Mastic sealing for commercial buildings in Oakley

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. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints, and the failures we are asked to look at most are repeated reactive repairs to the same buildings and cracked, hardened mastic round windows on a block. Whoever orders the work in Oakley, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Places the size of Oakley typically have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we’re asked in Oakley

Do you cover business parks and estates near Oakley, such as Junction 5 Bates Industrial Estate?

Yes. Estates, retail parks and business parks around Oakley, Junction 5 Bates Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Is a smaller place like Oakley outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.

How long will the new sealant last?

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

How much does the work cost?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Signs you need mastic sealing in Oakley

Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.

Site and facilities staff are often the first to spot these:

  • Draughts at frames across a block
  • Estate-wide sealant that is simply worn out
  • Old repairs sealed over failed mastic
  • Water getting in round frames after rain

Property owners at sites such as Junction 5 Bates Industrial Estate (2.9 miles south of Oakley) can have mastic renewed between lettings.

Choosing a commercial sealant contractor

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Keep a record of when each building was resealed
  • Protect low-level joints in entrances
  • Include mastic in your cyclical inspections
  • Group repairs into a planned programme

Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Materials that need asbestos testing before work
  • Glazing that needs replacing
  • Failed window or door frames, which need a window contractor

If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Surfaces we seal

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

Planned mastic for Oakley portfolios

Central London is about 38 miles from Oakley. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Oakley included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you look after a block within reach of Princes Risborough station, which lies east of Oakley, frame and balcony mastic can be renewed on one programme. Schools and community buildings such as Mill Lane Community Primary School need frame and external mastic kept sound like any building.

Oakley is about 4 miles south-east of Thame, in Oxfordshire. Our applicators travel to Oakley for work on mastic joints, handled exactly as we handle every other area. Across Oxfordshire, 423 places are covered, including Oakley. Oxford is covered too, around 14 miles from Oakley.

Work on mastic joints is covered throughout OX39, for business premises of every kind. Among the streets we cover are Mill Lane, Beech Road and Oakley Lane, and sites on any of them can send details for a fixed quote. If your building is just outside Oakley, we cover Crowell (1 mile south-west), Kingston Blount (1 mile south-west), Crowell Hill (1 mile south-east), Aston Rowant (2 miles south-west) and Postcombe (3 miles west). Further afield, our area takes in Oxford (14 miles west), Didcot (15 miles south-west), Thame (4 miles north-west), Henley-on-Thames (12 miles south), Benson (10 miles south-west) and Headington Quarry (13 miles west).

How the job changes by surface

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.

Planned maintenance

Planned resealing replaces emergency callouts and spreads the work.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Work in places the size of Oakley is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  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.

Before we start on site

  • Move anything stored against the joints
  • Share the asbestos register for older buildings
  • Point out any areas we must not close
