How we handle construction mastic in Hunton

Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, whatever the size of the scheme. If you have different trades sealing to different standards and mastic snags holding up handover, we can help. For commercial sealant work in Hunton, you deal with one contact from quote to sign-off, whether it’s one building or several.

Conversions of older rural buildings near smaller places such as Hunton 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What happens if it’s left?

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 and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Halls, stores and units around places like Hunton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why clients in Hunton choose us

  • A range of standard colours, depending on the product
  • One number for every site we cover
  • Fully insured, including public liability cover
  • RAL and finish matching where the product range allows

Questions about Hunton

Does your area include sites such as Woodfalls Industrial Estate, near Hunton?

Yes. Estates, retail parks and business parks around Hunton, Woodfalls Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Would you work within a site like Oakwood Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

What hours do you work?

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

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Can you clear a mastic snag list before handover?

Yes. We can work through a mastic snag list area by area before handover and damaged joints are redone properly.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Construction mastic around Hunton: what changes locally

At about 31 miles from central London, Hunton is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

When a school such as Hunton Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. University estates such as University for the Creative Arts - Maidstone (to the north-east of Hunton) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Extensions at sites like Oakwood Hospital, 3.7 miles to the north of Hunton, typically sit beside working departments, and the mastic follows strict access rules.

Hunton is about 4 miles south-west of Maidstone, in Kent. Commercial clients in Hunton use us for work on mastic packages, as part of our coverage of Kent. Our Kent coverage takes in 931 places, from busy centres to rural villages. Our London page has more on work in that area.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Hunton, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First we take quantities off the drawings and read through the specification.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. We close out snagging and hand over with a 12-month guarantee.

Preparing the site

  • Point out parking and an unloading spot
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

After the work

Keep the joints in good shape with a few simple steps:

  • Plan external elevations with the weather in mind
  • Use the product the specification names
  • Brief following trades on areas that have been sealed
  • Ask installers to correct oversized gaps first

Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby.

Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.

What the job involves on each surface

Snagging before handover

The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
