FAQs: Cranbrook Common

Do you offer colour-matched sealant for buildings in Cranbrook Common?

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.

Is Cranbrook Common too small for you to travel to?

No. Places such as Cranbrook Common are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you supply RAMS and insurance details?

The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

About our commercial sealant contractors in Cranbrook Common

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that typically surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Cranbrook Common. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you have wall and floor joints that have lost their seal and frame mastic that has hardened and come away from the wall, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Cranbrook Common, preparation and product choice get the time they need.

Multi-site clients with buildings in and around Cranbrook Common can put several sites on one programme, with one quote format and one point of contact.

In and around smaller places such as Cranbrook Common, the commercial buildings we’re 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.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, ring 01277 525 020 or use the quote form and we’ll come back to it.

What we’re called out for in Cranbrook Common

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

Things that typically lead to an enquiry:

  • Messy, uneven beads from earlier work that let the building down
  • A top-up bead over failed sealant, now lifting
  • Expansion joints with the sealant torn out
  • Weathered facade sealant that no longer flexes

A hotel such as Wilsley Hotel (to the south-west of Cranbrook Common) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Before you book anyone

  • How the existing material will be dealt with
  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • What site paperwork they can supply

Questions to ask before you appoint anyone

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Honest limits

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

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Walls or slabs moving more than any sealant can take
  • Water from a services leak rather than a joint

If in doubt, ring 01277 525 020 or use the quote form and we will say what we think before you book.

Joints and surfaces we work on

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

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Cranbrook Common can be grouped with others nearby. You will have a fixed quote before work starts.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached

How the job changes by surface

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, phasing the rooms so not every toilet is closed at once.

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. Tell us your trading hours and access windows and we’ll plan around them, phasing areas so the shop floor stays usable.

Commercial clients in Cranbrook Common

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Cranbrook Common can form part of a wider programme across Kent.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

What Cranbrook Common’s businesses ask us to seal

A 2-mile radius around Cranbrook Common takes in several hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, and the work can be phased so the rest of the hotel keeps trading. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Staplehurst station, 3.5 miles to the north of Cranbrook Common, footfall is part of the plan: work is phased so shops and offices keep trading.
