Questions we are asked in Swinford

Is Oakfields Industrial Estate, near Swinford, within your area?

Yes. Our area takes in Swinford and its surroundings, with estates and business parks such as Oakfields Industrial Estate included. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

Can work in a care setting near Swinford go ahead while residents are there?

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Can you seal joints high up on a block?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Does weather matter for sealant work?

It can, when the joints are outside. 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.

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.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Mastic sealing in Swinford

Across Swinford and the rest of Oxfordshire, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. We work on communal entrances and stairwells, window and door perimeters on blocks and shopfronts below residential blocks, and the usual reasons a site gets in touch are brittle perimeter mastic across a building and worn sealant at communal door frames. For commercial sealant work in Swinford, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Rural conversions near places like Swinford often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

For owners and agents in Swinford

At about 57 miles from central London, Swinford is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Swinford included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first.

Landlords with units on estates such as Oakfields Industrial Estate, 0.9 miles to the west of Swinford, can bring frame, door and external mastic across several units into one programme. Student accommodation around universities such as Azad University in Oxford, 0.7 miles south of Swinford, is normally managed block by block, which suits a planned mastic programme.

Swinford is about 6 miles west of Oxford, in Oxfordshire. Businesses, contractors and managing agents in Swinford can call on us for mastic joints. Swinford is one of 423 places in Oxfordshire on our list for mastic joints. There’s a separate page for Oxford, about 6 miles away.

Commercial sites across OX29 are covered for mastic joints. We also cover Eynsham (1 mile north-west), Farmoor (1 mile south-east), Cassington (1 mile north-east), Filchampstead (2 miles south) and Wytham (2 miles east) for mastic joints. Bigger towns within reach include Oxford (6 miles east), Didcot (12 miles south-east), Bicester (12 miles north-east), Abingdon-on-Thames (7 miles south-east), Witney (6 miles west) and Carterton (10 miles west).

A little further out are Oxford Castle and earlier settlement remains (4.4 miles east) and Oxford Bus Museum (3.6 miles north). The countryside around Swinford includes Cumnor Hill and Hook Meadow and The Trap Grounds.

Leave it or put it right?

Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. Halls, stores and units around places like Swinford may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why us?

  • RAL and finish matching where the product range allows
  • Over 20 years of commercial sealing
  • Standard and matched colours in many product ranges
  • A fixed quote before work starts

See what affects the cost and how we’re accredited.

Keeping the joints sound

For the best life from the joints:

  • Make mastic part of routine maintenance checks
  • Have the asbestos survey to hand for older buildings
  • Group repairs into a planned programme
  • Keep a record of when each building was resealed

Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.

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

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Frames that are rotten, warped or broken
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Broken glass or failed sealed units

If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think.

Where we work in Swinford

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

When to call us in Swinford

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

It’s worth sending us details if you spot any of the following:

  • Complaints coming in block by block
  • Window mastic that has split and shrunk
  • Leaks at window and door perimeters
  • Movement joints with sealant missing

If you are responsible for a building such as Church of St Leonard, frame and door mastic needs the same attention as any other property.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled
  • Will RAMS and insurance details be available?
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

How the quote is worked out

To price the job, we consider:

  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • How much existing material needs removing

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Details that help us quote

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

  • Photos of the joints, close up and from further back
  • The postcode of the building
  • The product your specification calls for
  • The asbestos register, for older buildings

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or use the quote form.
