Facade sealing in Northway: the local picture
Rainfall across the South East, Northway included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. A 2-mile radius around Northway takes in a good number of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
University estates such as Oxford Brookes University Marston Road Site, 0.8 miles south-west of Northway, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When units on a site such as Shotover Trading Estate, 1.7 miles to the south-east of Northway, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at colleges like Oxford Sixth Form College, 1.9 miles south-west of Northway, tend to run to term dates, so the mastic is planned tightly.
Northway is about 1 mile north of Oxford, in Oxfordshire. We cover commercial sites throughout Northway, for single jobs and planned programmes alike. Across Oxfordshire, 423 places are covered, including Northway.

What else we do in Northway
How the job changes by surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints, not the framing or glazing itself.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.
Building owners, agents and FMs in Northway
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Avoid harsh cleaners on facade sealant
- Don’t wait for a second leak before calling
- Never let anyone seal over old sealant
- Check that rainwater leaves the facade the way it was designed to
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards using a matching sealant.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.
When to bring in a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Our process
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. If neighbouring businesses or buildings around Northway need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
FAQs: Northway
Will you plan work around the academic year at somewhere like Oxford Brookes University Marston Road Site?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Northway off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Do you seal facades in winter?
Rain and frost can pause external sealing. We plan for weather and keep you updated as the work goes on.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do we need an asbestos check before resealing?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
Why it’s worth doing now in Northway
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
