Mastic sealing in Cocking Causeway

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and movement joints with sealant missing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Cocking Causeway is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For owners with a single building near Cocking Causeway, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

After the work

Once the work is signed off, a little attention goes a long way:

  • Reduce knocks to communal area joints
  • Check sealant joints during planned building inspections
  • Look at the sunniest and most exposed elevations first
  • Log resealing dates block by block

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.

Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • The size and state of each joint
  • How much there is to seal

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

What we need to price the job

The more we know, the firmer the quote. Helpful details to send:

  • Your programme or deadline
  • The postcode of the building
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, ring 01277 525 020 or email drawings and photos.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Cocking Causeway are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  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.

Preparing the site

  • Tell us which areas need to stay in use

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Failed window or door frames, which need a window contractor
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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

How the job changes by surface

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Commercial and mixed-use buildings

Commercial occupiers typically stay open during the work, so we plan around them.

FAQs: Cocking Causeway

Can one quote cover a number of our buildings near Cocking Causeway?

Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.

Is Holmbush Industrial Estate, near Cocking Causeway, within your area?

Yes. We cover Cocking Causeway and the area around it, including industrial estates, business parks and retail parks such as Holmbush Industrial Estate. Photos and a short description are enough for a first look.

Do you work for managing agents and housing associations?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it.

Do you cover Cocking Causeway?

Yes. Sites across Cocking Causeway are covered, with one number for every area we cover.

Block-wide mastic in Cocking Causeway

Cocking Causeway lies roughly 46 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

Historic properties like Cowdray House (1.2 miles north of Cocking Causeway) show the age of some local stock, where frame mastic must suit soft brick or stone. Older community buildings, The Parish Church of St Mary Magdalene among them, often have frames of mixed ages whose mastic varies. Property owners at sites such as Holmbush Industrial Estate, 0.5 miles to the north-west of Cocking Causeway, can have mastic renewed between lettings.

Cocking Causeway is about 9 miles east of Petersfield, in West Sussex.

What happens if it’s left?

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Halls, stores and units around places like Cocking Causeway may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
