Facade sealing in Elvendon, done properly

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We build that into the programme and tell you if the forecast changes the plan. If you’re dealing with discoloured or dirty facade joints and old perimeter mastic that has dried out, we can help, whatever the surface. A single leaking joint is often how a building in Elvendon first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Elvendon, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

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

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we will tell you honestly before you book.

What we seal

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

Leave it or put it right?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Older rural buildings around Elvendon move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why us?

  • Work carried out by CSCS-carded applicators
  • CHAS accredited contractor
  • Colour options checked against the specified product
  • Clear, fixed quotes

Looking after the joints

Regular inspection catches problems early. In particular:

  • Confirm the survey covers external sealants in older buildings
  • Inspect facade joints on a regular cycle
  • Share access with other external trades
  • Record the product and colour used on each elevation

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

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.

For managing agents and facilities managers

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Building and refurbishing in Elvendon

Central London is about 43 miles from Elvendon. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. The South East is one of the drier 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.

Projects at schools like The Oratory Preparatory School work to term dates, so mastic is programmed tightly. With historic properties like Basildon Park (to the south-west of Elvendon) in the area, refurbishment work often meets old masonry that needs compatible sealants.

How the job changes by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Elvendon may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.
