Construction mastic for Wissenden sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle construction mastic in Wissenden

On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers with projects in Wissenden. Most enquiries involve window and door perimeters that won’t pass inspection and different trades sealing to different standards, across floor and skirting junctions, sanitary and kitchen joints and internal decorators’ caulk. A single leaking joint is often how a building in Wissenden first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Wissenden can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.

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

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Wissenden can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with the drawings, specification and programme.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in

Getting a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Contractors’ notes for Wissenden

Wissenden lies roughly 43 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. The South East is one of the drier 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 a contractor working at a hospital such as Benenden Hospital, 6 miles south-west of Wissenden, perimeter and facade sealing is planned around patients and deliveries. Historic houses such as Godinton House, 4.8 miles east of Wissenden, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Wissenden is about 6 miles west of Ashford, in Kent. We send applicators to Wissenden for mastic packages. Wissenden is one of 931 places we cover in Kent. For work in that direction, see our London page.

Questions we’re asked in Wissenden

Is a hospital such as Benenden Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Will you fit the mastic around our build programme in Wissenden?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What happens if the weather stops external sealing?

External sealant needs a dry joint and a temperature within the product’s range. Frosty or damp mornings can hold up external sealing.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Is the mastic package guaranteed?

Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

We work for building owners and managing agents on everything from one building to a spread of sites around Wissenden. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What the job involves on each surface

Bathrooms, en suites and washrooms

On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.

Signs you need construction mastic in Wissenden

A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.

Things that typically lead to an enquiry:

  • Oversized or tapered gaps around new frames
  • Sealant knocked or painted over by other trades
  • Failed sealant in an existing building being refurbished
  • Frame perimeters left unsealed or poorly sealed

When a school such as Bethersden Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

What to look for in a quote

  • What site paperwork they can supply
  • Do they follow the manufacturer’s priming guidance?
  • Which product they’ll use, and why it suits the joint
  • How the existing material will be dealt with

Cost factors for mastic packages

These are the things that shape the price:

  • How much there is to seal
  • Phasing around occupants
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • Any dates the work must fit around
  • Where the site is, with the postcode
  • The type of building and who uses it

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why it’s worth doing now in Wissenden

When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we’ll say so. Converted and older buildings near places like Wissenden tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • Products installed to the manufacturer’s instructions
  • Colours chosen to suit frames, cladding or finishes where possible
  • Fixed quotes based on photos, drawings or a visit
  • Constructionline member
