About our mastic sealing in Stonebridge Green

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have draught complaints from residents or tenants and estate-wide sealant that is simply worn out, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Stonebridge Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions near places like Stonebridge 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.

Every job we finish is backed by a 12-month workmanship guarantee, in Stonebridge Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Blocks and managed buildings in Stonebridge Green

Stonebridge Green is about 41 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Stonebridge Green is in the South East, one of the UK’s drier regions. 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.

Blocks of flats and mixed-use buildings often cluster around stations such as Charing station, 2.2 miles to the east of Stonebridge Green, and their window and balcony mastic tends to age at the same rate across a building. Historic properties like Godinton House, 5 miles to the south-east of Stonebridge Green, show the age of some local stock, where frame mastic must suit soft brick or stone.

Stonebridge Green is about 7 miles north-west of Ashford, in Kent. We send applicators to Stonebridge Green for mastic joints, handled exactly as we handle every other area. We work across 931 places in Kent, large and small. We also cover London, some 41 miles away.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Share the asbestos register when you send details
  • Make mastic part of routine maintenance checks
  • Mention RAMS, insurance or CSCS requirements up front
  • Protect low-level joints in entrances

Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.

Why it’s worth doing now in Stonebridge Green

Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. One visit to deal with every failing joint makes more sense than several trips to a place like Stonebridge Green. Photos of every joint help us quote for the whole job.

A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Your questions answered

Is Stonebridge Green off your patch?

No. Places such as Stonebridge Green are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

We manage a building near Charing station. Can you help?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Can you take on resealing for a block portfolio?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Cost factors for mastic joints

Each job is priced on its own details. The things that drive the figure:

  • The site’s rules and procedures
  • The size and state of each joint
  • How much existing material needs removing
  • Phasing around occupants

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around
  • Whether the building will be occupied during the work

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. For work around Stonebridge Green, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Tell us which areas need to stay in use

Advice

Signs you need mastic sealing in Stonebridge Green

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.

Site and facilities staff are often the first to spot these:

  • Leaks at window and door perimeters
  • Damaged joints in communal entrances and corridors
  • Movement joints with sealant missing
  • Estate-wide sealant that is simply worn out

Churches, halls and community buildings such as Church of St James are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
