Facade sealing for businesses in Roundbush Green

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Plan facade sealing alongside redecoration
  • Ask about asbestos in pre-2000 mastic
  • Never let anyone seal over old sealant
  • Walk the elevations once or twice a year

Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.

Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

How we handle facade sealing in Roundbush Green

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints, and the usual reasons a site gets in touch are patch repairs that keep failing and weathered facade joints that have lost their grip. Most enquiries from Roundbush Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Conversions of older rural buildings near smaller places such as Roundbush Green bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Roundbush Green: questions and answers

Can you work to our programme on a site in or near Roundbush Green?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Roundbush Green outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

How much does the work cost?

We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How a job runs

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Smaller jobs around Roundbush Green can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work 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.
  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.

Preparing the site

  • Share the asbestos register for older buildings
  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Some joints are best left to specialists: 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.

Work for main contractors and building owners

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Roundbush Green can sit alongside others in a wider programme.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Sites and facades in and around Roundbush Green

The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. At about 28 miles from central London, Roundbush Green is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

For contractors at a school such as Rodings Primary School, sealing has to be finished before term starts. New units and refits on sites such as Parklands Business Centre, 1.1 miles to the south of Roundbush Green, need their panel and perimeter joints sealed to the specification.

What we’re called out for in Roundbush Green

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

Typical triggers for a call:

  • Old perimeter mastic that has dried out
  • Cold air coming in at window perimeters
  • Leaks at window and door perimeters
  • Gaps between rainscreen or cladding panels

Older buildings in the area around Roundbush Green, such as Barrington Hall, which lies north-west of Roundbush Green, need care when sealed: the product has to suit soft or historic materials.

What to look for in a quote

  • Whether their applicators hold CSCS cards
  • What the guarantee covers, and for how long
  • The named product and why it was chosen
  • How the existing material will be dealt with

Questions to ask before you appoint anyone

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure. Converted and older buildings near places like Roundbush Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
