Mastic sealing for New Hinksey sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Keeping the joints sound
For the best life from the joints:
- Start inspections with the most exposed faces
- Keep bins and bikes away from communal door frames
- Make mastic part of routine maintenance checks
- Make it easy for occupiers to report draughts
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
How we handle mastic sealing in New Hinksey
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. We work on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and repeated reactive repairs to the same buildings. A single leaking joint is often how a building in New Hinksey first comes to us: we look at the rest while we are there and tell you what we find.
Older buildings and conversions around places like New Hinksey mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
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’re clear about what is covered before work starts.

Cost factors for mastic joints
We price every job individually. The things that drive the figure:
- The site’s rules and procedures
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- How much there is to seal
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- Anything awkward about access or site hours
- The asbestos register, for older buildings
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. For buildings in places like New Hinksey, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.
Why appoint us
- One phone line for London, the South East and Scotland

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Frames that are rotten, warped or broken
- Misted or failed double-glazed units
- Masonry that has broken away beside the joint
Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

FAQs: New Hinksey
Do you work for managing agents with blocks near Oxford station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Is Osney Mead Industrial Estate, near New Hinksey, within your area?
Yes. Our area takes in New Hinksey and its surroundings, with estates and business parks such as Osney Mead Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Looking after buildings in and around New Hinksey
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first. New Hinksey lies roughly 52 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
Landlords with units on estates such as Osney Mead Industrial Estate (to the north-west of New Hinksey) can bring frame, door and external mastic across several units into one programme. If you look after a block within reach of Oxford station, 1.3 miles to the north-west of New Hinksey, frame and balcony mastic can be renewed on one programme. Schools and community buildings such as New Hinksey Church of England Primary School need frame and external mastic kept sound like any building.
