Facade sealing across Cross in Hand

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

General trades versus a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Facade sealing in Cross in Hand

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve perimeter sealant that has split or peeled away and weathered joints at frame-to-structure perimeters, across coping and flashing joints, perimeter joints where frames meet the structure and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Cross in Hand, preparation and product choice get the time they need.

For a site near Cross in Hand, 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 we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Specialist products, such as fire-rated or hygienic sealants
  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Any access equipment needed

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • The asbestos register, for older buildings
  • Any specification or named product
  • Whether the building will be occupied during the work
  • Any dates the work must fit around

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email drawings and photos.

Building and refurbishing in Cross in Hand

Cross in Hand is about 39 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Cross in Hand included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

When a school such as Cross-in-Hand Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For contractors refurbishing units at places like Station Road Industrial Estate, 1.5 miles east of Cross in Hand, the mastic covers cladding panels, roller-door and window perimeters.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites around Cross in Hand. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Different surfaces, different methods

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch without tearing.

Common problems we fix in Cross in Hand

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

If one of these sounds familiar, it’s time for a closer look:

  • Failed sealant on precast panel joints
  • Old perimeter mastic that has dried out
  • Staining on stone next to old sealant
  • Damp patches beside frames after rain

Extensions at sites like Uckfield Community Hospital (to the west of Cross in Hand) typically sit beside working departments, and the mastic follows strict access rules.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Will failed sealant be removed rather than covered?
  • How joint depth will be controlled
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Your questions answered

Can you work at a site such as Station Road Industrial Estate, by Cross in Hand?

Yes. Our area takes in Cross in Hand and its surroundings, with estates and business parks such as Station Road Industrial Estate included. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Would you work within a site like Uckfield Community Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards.

Does the weather affect the work?

For external joints, 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.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

How long before the joints can be used?

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

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Smaller jobs around Cross in Hand can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.
