Facade sealing across Swerford

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Facade sealing in Swerford, done properly

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you are dealing with old perimeter mastic that has dried out and gaps between rainscreen or cladding panels, we can put it right. Most enquiries from Swerford start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Swerford can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Commercial clients in Swerford

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

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.

Quoting for work in Swerford

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • The size and state of each joint
  • Whether the work must be split into stages
  • The total length or number of joints
  • How accessible the joints are

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Before you send an enquiry

We can often quote from photos and a few details. It helps to include:

  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older
  • The type of building and who uses it
  • Anything awkward about access or site hours

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

How the job changes by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

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.

Building and refurbishing in Swerford

Swerford is about 67 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Swerford sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.

Sites around Swerford get mastic sealed to the drawings and the programme, nothing improvised. Window perimeters and facade joints around Swerford need correct width, depth and backing rod as much as a neat finish.

Swerford is about 7 miles south-west of Banbury, in Oxfordshire. Businesses, contractors and managing agents in Swerford use us for work on facade joints.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Render or concrete edges that have broken away
  • Installing or repairing glazing systems
  • Damp caused by condensation inside the building

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

  • Window and door perimeters
  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Stone and brick facade joints
  • Coping and flashing joints
  • Shopfront frames

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Swerford need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits
