Sealant applicators in Stow Maries

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Primer is used wherever the manufacturer calls for it on that surface. We work on washrooms and tea points, window and door perimeters and external facade joints, and the failures we are asked to look at most are shrunken sealant along kitchen worktops and splashbacks and leaks that seem to come through a sealant line. For commercial sealant work in Stow Maries, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In Stow Maries, as anywhere, the first joints to go are typically the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

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

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email a schedule or drawings and we will come back to it.

What we are called out for in Stow Maries

A split down the middle of the bead tells a different story. That typically means the joint stretched further than the product could cope with: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds, which is why we look at the joint design as well.

Look out for the following:

  • Smeared sealant across finishes from a rushed job
  • Weathered facade sealant that no longer flexes
  • Leaks that seem to come through a sealant line
  • Mouldy silicone around WCs, urinals and vanity tops

Sites a few miles apart, such as Great Hayes Business Centre and Eastern Industrial Estate, can share one programme and one point of contact.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Do they follow the manufacturer’s priming guidance?
  • Are they CHAS accredited or on Constructionline?
  • How joint depth will be controlled

How to choose a sealant contractor

Surface by surface

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Deal with small splits before they become leaks
  • Respect the cure time before reopening an area
  • Keep a record of which joints were resealed and when
  • Check joints after other trades have worked nearby

Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, especially on exposed elevations and in washrooms. Should something look amiss, you can call 01277 525 020 or send details through our quote form and send a picture.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Suspect materials that need testing and specialist removal
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Broken glass or blown double-glazed units

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

What we seal

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

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Smaller jobs around Stow Maries can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First, details come to us: photographs, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached

Shops, offices and hotels in and around Stow Maries

Stow Maries sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Stow Maries is about 34 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

For premises near North Fambridge station, which lies south-east of Stow Maries, footfall is part of the plan: work is phased so shops and offices keep trading. If you run an office at a site such as Great Hayes Business Centre, which lies south of Stow Maries, the sealant at reception desks, tea points and frames ages with each fit-out.

Stow Maries is about 5 miles south of Maldon, in Essex. Businesses, contractors and managing agents in Stow Maries use us for work on sealant joints. Our Essex coverage takes in 644 places. We also cover London, some 34 miles away.
