What we are called out for in Ightham

Outside, sunlight and rain wear sealant down year after year. Sunny elevations dry the surface out and exposed ones take driving rain. Once it stiffens, the joint opens up at the next big temperature swing.

These are often picked up first by site or facilities staff:

  • Black mould through washroom sealant that won’t clean off
  • Damp patches where an external joint has failed
  • Gaps behind commercial kitchen worktops and sinks
  • Wall and floor joints that have lost their seal

Occupiers with premises at both Bourne Enterprise Centre and Chaucer Business Park could have the sealant at each handled under one quote.

Before you book anyone

  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants

How to choose a sealant contractor

How we handle commercial sealant contractors in Ightham

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Ightham, call the office on 01277 525 020 or email the details over with the site addresses. We work on floor and threshold joints, external facade joints and kitchen worktops and splashbacks, and the failures we are asked to look at most are expansion joints with the sealant torn out and frame mastic that has hardened and come away from the wall. Most enquiries from Ightham start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In Ightham, as anywhere, the first joints to go are usually the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

In and around smaller places such as Ightham, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Common questions from Ightham clients

Is Ightham too far out for you?

Not at all. Ightham is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Bourne Enterprise Centre, near Ightham?

Yes, sites like Bourne Enterprise Centre are within our area, along with the rest of Ightham. Send details of the unit and the work through our quote form for a quick quote.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Which site documents can you send us?

Let us know your requirements when you ask for a price. For older buildings we’ll ask for the asbestos register, plus your site induction rules.

Is failed sealant stripped out, or sealed over?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves, so it isn’t something we do.

Can one contractor look after sealant on all our buildings?

Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.

How do you keep disruption to occupiers down?

Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.

When to bring in a specialist

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

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Cost factors for sealant joints

Each job is priced on its own details. The main factors are:

  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • The size and state of each joint
  • Whether the work must be split into stages

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

A good diagnosis starts with the right details. Tell us:

  • The product your specification calls for
  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Clear photographs of the problem areas

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • A failed roof covering or waterproofing membrane
  • Old mastic that tests positive for asbestos
  • Faulty windows rather than failed perimeter sealant

Not sure which it is? You can call 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
  • Floor and threshold joints
  • Kitchen worktops and splashbacks
  • External facade joints
  • Window and door perimeters
  • Washrooms and tea points

How a job runs

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Rural sites near Ightham 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. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  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.

What we need from you

  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
  • Have the specification and drawings to hand

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Why it’s worth doing now in Ightham

Leaving a failed joint rarely saves money. 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. Resealing while only the sealant has failed keeps the job small. Converted and older buildings near places like Ightham tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Why clients in Ightham choose us

  • Fixed quotes based on photographs, drawings or a visit
  • Failed material removed, not covered up
  • Matching to RAL references, product permitting
  • Colours confirmed for the specified product

Working on commercial sites near Ightham

Ightham is in the South East, one of the UK’s drier regions. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Central London is about 22 miles from Ightham. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

For premises near Borough Green & Wrotham station (1.5 miles north-east of Ightham), footfall is part of the plan: work is phased so shops and offices keep trading. On a business park such as Bourne Enterprise Centre, which lies north-east of Ightham, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
