How we handle mastic sealing in New Yatt
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you’re dealing with no planned programme for sealant and movement joints with sealant missing, we can put it right, whatever the surface. Whoever orders the work in New Yatt, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like New Yatt, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Our 12-month guarantee is about workmanship, not 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.

Different surfaces, different methods
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. Rural sites near New Yatt may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Flag any permit to work we’ll need
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Materials that need asbestos testing before work
- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods

Can you quote for a block close to Finstock station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you plan resealing across several buildings?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Mastic sealing around New Yatt: how the place shapes the job
Rainfall across the South East, New Yatt 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. At about 62 miles from central London, New Yatt is within reach of the capital. 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.
Historic properties like Minster Lovell Hall, 3.4 miles to the west of New Yatt, show the age of some local stock, where frame mastic must suit soft brick or stone. Site managers at schools like North Leigh Church of England (Controlled) School can fit frame mastic into the summer works.
New Yatt is about 2 miles north-east of Witney, in Oxfordshire. Commercial clients in New Yatt use us for work on mastic joints, as part of our coverage of Oxfordshire. New Yatt is one of 423 places we cover in Oxfordshire for mastic joints. Oxford is covered too, around 11 miles from New Yatt.
Work on mastic joints is covered throughout OX29, whatever the building. Among the streets we cover are New Yatt Road and New Yatt Lane. Close to New Yatt, our area also takes in North Leigh (1 mile east), Poffley End (1 mile west), Delly End (1 mile west), Hailey (2 miles west) and East End (2 miles north-east).

What’s near New Yatt
We work on buildings around The King's School, Wood Green School and The Saddlers Arms and the streets around them. The nearest railway station is Finstock station, roughly 2.7 miles north of the centre. Nearby you’ll also find Cogges Manor Farm Museum (2.3 miles south-west). Not far away are Blenheim Farm.
What happens if it’s left?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. Around New Yatt, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Do you need mastic sealing in New Yatt?
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Site and facilities staff are often the first to spot these:
- A mix of products and colours from past repairs
- Cracked, hardened mastic round windows on a block
- Complaints coming in block by block
- Movement joints with sealant missing
Buildings close to stations like Finstock station (2.7 miles north of New Yatt) are often flats over shops, with frame mastic to keep sound.
