Leave it or put it right?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. A careful reseal is a far smaller undertaking than replacement, though we’ll tell you honestly if the element itself is the problem. For buildings around smaller places like Cock Clarks, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Common problems we fix in Cock Clarks

If sealant tears through its centre, it has failed cohesively. That normally means the joint stretched further than the product could cope with. The same product in the same joint tends to fail the same way, which is why we look at the joint design as well.

Common reasons buildings call us in:

  • Messy, uneven beads from earlier work that let the building down
  • Damp patches where an external joint has failed
  • Mouldy silicone around WCs, urinals and vanity tops
  • Shrunken sealant along kitchen worktops and splashbacks

For premises near South Woodham Ferrers station, 3.2 miles to the south of Cock Clarks, footfall is part of the plan: work is phased so shops and offices keep trading.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • How joint depth will be controlled
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Act on the first lifting edges rather than waiting
  • Don’t let cleaning or traffic back on before the cure time is up
  • Keep abrasive pads and scrapers off resealed joints

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records.

Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Cock Clarks may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

What we need from you

  • Send your site hours and access windows
  • Explain the parking and delivery arrangements
  • Agree which areas must stay open

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A dripping trap, valve or pipe behind a fitting
  • Structural cracks or movement the joints weren’t designed for
  • Faulty windows rather than failed perimeter sealant

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we’ll tell you honestly.

Surfaces we seal

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

Working on commercial sites near Cock Clarks

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. Cock Clarks is about 34 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

On a business park such as Wycke Hill Business Park (2.4 miles north-east of Cock Clarks), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Sites a few miles apart, such as Wycke Hill Business Park and Great Hayes Business Centre, can share one programme and one point of contact.

Cock Clarks is about 3 miles south-west of Maldon, in Essex. Cock Clarks sits inside our coverage and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else.

Cost factors for sealant joints

Before we quote, we look at:

  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • Specification clauses that apply
  • Photos of the joints, close up and from further back

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or send details through our quote form.

Your questions answered

Can you match sealant colours for premises in Cock Clarks?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photos and we will confirm what’s available for the product.

Is Cock Clarks too far out for you?

Not at all. Cock Clarks is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is it fine to apply new sealant on top of old?

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

How is commercial sealant work priced?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
