How we handle facade sealing in Irons Bottom

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and what we’re called in for most is previous reseals run over old sealant and old perimeter mastic that has dried out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Irons Bottom, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Irons Bottom bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we’ll come back to it.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Irons Bottom need work, visits can be combined, 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. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Share your working hours and any access restrictions
  • Tell staff and tenants when we’ll be in
  • Point out any areas we must not close

Advice

Building and refurbishing in Irons Bottom

At about 21 miles from central London, Irons Bottom is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Irons Bottom is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

For contractors at a college like Reigate College (2.5 miles north of Irons Bottom), perimeters and internal sealant are timed for the holidays. Units on estates such as Fontigarry Farm Business Park, 0.7 miles south-east of Irons Bottom, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Irons Bottom is about 2 miles south of Reigate, in Surrey. Any commercial site in Irons Bottom is covered. Irons Bottom is one of 379 places we cover in Surrey for facade joints. Sites around London have their own page, about 21 miles away.

Common questions from Irons Bottom clients

Is Irons Bottom too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Can work at a site such as Reigate College fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Will rain stop the work?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated throughout the job.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How is access to upper-level joints handled?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Building owners, agents and FMs in Irons Bottom

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Irons Bottom can form part of a wider programme across Surrey.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Different surfaces, different methods

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Specialist high-level access methods
  • Replacing glass or failed glazing units
  • Render or concrete edges that have broken away

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.

Where we work in Irons Bottom

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

Why deal with it now?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. For buildings around smaller places like Irons Bottom, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What you get with us

  • Colour options checked against the specified product
  • Coloured sealants to suit the setting, where available
  • Sealing commercial buildings since 2005
  • Failed material removed, not covered up

Signs you need facade sealing in Irons Bottom

The wrong product causes its share of trouble: 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.

Most enquiries start with one or more of the following:

  • Failed sealant on precast panel joints
  • Old perimeter mastic that has dried out
  • Unsightly perimeter sealant on a visible elevation
  • Perimeter joints where frames meet the structure

Projects at schools like Burys Court School work to term dates, so mastic is programmed tightly.

What your quote should include

  • Will RAMS and insurance details be available?
  • Can the work be phased to keep areas open?
  • Will CSCS-carded applicators be on site?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
