Facade sealing across Westcott Barton

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

How we handle facade sealing in Westcott Barton

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. We work on stone and brick facade joints, window and door perimeters and cladding panel joints, and the failures we’re asked to look at most are old perimeter mastic that has dried out and failed sealant on precast panel joints. Most enquiries from Westcott Barton 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.

Conversions of older rural buildings near smaller places such as Westcott Barton bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

A 12-month guarantee applies to all our work in Oxfordshire. If an installation problem shows up, call 01277 525 020 or email drawings and photos and we will arrange a return visit.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Westcott Barton can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Advice

Do you need facade sealing in Westcott Barton?

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Look out for the following:

  • Damp patches beside frames after rain
  • Hard, chalky sealant that no longer flexes
  • Weathered joints at frame-to-structure perimeters
  • Discoloured or dirty facade joints

School extensions, at buildings such as Middle Barton Primary School, typically run to the summer holidays, mastic included.

What to look for in a quote

  • The named product and why it was chosen
  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?
  • Their pre-qualification and accreditations

Our contractor checklist

After the work

Keep the joints in good shape with a few simple steps:

  • Share access with other external trades
  • Check the asbestos register before old mastic is disturbed
  • Brief window cleaners about newly sealed joints
  • Walk the elevations once or twice a year

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.

Mastic packages on Westcott Barton sites

Rainfall across the South East, Westcott Barton included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. At about 62 miles from central London, Westcott Barton is within reach of the capital. 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.

New units and refits on sites such as Enstone Airfield Industrial Estate (to the west of Westcott Barton) need their panel and perimeter joints sealed to the specification.

Westcott Barton: questions and answers

Is a smaller place like Westcott Barton outside your area?

No. Places such as Westcott Barton are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can the mastic package for our job in Westcott Barton follow the site programme?

Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Providing access systems for the work
  • Render or concrete edges that have broken away
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

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

What sets the cost

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

  • Whether the work must be split into stages
  • Any access equipment needed
  • Joint width, depth and condition
  • Removal of failed or old sealant

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Send us:

  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them
  • Clear photographs of the problem areas
  • The type of building and who uses it

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
