About our commercial sealant contractors in Sway

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on movement joints in walls and floors, external facade joints and window and door perimeters, and the failures we are asked to look at most are expansion joints with the sealant torn out and damp patches where an external joint has failed. Whoever orders the work in Sway, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

On a typical commercial building in Sway, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Sealant jobs for businesses in a place the size of Sway are often best grouped: shopfront, washroom, kitchen and any external joints done together. Fewer visits means less disruption to trading.

Every job we finish is backed by a 12-month workmanship guarantee, in Sway as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. Proper degreasing comes before any new sealant.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Several jobs near Sway can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Point out parking and an unloading spot

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Walls or slabs moving more than any sealant can take
  • Leaks from pipework, wastes or valves (that’s plumbing)

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Common problems we fix in Sway

Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, so periodic inspection matters more than any date on a schedule.

Typical triggers for a call:

  • Mouldy silicone around WCs, urinals and vanity tops
  • Damp patches where an external joint has failed
  • Shrunken sealant along kitchen worktops and splashbacks
  • A top-up bead over failed sealant, now lifting

Shops and cafés around stations like Sway station (to the south-west of Sway) trade from early, so work is timed around them.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply
  • How the joint faces will be prepared and primed
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Report cracked or peeling sealant early
  • Look at the sealant around anything that has been moved or replaced
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Log reseals in the O&M or maintenance records

New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint. Leaving the area closed until then keeps the bead neat.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

Working on commercial sites near Sway

The area within 2 miles of Sway holds a number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading. Rainfall across the South East, Sway included, is lower than in many parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates.

In hotels such as Forest Heath Hotel, less than half a mile to the south of Sway, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Questions we’re asked in Sway

Will our hotel in Sway need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Can the sealant on our Sway premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photographs and we will confirm what’s available for the product.

What site paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What about asbestos in old mastic?

We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility, and we don’t remove asbestos-containing materials.

How many days will you need on site?

It depends on the scope, but the work typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we’ll set out a timescale with the quote.
