Facade sealing in Cassington
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Most enquiries involve previous reseals run over old sealant and cladding panel joints that have opened up, across stone and brick facade joints, window and door perimeters and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Cassington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Cassington bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

What the job involves on each surface
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints rather than the system it surrounds.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.
New build and refits around Cassington
Central London is about 57 miles from Cassington. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Cassington 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, which is why external dates are agreed with the site manager.
On a healthcare site such as Radcliffe Infirmary, 4.1 miles south-east of Cassington, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors refurbishing units at places like Oasis Business Park (1.9 miles south-west of Cassington), the mastic covers cladding panels, roller-door and window perimeters. Building work at universities like University Field Station (to the south-east of Cassington) is often timed for the summer, mastic included.
Cassington is about 6 miles north-west of Oxford, in Oxfordshire. Anywhere in OX29, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 423 places in Oxfordshire, large and small. For work in that direction, see our Oxford page, about 6 miles away.

When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Quoting for work in Cassington
Each job is priced on its own details. The things that drive the figure:
- Joint width, depth and condition
- Working within restricted access windows
- How much there is to seal
- Any access equipment needed
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- When you need the work done
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or send details through our quote form.
When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Damp caused by condensation inside the building
- Specialist high-level access methods
- Installing or repairing glazing systems
If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think before you book.

FAQs: Cassington
Is Cassington too far out for you?
Not at all. Cassington is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is hospital work, at somewhere like Radcliffe Infirmary, something you do?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Do you use silicone for external joints?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email us. Include photographs or drawings if you have them.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Cassington may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.

Preparing the site
- Explain the parking and delivery arrangements
