About our facade sealing in Greensted Green

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We plan for that and keep you updated. The enquiries we see most involve weathered facade joints that have lost their grip and new sealant peeling off old mastic, on stone and brick facade joints, perimeter joints where frames meet the structure and cladding panel joints. Most enquiries from Greensted Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions of older rural buildings near smaller places such as Greensted Green bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Avoid harsh cleaners on facade sealant
  • Keep sills, gutters and drainage paths clear
  • Keep the sealant details on the building file
  • Ask about asbestos in pre-2000 mastic

Keep a note of which product went in and when. Future work can then match the product and colour.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Common questions from Greensted Green clients

Is hospital work, at somewhere like St. Margaret's Hospital, something you do?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Greensted Green too small for you to travel to?

No. Places such as Greensted Green are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Will you come and look before quoting?

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

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.

Do you replace windows or glass?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Sites and facades in and around Greensted Green

Rainfall across the South East, Greensted Green included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. At about 19 miles from central London, Greensted Green is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

For a contractor at a hotel such as Phoenix Epping Hotel (1.4 miles north-west of Greensted Green), the mastic often has to be finished before a reopening date. Historic houses such as Hill Hall (3.2 miles south-west of Greensted Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Greensted Green is about 6 miles south-east of Harlow, in Essex. Looking for facade sealing in Greensted Green? We can help, as we do across Essex. We work across 644 places in Essex, from busy centres to rural villages. We also cover London, some 19 miles away.

What the job involves on each surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

What we are called out for in Greensted Green

When the sealant tears down its centre, it has typically been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Common reasons buildings call us in:

  • Cladding panel joints that have opened up
  • Perimeter sealant that has split or peeled away
  • Draughts around frames and panels
  • Unsightly perimeter sealant on a visible elevation

New units and refits on sites such as North Weald Industrial Estate (2.2 miles west of Greensted Green) need their panel and perimeter joints sealed to the specification.

Choosing a commercial sealant contractor

What sets the cost

We price every job individually. The things that drive the figure:

  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits
  • Phasing around occupants

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • The site address and postcode
  • Your programme or deadline
  • The type of building and who uses it
  • How the joints are reached, and at what height

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Movement beyond what any sealant can handle
  • Cracked or spalling substrates that need repair before sealing
  • Replacing glass or failed glazing units

If you’re not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.

What we seal

  • Cladding panel joints
  • Shopfront frames
  • Window and door perimeters
  • Stone and brick facade joints
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Greensted Green, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready
