When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Old mastic that tests positive for asbestos
  • Roof leaks that only look like a joint problem

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Surfaces we seal

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

About our commercial sealant contractors in Stoke

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have sanitary sealant that has gone black and patchy and water staining near frames, panels or ceilings, we can help, whatever the surface. Whoever orders the work in Stoke, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In an occupied building in Stoke, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

Rural business units near smaller places such as Stoke are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Why act early in Stoke

Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. One visit to deal with every failing joint makes more sense than several trips to a place like Stoke. Photos of every joint help us quote for the whole job.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you’re ready.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Stoke can sit alongside others in a wider programme across Medway.

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.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Stoke may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Sealant on show in Stoke’s commercial buildings

Stoke lies within about 1 mile of the sea. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. We choose a product rated for the exposure, then confirm the colours available for it. At about 31 miles from central London, Stoke is within reach of the capital. The commuter belt holds a great many offices, retail parks and business parks. If you have premises across the region, one contractor can cover them all.

Where a joint is on show in Stoke, we will check which shades the product offers before work starts. Whatever the building in Stoke, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Stoke is about 5 miles north of Gillingham, in Medway. Stoke sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Stoke is one of 54 places we cover in Medway. Sites around London have their own page, about 31 miles away.

What the job involves on each surface

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services.

Window and door perimeters

The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Stoke: questions and answers

Do you offer colour-matched sealant for buildings in Stoke?

Yes, we can typically get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Is a smaller place like Stoke outside your area?

No. Places such as Stoke are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What do you need from us to quote?

Send photographs, drawings or a list of locations. Where we need to see it, we will arrange a site visit, then send a fixed quote.

Is it OK to apply fresh sealant over existing beads?

Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What guarantee do you give on resealing?

Each job sits under our 12-month guarantee, starting at sign-off. Looking after the joints as we advise helps them last.
