Commercial sealant contractors across Chartway Street

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the job changes by surface

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement; if the arrises are broken, we will say so before sealing.

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photos or a site visit tell us what’s needed, with colours confirmed for the product chosen.

Commercial sealant contractors in Chartway Street, done properly

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested. Site teams most often ask us about layers of sealant, all of them failing and untidy joints in a reception, shop floor or lobby, across washrooms and tea points, movement joints in walls and floors and floor and threshold joints. Whoever orders the work in Chartway Street, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In an occupied building in Chartway Street, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

In and around smaller places such as Chartway Street, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Looking after the joints

A few simple habits keep the new joints working:

  • Check sealant as part of routine building inspections
  • Log reseals in the O&M or maintenance records
  • Keep abrasive pads and scrapers off resealed joints
  • Report cracked or peeling sealant early

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.

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.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Suspect materials that need testing and specialist removal
  • A dripping trap, valve or pipe behind a fitting

If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

Questions about Chartway Street

Is Chartway Street off your patch?

Not at all. Chartway Street is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you match sealant colours for premises in Chartway Street?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

What about asbestos in old mastic?

It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you take on work for an FM or managing agent?

Yes. We quote, schedule and report back in the way that suits your process.

Will the building have to shut during the work?

It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Tell us what has to stay open and we will plan the job around it.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

General trades versus 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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

From enquiry to sign-off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Chartway Street need work, visits can be combined. You will have a fixed quote before work starts.

  1. First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements
