How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. For work around Bledington, we aim to finish in one 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. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • Flag any permit to work we will need

Advice

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Look at the sunniest and most exposed elevations first
  • Have the asbestos survey to hand for older buildings
  • Plan resealing building by building rather than complaint by complaint
  • Include mastic in your cyclical inspections

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

What affects the price in Bledington

A fixed quote reflects the actual work. It takes account of:

  • Distance, for remote addresses
  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits

A quote for mastic joints depends on quantities, condition and access. Call for a quote.

What we need to price the job

However big the job, these details speed things up:

  • The product your specification calls for
  • How the joints are reached, and at what height
  • A wide shot and a close-up of the area
  • Your programme or deadline

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email a schedule or drawings with what you know.

Frames, entrances and external joints in Bledington

Rainfall across the South East, Bledington included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

With historic buildings such as Chastleton House, 4 miles to the north of Bledington, in the wider area, owners of older properties around Bledington should expect mastic to need a product that suits old masonry. For a school such as Bledington Primary School, perimeter mastic on windows and doors is a holiday job.

Bledington is about 10 miles north of Carterton, in Oxfordshire. Businesses, contractors and managing agents in Bledington use us for work on mastic joints, as part of our coverage of Oxfordshire. Bledington is one of 423 places in Oxfordshire on our list. We also cover Oxford, some 20 miles away.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Failed window or door frames, which need a window contractor
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Substrate edges that need repairing first

If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.

Surfaces we seal

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

Bledington: questions and answers

Do you work for managing agents with blocks near Kingham station?

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

Will you price a mastic programme across our Bledington portfolio?

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

Will you just go over the old sealant?

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

How many days will you need on site?

It depends on the scope, though a typical visit typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What paperwork can you provide?

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 hold CHAS accreditation and Constructionline membership.

Is mastic sealing guaranteed?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Signs you need mastic sealing in Bledington

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

These are often picked up first by site or facilities staff:

  • A mix of products and colours from past repairs
  • Brittle perimeter mastic across a building
  • Damp patches beside frames
  • Worn sealant at communal door frames

Churches, halls and community buildings such as Church of St Leonard are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

What to look for in a quote

  • Their approach to joint depth and backing
  • Whether primer will be used where the manufacturer specifies it
  • Whether their applicators hold CSCS cards
  • Whether old or failed sealant will be cut out, not overlaid
