Facade sealing in Cowley, done properly
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. The enquiries we see most involve perimeter sealant that has split or peeled away and air leaks through failed facade joints, across coping and flashing joints, perimeter joints where frames meet the structure and stone and brick facade joints. Searching for sealant specialists in Cowley? We’ve been sealing commercial buildings since 2005.
Building work in places the size of Cowley is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Mastic packages on Cowley sites
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. A 2-mile radius around Cowley takes in plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
Work at a hotel such as Mercure Oxford Hawkwell House Hotel (to the west of Cowley) tends to be programmed around bookings, mastic included. Further education sites such as Oxford Sixth Form College (2.1 miles north-west of Cowley) are extended and refurbished from time to time, with mastic often programmed into the summer break. New units and refits on sites such as Templars Shopping Park (less than half a mile west of Cowley) need their panel and perimeter joints sealed to the specification.

You will then get a fixed price for the work.

- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.

Cowley: questions and answers
Will you take on work at estates like Templars Shopping Park, close to Cowley?
Yes. Our area takes in Cowley and its surroundings, with estates and business parks such as Templars Shopping Park included. A few photos and the unit address let us price the work.
Will you plan work around the academic year at somewhere like Oxford Brookes University?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What type of sealant goes on window perimeters?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Do you cover Cowley?
Yes. We take on work across Cowley.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Site requirements such as inductions and permits
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Phasing around occupants
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Your programme or deadline
- The type of building and who uses it
- Any specification or named product
- Whether an asbestos survey exists
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Why deal with it now?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What the job involves on each surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex without tearing.
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, as the specification sets out.
