Mastic sealing for Great Canney sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Mastic sealing in Great Canney, done properly

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, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. Most enquiries involve old repairs sealed over failed mastic and window mastic that has split and shrunk, across communal kitchens and washrooms, communal entrances and stairwells and shopfronts below residential blocks. Most enquiries from Great Canney 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.

For buildings around smaller places like Great Canney, we group work so one trip covers it. Photos of each elevation help us quote accurately.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or send photos by email and we will come back to it.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Great Canney can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Agree which areas must stay open
  • Warn occupants and staff about the work

Great Canney: questions and answers

Is Great Canney too small for you to travel to?

Not at all. Great Canney is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you quote for a block close to North Fambridge station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.

Do you guarantee the mastic work?

A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Can people stay in the building while you reseal?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

What if the old mastic contains asbestos?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

What affects the price in Great Canney

We price every job individually. The main factors are:

  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back
  • Access details, including height
  • Whether the building will be occupied during the work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Block-wide mastic in Great Canney

Great Canney lies roughly 34 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Great Canney sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Blocks of flats and mixed-use buildings often cluster around stations such as North Fambridge station (2 miles south-east of Great Canney) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Great Hayes Business Centre, 1.3 miles to the south of Great Canney, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Site managers at schools like Cold Norton Primary School can fit frame mastic into the summer works.

Great Canney is about 4 miles south of Maldon, in Essex. Great Canney sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 644 places in Essex. Our London page has more on work in that area (34 miles or so).

Work on mastic joints is covered throughout CM3, for business premises of every kind. Close to Great Canney, our area also takes in Farther Howegreen (1 mile north-east), Cold Norton (1 mile east), Stow Maries (1 mile south), Howegreen (1 mile north) and Purleigh (1 mile north). Bigger towns within reach include Chelmsford (9 miles north-west), Basildon (11 miles south-west), Braintree (15 miles north), Brentwood (15 miles west), Maldon (4 miles north) and Canvey Island (11 miles south).

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Substrate edges that need repairing first
  • Leaks from above rather than through a joint
  • Materials that need asbestos testing before work

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think.

Where we work in Great Canney

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

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep a record of when each building was resealed
  • Make it easy for occupiers to report draughts
  • Share your contractor requirements early
  • Protect low-level joints in entrances

Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
