Mastic sealing in Deddington
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on communal entrances and stairwells, shopfronts below residential blocks and external wall and movement joints, and the usual reasons a site gets in touch are old repairs sealed over failed mastic and mastic failing across several blocks on an estate. Looking for mastic applicators who cover Deddington? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Owners and agents with buildings around smaller places such as Deddington tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after buildings in and around Deddington
Deddington sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. Deddington is about 62 miles from central London. 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.
Landlords with units on estates such as Station Yard Industrial Estate (to the north of Deddington) can bring frame, door and external mastic across several units into one programme. If your remit includes a building such as Deddington Church of England Primary School, frame and door mastic can be programmed for the holidays. Historic properties like Broughton Castle (to the north-west of Deddington) show the age of some local stock, where frame mastic must suit soft brick or stone.
Deddington is about 6 miles south of Banbury, in Oxfordshire. Across the OX15 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Oxfordshire, 423 places are covered, Deddington among them. We also cover Oxford, around 16 miles from Deddington.

Local landmarks in Deddington

What we can’t put right
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Leaks through the frame itself rather than the perimeter
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Water coming in from the roof or rainwater goods
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Questions we are asked in Deddington
Do you cover business parks and estates near Deddington, such as Station Yard Industrial Estate?
Yes. Estates, retail parks and business parks around Deddington, Station Yard Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is Deddington off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Leave it or put it right?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Halls, stores and units around places like Deddington may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What the job involves on each surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- The size and state of each joint
- How much existing material needs removing
- The total length or number of joints
- Any access equipment needed
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
What we need to price the job
Diagnosis starts before we arrive. Let us know:
- Whether an asbestos survey exists
- Any specification or named product
- A wide shot and a close-up of the area
- Approximate linear metres or a joint schedule
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email drawings and photos to discuss it first.
