What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Suspect materials that need testing and specialist removal
  • Structural cracks or movement the joints weren’t designed for
  • A failed roof covering or waterproofing membrane

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

  • Washrooms and tea points
  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Window and door perimeters
  • Floor and threshold joints
  • External facade joints

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in Broad Street Green, the quickest start is to speak to us on 01277 525 020 or email us with a list of addresses. If you have water staining near frames, panels or ceilings and earlier reseals applied straight onto the failed bead, we can put it right, whatever the surface. Whoever orders the work in Broad Street Green, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

If you look after more than one building near Broad Street Green, the work can be planned as one programme, with one quote format and one point of contact.

Business units in the countryside around places like Broad Street Green are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Every job we finish is backed by a 12-month workmanship guarantee, in Broad Street Green as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Broad Street Green clients

Can you work at a site such as The Causeway Industrial Estate, by Broad Street Green?

Yes, sites like The Causeway Industrial Estate are within our area, along with the rest of Broad Street Green. Photos and a short description are enough for a first look.

Does the sea air around Broad Street Green change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is the old sealant taken out first?

Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts.

What about asbestos in old mastic?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

After the work

Regular inspection catches problems early. In particular:

  • Put external and wet-area joints on a regular inspection round
  • Report cracked or peeling sealant early
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Check the asbestos register before anyone disturbs old sealant in an older building

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Keeping signs or barriers up until then protects the finish.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Common problems we fix in Broad Street Green

A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. By the time it shows, there can be two or three layers to cut out.

If one of these sounds familiar, it’s time for a closer look:

  • Frame mastic that has hardened and come away from the wall
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Water staining near frames, panels or ceilings
  • Greasy, split joints in a kitchen or tea point

Occupiers with premises at both The Causeway Industrial Estate and Leigh Industrial Estate could have the sealant at each handled under one quote.

  • How they’ll work around occupants
  • Will CSCS-carded applicators be on site?

Our contractor checklist

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Sealant on show in Broad Street Green’s commercial buildings

Broad Street Green lies within about 3 miles of the sea. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. Sea-facing elevations are normally where failed joints show first. The South East is one of the drier parts of the UK. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up.

Premises within reach of Witham station (to the north-west of Broad Street Green) often have busy frontages where joints are seen by everyone passing. Trade counters and showrooms on estates such as The Causeway Industrial Estate (to the south-west of Broad Street Green) need neat joints where customers see them.

Broad Street Green is about 2 miles north of Maldon, in Essex. We send applicators to Broad Street Green for sealant joints, handled exactly as we handle every other area. Across Essex, 644 places are covered, including Broad Street Green. Sites around London have their own page, roughly 38 miles from Broad Street Green.

We cover the CM9 postcode districts for sealant joints. Nearby places we also cover include Heybridge (1 mile south), Great Totham (1 mile north), Langford (1 mile west), Wickham Bishops (2 miles north-west) and Beacon Hill (2 miles north) for sealant joints.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Broad Street Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First, details reach us through the quote form or a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Tell us which areas need to stay in use
  • Arrange parking or a loading space
  • Make sure the joints can be reached
