About our facade sealing in Avon Castle

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. Most enquiries involve previous reseals run over old sealant and leaks at window and door perimeters, on shopfront frames, perimeter joints where frames meet the structure and window and door perimeters. Looking for mastic applicators who cover Avon Castle? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Construction in and around smaller places such as Avon Castle is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

A 12-month guarantee applies to all our work in Hampshire. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we will come back to it.

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. One visit to deal with every failing joint makes more sense than several trips to a place like Avon Castle, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • 12 months’ guarantee on every job
  • Clear, fixed quotes
  • Coloured sealants to suit the setting, where available
  • Fully insured, including public liability cover

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Damp caused by condensation inside the building
  • Installing or repairing glazing systems
  • Joints too narrow for the movement they take, which need redesign

If you’re not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in Avon Castle

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

When to bring in a specialist

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 where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Building owners, agents and FMs in Avon Castle

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Avon Castle can form part of a wider programme.

Signs you need facade sealing in Avon Castle

Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

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

  • Discoloured or dirty facade joints
  • Weathered joints at frame-to-structure perimeters
  • Hard, chalky sealant that no longer flexes
  • Water coming in around window frames

For a contractor at a hotel such as St Leonards Hotel (1.4 miles west of Avon Castle), the mastic often has to be finished before a reopening date.

Before you book anyone

  • Their approach to joint depth and backing
  • How long is the guarantee, and what does it include?
  • Whether primer will be used where the manufacturer specifies it
  • Will CSCS-carded applicators be on site?

Our contractor checklist

Facade sealing around Avon Castle: how the place shapes the job

The area within 2 miles of Avon Castle holds a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Rainfall across the South East, Avon Castle included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

On a healthcare site such as St Leonards Hospital, 2.3 miles west of Avon Castle, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Recladding or extending a unit at a site like Millstream Trading Estate, 1.2 miles to the north-east of Avon Castle, brings panel joints and frame perimeters into the programme.

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure.
