Construction mastic for Biddenden Green sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Biddenden Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

Preparing the site

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use

Advice

How we handle construction mastic in Biddenden Green

The specification and the programme set the job. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. If you’re dealing with cracks opening in caulked internal joints and external joints sealed in damp or cold conditions that are now failing, we can help, on brick and block movement joints, cladding and panel joints and sanitary and kitchen joints alike. Most enquiries from Biddenden Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Construction in and around smaller places such as Biddenden Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Biddenden Green clients

Would you work within a site like Benenden Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Biddenden Green too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How many days will you need on site?

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

Why act early in Biddenden Green

Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to. Damaged joints are removed and resealed from clean faces. Older rural buildings around Biddenden Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Specification-led, product-correct work
  • Workmanship guaranteed for 12 months
  • Standard and matched colours in many product ranges
  • CSCS-carded applicators

Cost factors for mastic packages

The price varies from site to site. It mainly depends on:

  • Any access equipment needed
  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Whether the work must be split into stages

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Sending details for a quote

A few photos plus some basic facts will normally do. It helps to include:

  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Any dates the work must fit around

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call the office on 01277 525 020 or use the quote form.

When to bring in a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Commercial clients in Biddenden Green

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Biddenden Green can sit alongside others in a wider programme.

What the job involves on each surface

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere.

Mastic packages on Biddenden Green sites

Biddenden Green is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Biddenden Green lies roughly 42 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

New wings at hospitals like Benenden Hospital, 5.9 miles south-west of Biddenden Green, bring long runs of window and panel joints to seal. When a school such as Smarden Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Biddenden Green is about 7 miles west of Ashford, in Kent. We cover Biddenden Green, with the same fixed quotes and 12-month guarantee as everywhere else. Biddenden Green is one of 931 places we cover in Kent for mastic packages. London is covered too, around 42 miles from Biddenden Green.
