How we handle facade sealing in Balls Cross

Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. The enquiries we see most involve failed seals around shopfront and entrance frames and staining on stone next to old sealant, across coping and flashing joints, stone and brick facade joints and shopfront frames. A single leaking joint is often how a building in Balls Cross 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.

For a site near Balls Cross, 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.

Our process

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 Balls Cross may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Send any specification or drawings in advance

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Damaged frames that need replacing
  • Water getting in through cracked render or porous masonry
  • Joints whose design needs changing by the specifier

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

Where we work in Balls Cross

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

After the work

Regular inspection catches problems early. Specifically:

  • Plan facade sealing alongside redecoration
  • Keep the sealant details on the building file
  • Never let anyone seal over old sealant
  • Keep pressure washers away from fresh sealant

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones behind the facade.

Why act early in Balls Cross

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. One visit to deal with every failing joint makes more sense than several trips to a place like Balls Cross. Photos of every joint help us quote for the whole job.

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

Your questions answered

Can you keep pace with our programme in Balls Cross?

Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Balls Cross too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is it fine to apply new sealant on top of old?

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

Can you work to our specification?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

How the job changes by surface

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

Facade sealing in Balls Cross: the local picture

Balls Cross is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Balls Cross is about 39 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

With historic properties like Petworth House (to the south of Balls Cross) in the area, refurbishment work often meets old masonry that needs compatible sealants. New units and refits on sites such as Colhook Industrial Park. (to the west of Balls Cross) need their panel and perimeter joints sealed to the specification.
