Commercial sealant contractors in Little Chart, done properly

Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them; 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 wall and floor joints that have lost their seal and external beads that have gone brittle and cracked, we can put it right, on external facade joints, movement joints in walls and floors and window and door perimeters alike. Facilities teams, main contractors and managing agents in Little Chart tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

A lot of what we do in Little Chart is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Commercial sealant work around smaller places like Little Chart tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When to call us in Little Chart

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 all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants.

Most enquiries start with something like this:

  • Messy, uneven beads from earlier work that let the building down
  • Sanitary sealant that has gone black and patchy
  • Expansion joints with the sealant torn out
  • External beads that have gone brittle and cracked

For premises near Charing station (2.1 miles north of Little Chart), footfall is part of the plan: work is phased so shops and offices keep trading.

Questions to ask before you book

  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Suspect materials that need testing and specialist removal
  • Cracking that needs a structural engineer to look at it
  • Misted, cracked or failed glazing units (a glazier’s job)

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.

Where we work in Little Chart

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

Working on commercial sites near Little Chart

Little Chart is about 44 miles from central London. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

For any commercial premises in Little Chart, a lasting joint depends on full removal of the old sealant and clean, dry faces.

Little Chart is about 5 miles north-west of Ashford, in Kent. Looking for commercial sealant contractors in Little Chart? We can help, as we do across Kent. Across Kent, 931 places are covered, Little Chart among them. Sites around London have their own page, about 44 miles away.

Why deal with it now?

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation. It shows over the following seasons rather than at handover. One visit to deal with every failing joint makes more sense than several trips to a place like Little Chart, rather than one at a time. Photos of every joint help us quote for the whole job.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What you get with us

  • Matching to RAL references, product permitting
  • Work carried out by CSCS-carded applicators
  • Colour agreed before work starts
  • Standard and matched colours in many product ranges

Your questions answered

Do hotels near Little Chart have to close for sealant work?

In most cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.

Can the sealant on our Little Chart premises match the finishes?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we will confirm what’s available for the product.

How long does a typical visit take?

It depends on the scope, though a typical visit normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. For bigger or phased jobs, we will set out a timescale with the quote.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What about asbestos in old mastic?

It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Owners, agents and contractors

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. Little Chart can form part of a wider programme.

Keeping the joints sound

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

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Make sure ventilation in wet areas is switched on and working
  • Log reseals in the O&M or maintenance records
  • Respect the cure time before reopening an area

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.

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.

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Little Chart, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, and a site visit is booked where it helps.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  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.

Before we start on site

  • Point out any areas we must not close
  • Send your site hours and access windows
  • Flag any permit to work we’ll need

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
