Construction mastic in High Easter

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Construction mastic in High Easter, done properly

We work to the specification and the programme. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance. Site teams most often ask us about early adhesion failures on new external joints and old sealant on a refurbishment that needs stripping before new work, on internal decorators’ caulk, floor and skirting junctions and window and door perimeters. For commercial sealant work in High Easter, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In the countryside around places like High Easter, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Honest limits

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

  • Approving fire stopping as compliant
  • Oversized gaps that need packing or adjustment by others
  • Defective windows, doors or glazing units (the supplier or installer’s job)

Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.

Where we work in High Easter

Facades, frames and programmes in High Easter

Rainfall across the South East, High Easter included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. High Easter lies roughly 29 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

New units and refits on sites such as Parklands Business Centre, 2.6 miles west of High Easter, need their panel and perimeter joints sealed to the specification. New wings at hospitals like Broomfield Hospital, 5.1 miles south-east of High Easter, bring long runs of window and panel joints to seal.

High Easter is about 7 miles north-west of Chelmsford, in Essex. Commercial clients in High Easter can call on us for mastic packages. We work across 644 places in Essex. There’s a separate page for London, about 29 miles away.

Questions we are asked in High Easter

Is High Easter too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Broomfield Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What do you charge?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. For a building around High Easter, tell us how to find it and who will meet us. Send that with the details and we will 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. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

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

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Working within restricted access windows
  • How much existing material needs removing
  • Joint width, depth and condition
  • The product specified

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • Clear photographs of the problem areas
  • The product your specification calls for

For a fixed quote, phone 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.

What the job involves on each surface

External facade and movement joints

External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it and work only when conditions suit.

Fire-rated sealant where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.

What happens if it’s left?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. Older rural buildings around High Easter move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
