Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Chinnor can sit alongside others in a wider programme.
About our construction mastic in Chinnor
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal areas can normally carry on while the outside waits. If you have sanitary sealant damaged by following trades and cracks opening in caulked internal joints, we can put it right, on internal decorators’ caulk, sanitary and kitchen joints and floor and skirting junctions alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Chinnor is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places like Chinnor, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common problems we fix in Chinnor
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
It’s worth sending us details if you spot any of the following:
- New external sealant already peeling away
- Inconsistent sealant finishes from plot to plot
- Bath and shower joints scraped during the final clean
- Internal caulk splitting as the building dries out
Units on estates such as Junction 5 Bates Industrial Estate, 2.9 miles to the south of Chinnor, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Questions we’re asked in Chinnor
Is a smaller place like Chinnor outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Junction 5 Bates Industrial Estate, by Chinnor?
Yes. Estates, retail parks and business parks around Chinnor, Junction 5 Bates Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Tell us what records you need and we will confirm with the quote.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Will you stick to the specified products?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Ask for joint and product checks before the package is urgent
- Ask cleaners to use soft cloths around fresh sealant
- Release areas for mastic once other trades have finished in them
- Note which sealant went where at handover
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades, so protecting sealed areas matters.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.
Why act early in Chinnor
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal, which is a much smaller cost. We’ll say so if a frame itself is the problem. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Why us?
- Coloured sealants to suit the setting, where available

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
New build and refits around Chinnor
Chinnor sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 38 miles from Chinnor. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
Projects at schools like St Andrew's Church of England Primary School work to term dates, so mastic is programmed tightly. For a contractor working at a hospital such as Thame Community Hospital, which lies north-west of Chinnor, perimeter and facade sealing is planned around patients and deliveries.
Chinnor is about 8 miles north-west of High Wycombe, in Oxfordshire. We send applicators to Chinnor for mastic packages, handled exactly as we handle every other area. Chinnor is one of 423 places we cover in Oxfordshire. Oxford is covered too, some 14 miles away.

Diagnose, treat, sign off

Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Work in places the size of Chinnor is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
