Facade sealing near Headington

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Cost factors for facade joints

Each job is priced on its own details. The main factors are:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The type of building and who uses it
  • When you need the work done
  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area

Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, phone 01277 525 020 or email a schedule or drawings.

Facade sealing in Headington, done properly

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. We work on coping and flashing joints, perimeter joints where frames meet the structure and stone and brick facade joints, and what we’re called in for most is gaps between rainscreen or cladding panels and weathered joints at frame-to-structure perimeters. Facilities teams, main contractors and managing agents in Headington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Building work in places the size of Headington 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 spell out the cover before we begin.

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Cracked or spalling substrates that need repair before sealing
  • Damp caused by condensation inside the building
  • Providing access systems for the work

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly.

What we seal

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

General trades versus 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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them to the correct depth.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Several jobs near Headington can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  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. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Tell us which areas need to stay in use
  • Let us know about inductions and permits
  • Let building users know which areas are affected

Facade sealing around Headington: how the place shapes the job

Headington is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. A 2-mile radius around Headington takes in several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.

Building work at universities like Oxford Brookes University, 0.9 miles to the south-west of Headington, is often timed for the summer, mastic included. Further education sites such as Oxford Sixth Form College, 2 miles to the south-west of Headington, are extended and refurbished from time to time, with mastic often programmed into the summer break. Recladding or extending a unit at a site like Shotover Trading Estate (1.1 miles south-east of Headington) brings panel joints and frame perimeters into the programme.
