Mastic sealing for businesses in Dungate

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle mastic sealing in Dungate

Managing agents and housing associations usually need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve a mix of products and colours from past repairs and water getting in round frames after rain, across communal kitchens and washrooms, communal entrances and stairwells and external wall and movement joints. Most enquiries from Dungate 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.

Around smaller places like Dungate, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we will arrange a return visit.

Mastic sealing around Dungate: points for this area

Dungate sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 39 miles from Dungate. Within reach of London, blocks run by agents and associations are common around stations.

For owners of several units at places like Kent Science Park, 1.3 miles to the north-west of Dungate, one programme can deal with frame and external mastic across the lot. If you’re responsible for a building such as Church of St Catherine, frame and door mastic needs the same attention as any other property. Blocks of flats and mixed-use buildings often cluster around stations such as Sittingbourne station, 2.9 miles to the north of Dungate, and their window and balcony mastic tends to age at the same rate across a building.

Dungate is about 3 miles south of Sittingbourne, in Kent. If you are looking for mastic sealing in Dungate, we can help. We work across 931 places in Kent, large and small. Sites around London have their own page, roughly 39 miles from Dungate.

Leave it or put it right?

Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work and less choice about when. Halls, stores and units around places like Dungate may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why clients in Dungate choose us

  • Health and safety: CHAS accredited
  • Matching to RAL references, product permitting
  • 12 months’ guarantee on every job
  • One number for every site we cover

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Frames that are rotten, warped or broken
  • Water coming in from the roof or rainwater goods

Not sure which it is? You can call 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Surfaces we seal

  • Shopfronts below residential blocks
  • External wall and movement joints
  • Balcony and threshold joints
  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Window and door perimeters on blocks

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Dungate are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

What we need from you

  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work
  • Point out any areas we must not close

Quoting for work in Dungate

Quotes vary with the job. Expect it to depend on:

  • The product specified
  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers
  • Whether the work must be split into stages

Access often affects the price as much as the sealing: 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.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • A wide shot and a close-up of the area
  • The postcode of the building
  • The type of building and who uses it
  • Specification clauses that apply

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or send photos by email with what you know.

How the job changes by surface

Communal areas

Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Tidy, sound joints keep them looking cared for.

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading, so we plan around them.
