Mastic sealing in Ringlestone

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. We work on balcony and threshold joints, communal entrances and stairwells and communal kitchens and washrooms, and the failures we are asked to look at most are cracked, hardened mastic round windows on a block and draught complaints from residents or tenants. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Ringlestone is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Owners with buildings around smaller places like Ringlestone often group mastic work so one visit covers several properties. One quote can cover a whole list of addresses.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we’re called out for in Ringlestone

UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

Common reasons buildings call us in:

  • Failed external movement joints
  • Water getting in round frames after rain
  • Window mastic that has split and shrunk
  • Estate-wide sealant that is simply worn out

If your remit includes a building such as North Borough Junior School, frame and door mastic can be programmed for the holidays.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

Mastic sealing in Ringlestone: the local picture

Central London is about 30 miles from Ringlestone. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Ringlestone has two care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.

Buildings close to stations like Maidstone Barracks station, 0.8 miles south of Ringlestone, are often flats over shops, with frame mastic to keep sound. Landlords with units on estates such as Mid Kent Shopping Centre (0.8 miles west of Ringlestone) can bring frame, door and external mastic across several units into one programme.

Ringlestone is about 2 miles north of Maidstone, in Kent. Anywhere in ME14, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Ringlestone is one of 931 places we cover in Kent. Sites around London have their own page, about 30 miles away.

Work on mastic joints is covered throughout ME14 and ME16, whatever the building. For a building on Hyde Road, Mill Lane and Edna Road or nearby, we can quote for mastic joints. Sites close to Ringlestone are covered too, including Sandling (1 mile north), Abbey Gate (1 mile north), Foley Park (1 mile south-east), Penenden Heath (1 mile south-east) and Harbourland (1 mile east). Bigger towns within reach include Sittingbourne (10 miles east), Sevenoaks (14 miles west), Royal Tunbridge Wells (15 miles south-west), Gravesend (11 miles north-west), Tonbridge (12 miles south-west) and Northfleet (12 miles north-west).

Different surfaces, different methods

Communal areas

We keep entrances and stairs open throughout. We work in sections so access is never blocked.

External movement joints

External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.

Cost factors for mastic joints

We price every job individually. The things that drive the figure:

  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • How much there is to seal

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Details that help us quote

However big the job, these details speed things up:

  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • The product your specification calls for
  • The type of building and who uses it

For a fixed quote, call 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. You can also send details through our quote form.

When to bring in a specialist

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.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. What matters most for a job in Ringlestone is a clear list of what needs doing. A fixed quote follows.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings

Getting a fixed quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Substrate edges that need repairing first
  • Leaks from above rather than through a joint
  • Misted or failed double-glazed units

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Can you seal joints high up on a block?

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
