Facade sealing for Somerley sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Facade sealing in Somerley

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. The enquiries we see most involve failed seals around shopfront and entrance frames and patch repairs that keep failing, across shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints. Most enquiries from Somerley 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 Somerley, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.

When it isn’t the sealant

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

  • Installing or repairing glazing systems
  • Cracked or spalling substrates that need repair before sealing
  • Damp caused by condensation inside the building

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

What we are called out for in Somerley

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.

Typical triggers for a call:

  • Weathered facade joints that have lost their grip
  • Staining on stone next to old sealant
  • Water coming in around window frames
  • Cold air coming in at window perimeters

When a school such as Birdham CE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Before you book anyone

  • How joint depth will be controlled
  • Will failed sealant be removed rather than covered?
  • How they handle RAMS and site documents
  • Which product they’ll use, and why it suits the joint

Our contractor checklist

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Somerley need work, visits can be combined. 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 and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

Getting the site ready

  • Flag any permit to work we’ll need
  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed

Your questions answered

Would you work within a site like St Richard's Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is a smaller place like Somerley outside your area?

Not at all. Somerley is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

How soon can the area be used again?

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

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.

What sets the cost

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

  • Travel to remote or island sites
  • The product specified
  • The site’s rules and procedures
  • Whether old sealant has to be cut out first

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode

For a fixed quote, call 01277 525 020 or send details through our quote form. You can also send details through our quote form.

Leave it or put it right?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Converted and older buildings near places like Somerley tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Facade sealing in Somerley: the local picture

Somerley sits close to the coast, within about 2 miles. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Somerley included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

For contractors refurbishing units at places like Enborne Business Park, 2.8 miles south-east of Somerley, the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as St Richard's Hospital, 5.2 miles to the north-east of Somerley, 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.

Somerley is about 4 miles north-west of Selsey, in West Sussex. Somerley sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Somerley is one of 373 places in West Sussex on our list. For work in that direction, see our Portsmouth page.
