Advice

Construction mastic in High Hurstwood

Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list. We seal so the snag list stays short, whatever the size of the scheme. We work on internal decorators’ caulk, brick and block movement joints and floor and skirting junctions, and what we are called in for most is failed sealant in an existing building being refurbished and early adhesion failures on new external joints. Whoever orders the work in High Hurstwood, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as High Hurstwood is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

FAQs: High Hurstwood

Does your area include sites such as Ashdown Business Park, near High Hurstwood?

Yes, sites like Ashdown Business Park are within our area, along with the rest of High Hurstwood. Send details of the unit and the work through our quote form for a quick quote.

Can you take on a job at a hospital such as Crowborough War Memorial Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Can staff carry on working while you are here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

What joints do you seal on a new build?

Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.

Maintenance after handover

Once the work is signed off, these steps help:

  • Stick to the specified sealant rather than a generic substitute
  • Protect sealed areas from following trades
  • Keep product details for future maintenance
  • Check frame gaps are within the sealant’s range before sealing

After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.

External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Specifying the product where the designer hasn’t
  • Approving fire stopping as compliant
  • Damage to finishes by other trades after we have sealed

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

What we seal

  • Cladding and panel joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Window and door perimeters
  • Internal decorators’ caulk
  • Sanitary and kitchen joints

Do you need construction mastic in High Hurstwood?

Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.

It’s worth sending us details if you spot any of the following:

  • Early adhesion failures on new external joints
  • Missed perimeter joints on a new elevation
  • Failed sealant in an existing building being refurbished
  • Sanitary sealant damaged by following trades

When a school such as High Hurstwood Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Before you book anyone

  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Whether primer will be used where the manufacturer specifies it
  • Their public liability cover

Building and refurbishing in High Hurstwood

High Hurstwood is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. At about 35 miles from central London, High Hurstwood 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.

New units and refits on sites such as Ashdown Business Park, 2.8 miles south-west of High Hurstwood, need their panel and perimeter joints sealed to the specification. Hospital estates such as Crowborough War Memorial Hospital, 2.7 miles north-east of High Hurstwood, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

High Hurstwood is about 3 miles south-west of Crowborough, in East Sussex. Commercial clients in High Hurstwood can call on us for mastic packages. We work across 308 places in East Sussex. Sites around Brighton have their own page, roughly 17 miles from High Hurstwood.

What affects the price in High Hurstwood

The price varies from site to site. Expect it to depend on:

  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Quantities, in metres or numbers
  • How much existing material needs removing

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.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • Whether the building will be occupied during the work
  • The postcode of the building

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email us.
