How we handle mastic sealing in Clavering

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are estate-wide sealant that is simply worn out and water getting in round frames after rain. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Clavering it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Clavering, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Why act early in Clavering

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. Halls, stores and units around places like Clavering may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • CSCS-carded applicators
  • CHAS accredited
  • One phone line for London, the South East and Scotland
  • Colour agreed before work starts

What the job involves on each surface

Communal areas

Low-level communal joints get damaged more than most and tend to fail first.

External movement joints

Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.

Clavering: questions and answers

Do you cover business parks and estates near Clavering, such as Funstons Commercial Centre?

Yes. We cover Clavering and the area around it, including industrial estates, business parks and retail parks such as Funstons Commercial Centre. Photos and a short description are enough for a first look.

We manage a building near Newport (Essex) station. Can you help?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Do you do block-wide mastic programmes?

Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.

How do you handle work on occupied blocks?

The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Whether old sealant has to be cut out first
  • The product specified
  • Whether the work must be split into stages
  • The site’s rules and procedures

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • Clear photos of the problem areas
  • What the building is and how it’s used

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send details through our quote form.

Blocks and managed buildings in Clavering

Rainfall across the South East, Clavering included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Central London is about 34 miles from Clavering. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.

If your remit includes a building such as Clavering Primary School, frame and door mastic can be programmed for the holidays. If you are responsible for a building such as Church of St Mary and St Clement, frame and door mastic needs the same attention as any other property. Blocks of flats and mixed-use buildings often cluster around stations such as Newport (Essex) station (3.3 miles east of Clavering) and their window and balcony mastic tends to age at the same rate across a building.

Clavering is about 6 miles south-west of Saffron Walden, in Essex. Businesses, contractors and managing agents in Clavering can call on us for mastic joints. Clavering is one of 644 places in Essex on our list for mastic joints. Sites around London have their own page, roughly 34 miles from Clavering.

Keeping the joints sound

After handover, these steps help:

  • Keep bins and bikes away from communal door frames
  • Have the asbestos survey to hand for older buildings
  • Avoid piecemeal callouts where you can
  • Look at the sunniest and most exposed elevations first

Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges, and note the building and elevation.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Rural sites near Clavering may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
