Facade sealing for businesses in Broughton

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Broughton, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  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. 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. We walk the finished joints with you before handing over.

Before we start on site

  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints

Facade sealing in Broughton

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you are dealing with water coming in around window frames and draughts around frames and panels, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Broughton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Broughton, 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 photos and the programme and we will quote to suit.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Add perimeter sealant to planned maintenance checks
  • Report water ingress at frames as soon as it shows
  • Keep the sealant details on the building file
  • Insist on a full cut-out when joints are renewed

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading.

What affects the price in Broughton

A fixed quote reflects the actual work. It allows for:

  • How much existing material needs removing
  • Joint width, depth and condition
  • Site requirements such as inductions and permits
  • Any access equipment needed

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.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Whether an asbestos survey exists
  • Your programme or deadline
  • The type of building and who uses it
  • Specification clauses that apply

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Facade sealing around Broughton: points for this area

At about 67 miles from central London, Broughton is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

School extensions, at buildings such as Bishop Carpenter Church of England Aided Primary School, typically run to the summer holidays, mastic included. Further education sites such as Oxford and Cherwell Valley College (1.9 miles north-east of Broughton) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Broughton is about 2 miles south-west of Banbury, in Oxfordshire. Our applicators travel to Broughton for work on facade joints. Across Oxfordshire, 423 places are covered, including Broughton. Sites around Oxford have their own page, about 21 miles away.

What the job involves on each surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

What we are called out for in Broughton

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

Any of the following is a good reason to get the joints checked over:

  • Patch repairs that keep failing
  • Perimeter joints where frames meet the structure
  • Damp patches beside frames after rain
  • Cold air coming in at window perimeters

Older buildings in the area around Broughton, such as Broughton Castle (0.3 miles south-west of Broughton), need care when sealed: the product has to suit soft or historic materials.

Before you book anyone

  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • Are they CHAS accredited or on Constructionline?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Broughton: questions and answers

Do you take on work at healthcare sites like The Horton General Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Broughton too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. When you call the office on 01277 525 020 or send details through our quote form, describe the access, and we will agree the approach together.

Do you run new sealant over the existing bead?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

Can staff carry on working while you’re here?

Typically, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
