAL and finish matching where the product range allows
  • Sealing commercial buildings since 2005

See our cost guide and how we’re accredited.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Faulty windows rather than failed perimeter sealant
  • A dripping trap, valve or pipe behind a fitting
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think before you book.

Surfaces we seal

  • External facade joints
  • Movement joints in walls and floors
  • Floor and threshold joints
  • Window and door perimeters
  • Washrooms and tea points
  • Kitchen worktops and splashbacks

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 usually costs more in the end than doing them right.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
