Facade sealing in Fifield: the local picture

Fifield sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

For contractors refurbishing units at places like Wychwood Business Centre, 2.2 miles to the east of Fifield, the mastic covers cladding panels, roller-door and window perimeters.

Fifield is about 7 miles north of Carterton, in Oxfordshire. We cover Fifield and the rest of Oxfordshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 423 places in Oxfordshire, from busy centres to rural villages. There’s a separate page for Oxford, about 20 miles away.

Commercial sites across OX7 are covered for facade joints. We cover commercial and managed buildings on High Street, Church Street and The Green and the roads nearby. Just outside Fifield, we also work in Idbury (1 mile north), Milton-under-Wychwood (2 miles east), Foscot (2 miles north), Fulbrook (4 miles south) and Little Barrington (4 miles south-west). A short drive away, we cover Witney (9 miles south-east), Carterton (7 miles south), Faringdon (15 miles south), Chipping Norton (7 miles north-east), Woodstock (13 miles east) and Cogges (9 miles south-east).

Facade sealing in Fifield

We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you are dealing with facade joints cracked through the middle and perimeter joints where frames meet the structure, we can help. Most enquiries from Fifield 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.

For a site near Fifield, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Looking after the joints

Once the work is signed off, these steps help:

  • Clear debris that holds water against joints
  • Add perimeter sealant to planned maintenance checks
  • Brief window cleaners about newly sealed joints
  • Never let anyone seal over old sealant

Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed.

Coordinate facade sealing with other external works. One set-up for several trades saves money.

Commercial clients in Fifield

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

When to call us in Fifield

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

If one of these sounds familiar, it’s time for a closer look:

  • Gaps between rainscreen or cladding panels
  • Hard, chalky sealant that no longer flexes
  • New sealant peeling off old mastic
  • Weathered joints at frame-to-structure perimeters

Hospital estates such as Moore Cottage Hospital (4.6 miles west of Fifield) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Before you book anyone

  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • Their plan for phasing and protecting the area
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Smaller jobs around Fifield can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  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.

Preparing the site

  • Send any specification or drawings in advance
  • Move anything stored against the joints
  • Flag any permit to work we’ll need

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email us.

Cost factors for facade joints

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

  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • How much there is to seal
  • Distance, for remote addresses

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

However big the job, these details speed things up:

  • The postcode of the building
  • Access details, including height
  • What the building is and how it’s used
  • Any dates the work must fit around

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or send photos by email with what you know.

Surface by surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex as the frame moves.

Questions about Fifield

Can you take on a job at a hospital such as Moore Cottage Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Do you cover business parks and estates near Fifield, such as Wychwood Business Centre?

Yes, sites like Wychwood Business Centre are within our area, along with the rest of Fifield. A few photos and the unit address let us price the work.

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
