Mastic sealing across Chegworth

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Mastic sealing for commercial buildings in Chegworth

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 communal kitchens and washrooms, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are a mix of products and colours from past repairs and open joints in brickwork or panels. Most enquiries from Chegworth start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Chegworth, 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.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Why deal with it now?

Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. One visit to deal with every failing joint makes more sense than several trips to a place like Chegworth, rather than one at a time. Photos of every joint help us quote for the whole job.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What you get with us

  • Clear, fixed quotes
  • Constructionline member for supplier checks
  • One phone line for London, the South East and Scotland
  • CHAS accredited

See our cost guide and how we’re accredited.

What sets the cost

We price every job individually. The main factors are:

  • Whether the work must be split into stages
  • Travel to remote or island sites
  • How much there is to seal
  • Site requirements such as inductions and permits

Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Your programme or deadline
  • Clear photos of the problem areas

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or send details through our quote form if you’d rather talk the job through.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Chegworth, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Agree which areas must stay open

Chegworth: questions and answers

Does your area include sites such as Roebuck Business Park, near Chegworth?

Yes, sites like Roebuck Business Park are within our area, along with the rest of Chegworth. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Chegworth outside your area?

No. Places such as Chegworth are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can people stay in the building while you reseal?

The work is planned around occupiers. We agree the programme so you can notify occupiers and communal access is kept open.

What if the old mastic contains asbestos?

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

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

How much does the work cost?

Each job is quoted on its own details. For yours, ring 01277 525 020 or email us.

Frames, entrances and external joints in Chegworth

Rainfall across the South East, Chegworth included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Chegworth lies roughly 37 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.

Property owners at sites such as Roebuck Business Park (1 mile east of Chegworth) can have mastic renewed between lettings. Schools and community buildings such as Harrietsham Church of England Primary School need frame and external mastic kept sound like any building. Owners of student blocks near Canterbury Christ Church University, 2 miles to the north-east of Chegworth, can schedule frame and external mastic for the summer vacation.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Communal areas

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

Maintenance after handover

To get the most from the new sealant:

  • Track which buildings were done and when
  • Ask residents or tenants to report leaks and draughts early
  • Group repairs into a planned programme
  • Check sealant joints during planned building inspections

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.
