How we handle mastic sealing in Nettlestead Green

Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. Site teams most often ask us about estate-wide sealant that is simply worn out and cracked, hardened mastic round windows on a block, across shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints. Most enquiries from Nettlestead Green 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.

Rural conversions near places like Nettlestead Green often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

For owners and agents in Nettlestead Green

Nettlestead Green sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 28 miles from Nettlestead Green. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.

Owners of student blocks near University for the Creative Arts - Maidstone (to the north-east of Nettlestead Green) can schedule frame and external mastic for the summer vacation. With historic buildings such as Old Soar Manor (to the north-west of Nettlestead Green) in the wider area, owners of older properties around Nettlestead Green should expect mastic to need a product that suits old masonry. If you look after a block within reach of Yalding station, which lies south-east of Nettlestead Green, frame and balcony mastic can be renewed on one programme.

Nettlestead Green is about 6 miles south-west of Maidstone, in Kent. We send applicators to Nettlestead Green for mastic joints. Across Kent, 931 places are covered, including Nettlestead Green. For work in that direction, see our London page.

What the job involves on each surface

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading so the work is phased.

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.

Leave it or put it right?

Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Around Nettlestead Green, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What you get with us

  • 12 months’ guarantee on every job
  • Constructionline member for supplier checks
  • CHAS accredited contractor

Your questions answered

Will you take on work at estates like Woodfalls Industrial Estate, close to Nettlestead Green?

Yes, sites like Woodfalls Industrial Estate are within our area, along with the rest of Nettlestead Green. A few photographs and the unit address let us price the work.

Is Nettlestead Green off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

What do you charge?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

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 external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

On site: what to expect

Advice

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What sets the cost

What shapes the price:

  • How much there is to seal
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • The site address and postcode
  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • The product your specification calls for

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email a schedule or drawings.
