Construction mastic in Irons Bottom

On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. If you have early adhesion failures on new external joints and snag items on joints that need redoing before handover, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Irons Bottom, preparation and product choice get the time they need.

Around smaller places like Irons Bottom, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Irons Bottom

When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference. Where an alternative is genuinely suitable, we will say so. One visit to deal with every failing joint makes more sense than several trips to a place like Irons Bottom, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • Workmanship guaranteed for 12 months
  • Colour agreed before work starts
  • Specification-led, product-correct work
  • Constructionline member for supplier checks

Signs you need construction mastic in Irons Bottom

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.

Clients typically get in touch after noticing one or more of the following:

  • External joints sealed in damp or cold conditions that are now failing
  • Failed sealant in an existing building being refurbished
  • Frame perimeters left unsealed or poorly sealed
  • Sanitary sealant damaged by following trades

When units on a site such as Fontigarry Farm Business Park, 0.7 miles south-east of Irons Bottom, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • Which product they’ll use, and why it suits the joint

Questions to ask before you appoint anyone

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • Damage to finishes by other trades after we have sealed
  • Frames fitted out of tolerance
  • Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

If in doubt, give us a call on 01277 525 020 or use the quote form and we’ll say what we think.

Quoting for work in Irons Bottom

Before we quote, we look at:

  • The size and state of each joint
  • Access and working height
  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Send us:

  • Any dates the work must fit around
  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us to discuss it first.

Your questions answered

Does your area include sites such as Fontigarry Farm Business Park, near Irons Bottom?

Yes. Estates, retail parks and business parks around Irons Bottom, Fontigarry Farm Business Park among them, are all within reach. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.

Can you work on a hospital site such as East Surrey Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you cover Irons Bottom?

Yes. We cover Irons Bottom. To discuss a job, phone 01277 525 020 or send details through our quote form.

Can you clear a mastic snag list before handover?

Yes. Snag-only work is something we take on.

Do you need to see the site first?

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.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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 where general trades tend to cut corners.

Diagnose, treat, 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. Jobs in and around smaller places like Irons Bottom are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Paperwork is agreed and applicators are inducted on site.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by our 12-month guarantee.

What we need from you

  • Warn occupants and staff about the work
  • Have the specification and drawings to hand
  • Flag any permit to work we will need

Request a quote

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
