Building and refurbishing in Fyfield

Fyfield is about 23 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Fyfield is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

For contractors at a school such as The Ongar Academy, sealing has to be finished before term starts. Sites around Fyfield get mastic sealed to the drawings and the programme, nothing improvised.

Fyfield is about 7 miles east of Harlow, in Essex. Our applicators travel to Fyfield for work on mastic packages. Our Essex coverage takes in 644 places, large and small. London is covered too, around 23 miles from Fyfield.

About our construction mastic in Fyfield

Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers on schemes in Fyfield, following the trades through the building as rooms and elevations become ready. Site teams most often ask us about old sealant on a refurbishment that needs stripping before new work and missed perimeter joints on a new elevation, on sanitary and kitchen joints, cladding and panel joints and internal decorators’ caulk. Whoever orders the work in Fyfield, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Fyfield 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 normally what’s needed.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Release areas for mastic once other trades have finished in them
  • Brief the final clean team to avoid blades near sealant
  • Plan external elevations with the weather in mind
  • Brief following trades on areas that have been sealed

After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.

Leave it or put it right?

A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Older rural buildings around Fyfield move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

We don’t publish prices, since every building and every scope is different. Call for a quote.

Why us?

  • Sealing commercial buildings since 2005

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Fyfield, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We walk the site or review drawings to understand the package.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  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. Final snagging is completed and the 12-month guarantee applies.

What we need from you

  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
  • Let building users know which areas are affected

Request a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Glazing units that are cracked or misted
  • Damage to finishes by other trades after we have sealed
  • Approving fire stopping as compliant

If you’re not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Fyfield: questions and answers

Is Fyfield too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What site paperwork comes with a job in Fyfield?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

What does a mastic package normally include?

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

Can you work plot by plot or floor by floor?

We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team and updated as the programme moves.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you work to our specification?

The specification decides the product, and we will raise it if something in it doesn’t suit the joint. Product standards such as BS EN 15651 are often named in specifications.
