Facade sealing near Horney Common

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Facade sealing in Horney Common, done properly

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have old perimeter mastic that has dried out and unsightly perimeter sealant on a visible elevation, we can help, on coping and flashing joints, perimeter joints where frames meet the structure and stone and brick facade joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Horney Common, that means joint design, primers and backing rod as standard.

For a site near Horney Common, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Doing it in-house

Certain joints really need a specialist: 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Do you need facade sealing in Horney Common?

Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.

What tends to prompt an enquiry:

  • Weathered joints at frame-to-structure perimeters
  • Hard, chalky sealant that no longer flexes
  • Air leaks through failed facade joints
  • Failed sealant on precast panel joints

On a healthcare site such as Uckfield Community Hospital, which lies south of Horney Common, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

What your quote should include

  • How the existing material will be dealt with
  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Questions we are asked in Horney Common

Is Ashdown Business Park, near Horney Common, within your area?

Yes. We cover Horney Common and the area around it, including industrial estates, business parks and retail parks such as Ashdown Business Park. A few photographs and the unit address let us price the work.

Is Horney Common too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

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, and we build that into the programme.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Surface by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, as the specification sets out.

Facade sealing around Horney Common: points for this area

The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. At about 34 miles from central London, Horney Common is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

New units and refits on sites such as Ashdown Business Park (1.5 miles south of Horney Common) need their panel and perimeter joints sealed to the specification. Work at a hotel such as Chequers Hotel (1.2 miles south of Horney Common) tends to be programmed around bookings, mastic included.

Why it’s worth doing now in Horney Common

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Halls, stores and units around places like Horney Common may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Horney Common can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Tell us what induction or permit system the site runs
