How we handle commercial sealant contractors in Hassell Street

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. If a material is suspected, work stops until it’s tested. Most enquiries involve movement joints packed with grit and debris and frame sealant that has cracked, shrunk or pulled away, across external facade joints, kitchen worktops and splashbacks and washrooms and tea points. Most enquiries from Hassell Street 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.

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

A job in a smaller place like Hassell Street is usually a single building. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we’re called out for in Hassell Street

A split down the middle of the bead tells a different story. That normally means the joint stretched further than the product could cope with: a bead laid too thin, an over-stretched joint or the wrong movement class. Replacing it like for like rarely holds.

Things that normally lead to an enquiry:

  • Shrunken sealant along kitchen worktops and splashbacks
  • Untidy joints in a reception, shop floor or lobby
  • Layers of sealant, all of them failing
  • Mouldy silicone around WCs, urinals and vanity tops

For premises near Wye station (2.7 miles west of Hassell Street), footfall is part of the plan: work is phased so shops and offices keep trading.

Choosing a commercial sealant contractor

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Hassell Street can form part of a wider programme.

Frontages, fit-outs and joints in Hassell Street

The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Hassell Street is about 52 miles from central London. This part of the South East is dense with business parks and out-of-town offices. Firms with branches across the South East can use one contractor for every site.

Whatever the building in Hassell Street, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Hassell Street can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Make sure the joints can be reached
  • Confirm the product named in the specification
  • Warn occupants and staff about the work

Your questions answered

Is a smaller place like Hassell Street outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Which documents can you supply for work in Hassell Street?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Make sure ventilation in wet areas is switched on and working
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Look at the sealant around anything that has been moved or replaced
  • Make sure contractors see the asbestos survey before cutting out old mastic

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records, and tell us if a joint we sealed gives trouble within that time.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

Why act early in Hassell Street

Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below. Resealing while only the sealant has failed keeps the job small. Halls, stores and units around places like Hassell Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
