Common questions from Hawkenbury clients

Is Hawkenbury off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Barradale Farm Industrial Estate, near Hawkenbury?

Yes. Our area takes in Hawkenbury and its surroundings, with estates and business parks such as Barradale Farm Industrial Estate included. A few photos and the unit address let us price the work.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we will set out a timescale with the quote.

What guarantee do you give on resealing?

Our workmanship is guaranteed for 12 months. We’re fully insured for public liability as well.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

What do you need from us to quote?

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.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Commercial sealant contractors in Hawkenbury, done properly

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. We work on kitchen worktops and splashbacks, external facade joints and washrooms and tea points, and the usual reasons a site gets in touch are movement joints packed with grit and debris and weathered facade sealant that no longer flexes. A specialist sealant contractor works differently from a general builder: in Hawkenbury, that means joint design, primers and backing rod as standard.

If you look after more than one building near Hawkenbury, the work can be planned as one programme, so standards and paperwork match across every site.

Business units in the countryside around places like Hawkenbury are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Suspect materials that need testing and specialist removal
  • Roof leaks that only look like a joint problem
  • Leaks from pipework, wastes or valves (that’s plumbing)

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly.

Where we work in Hawkenbury

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

Surface by surface

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed, and we’ll confirm the colours available for the specified product.

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we’ll say so before sealing.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from part of a day on a short run of joints to several weeks on a large phased package, and our waste is bagged and taken away as we go. Smaller jobs around Hawkenbury can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Preparing the site

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Let us know about inductions and permits

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Why it’s worth doing now in Hawkenbury

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. Resealing usually costs far less than renewal, though we will tell you honestly if the element itself is the problem. Converted and older buildings near places like Hawkenbury tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Frontages, fit-outs and joints in Hawkenbury

Hawkenbury sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. At about 37 miles from central London, Hawkenbury is within reach of the capital. This part of the South East is dense with business parks and out-of-town offices. If you have premises across the region, one contractor can cover them all.

For premises near Staplehurst station, which lies west of Hawkenbury, footfall is part of the plan: work is phased so shops and offices keep trading. Industrial estates such as Barradale Farm Industrial Estate, 1.3 miles east of Hawkenbury, have offices, trade counters and welfare areas whose sealant ages like any other building’s.
