  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Advice

About our facade sealing in Greensted

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Most enquiries involve weathered facade joints that have lost their grip and previous reseals run over old sealant, across stone and brick facade joints, shopfront frames and perimeter joints where frames meet the structure. One point of contact handles commercial sealant work in Greensted from the first photographs to the final walk-round, whether it’s one building or several.

For a site near Greensted, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we’ll quote to suit.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Common questions from Greensted clients

Is a smaller place like Greensted outside your area?

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

Can you work at a site such as Hallsford Bridge Industrial Estate, by Greensted?

Yes, sites like Hallsford Bridge Industrial Estate are within our area, along with the rest of Greensted. Photos and a short description are enough for a first look.

What will the job cost?

We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Can you just add new sealant on top?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Which sealant do you use on facades?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Include photographs or drawings if you have them.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Do you need facade sealing in Greensted?

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

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

  • Hard, chalky sealant that no longer flexes
  • Failed seals around shopfront and entrance frames
  • Sealant pulling away from frames or panels
  • Discoloured or dirty facade joints

When a school such as Chipping Ongar Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Comparing quotes

  • How the joint faces will be prepared and primed
  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed
  • How much existing material needs removing
  • Phasing around occupants

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Looking after the joints

To get the most from the new sealant:

  • Don’t wait for a second leak before calling
  • Clear debris that holds water against joints
  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Installing or repairing glazing systems
  • Damaged frames that need replacing
  • Damp caused by condensation inside the building

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Facade sealing around Greensted: points for this area

At about 20 miles from central London, Greensted is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Greensted sits in one of the drier corners of the country, the South East. 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.

Historic houses such as Hill Hall, 3.8 miles south-west of Greensted, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. On a healthcare site such as St. Margaret's Hospital, which lies west of Greensted, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Greensted is about 5 miles east of Epping, in Essex. Any commercial site in Greensted is covered, whether it’s a single job or part of a planned programme. 644 places across Essex fall within our area, Greensted among them. London is covered too, some 20 miles away.
