Facade sealing in Hawkley

We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. The enquiries we see most involve gaps between rainscreen or cladding panels and hard, chalky sealant that no longer flexes, on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints. A specialist sealant contractor works differently from a general builder: in Hawkley, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Hawkley 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 normally what’s needed.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Hawkley

The wrong product causes its share of trouble: 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.

These are often picked up first by site or facilities staff:

  • Perimeter joints where frames meet the structure
  • Gaps between rainscreen or cladding panels
  • Weathered facade joints that have lost their grip
  • Damp patches beside frames after rain

Extensions at sites like Petersfield Community Hospital (to the south of Hawkley) usually sit beside working departments, and the mastic follows strict access rules.

Choosing a commercial sealant contractor

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Hawkley can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed 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. We go over the completed work with you before leaving.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use
  • Confirm the product named in the specification

Ask for a quote

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Different surfaces, different methods

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them to the correct depth.

Hawkley: questions and answers

Would you work within a site like Petersfield Community 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.

Can you work at a site such as Ham Barn Business Park, by Hawkley?

Yes. Estates, retail parks and business parks around Hawkley, Ham Barn Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Facade sealing in Hawkley: the local picture

Hawkley 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 external mastic is timed for workable conditions and agreed with the site manager. Hawkley lies roughly 48 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

New units and refits on sites such as Ham Barn Business Park, 1.5 miles east of Hawkley, need their panel and perimeter joints sealed to the specification.

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

After the work

Once the work is signed off, a little attention goes a long way:

  • Keep sills, gutters and drainage paths clear
  • Plan facade sealing alongside redecoration
  • Never let anyone seal over old sealant
  • Check the asbestos register before old mastic is disturbed

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

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.
