Construction mastic for commercial buildings in Herne Pound

Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. We work on brick and block movement joints, cladding and panel joints and internal decorators’ caulk, and what we are called in for most is old sealant on a refurbishment that needs stripping before new work and cracks opening in caulked internal joints. A specialist sealant contractor works differently from a general builder: on jobs in Herne Pound, preparation and product choice get the time they need.

Sites around smaller places like Herne Pound can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to call us in Herne Pound

Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.

Look out for the following:

  • Window and door perimeters that won’t pass inspection
  • New external sealant already peeling away
  • Caulk cracking where joints are moving more than expected
  • Bath and shower joints scraped during the final clean

Units on estates such as The Alders Industrial Estate, 0.9 miles to the south of Herne Pound, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen

How to choose a sealant contractor

What happens if it’s left?

Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility and a consistent finish. Halls, stores and units around places like Herne Pound may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why choose Mastic Doctor in Herne Pound

  • Products installed to the manufacturer’s instructions
  • Sealing commercial buildings since 2005

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Contractors’ notes for Herne Pound

At about 26 miles from central London, Herne Pound is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Rainfall across the South East, Herne Pound included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors at a school such as Mereworth Community Primary School, sealing has to be finished before term starts. Extensions at sites like Maidstone Hospital, 4.6 miles east of Herne Pound, normally sit beside working departments, and the mastic follows strict access rules.

Herne Pound is about 6 miles north-east of Tonbridge, in Kent. Any commercial site in Herne Pound is covered, for single jobs and planned programmes alike. Across Kent, 931 places are covered, including Herne Pound. London is covered too, some 26 miles away.

Maintenance after handover

After handover, these steps help:

  • Use the product the specification names
  • Keep scrapers and abrasive pads off new beads
  • Share drawings and the specification as soon as possible
  • Brief following trades on areas that have been sealed

After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby.

A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Jobs in and around smaller places like Herne Pound are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First we look at the scope on site or from drawings.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
