Commercial sealant contractors near Brasted Chart

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Sealant specialists in Brasted Chart

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). The enquiries we see most involve wall and floor joints that have lost their seal and mouldy silicone around WCs, urinals and vanity tops, on window and door perimeters, movement joints in walls and floors and floor and threshold joints. A specialist sealant contractor works differently from a general builder: in Brasted Chart, that means joint design, primers and backing rod as standard.

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

A job in a smaller place like Brasted Chart is typically a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we will come back to it.

Commercial premises in Brasted Chart

Brasted Chart sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. A 2-mile radius around Brasted Chart takes in several hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet; work is planned so the hotel keeps trading.

A hotel such as The King's Arms Hotel (to the west of Brasted Chart) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Offices and shops close to stations such as Sevenoaks station, 3.6 miles east of Brasted Chart, tend to be busy all day, so sealant work is planned around opening hours.

Brasted Chart is about 4 miles west of Sevenoaks, in Kent. We send applicators to Brasted Chart for sealant joints, handled exactly as we handle every other area. We work across 931 places in Kent, from busy centres to rural villages. London is covered too, some 18 miles away.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Quantities, in metres or numbers
  • Access and working height
  • Travel to remote or island sites
  • The site’s rules and procedures

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • The asbestos register, for older buildings
  • When you need the work done
  • The type of building and who uses it
  • Anything awkward about access or site hours

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Common problems we fix in Brasted Chart

If sealant tears through its centre, it has failed cohesively. That normally means the joint stretched further than the product could cope with. Replacing it like for like rarely holds, so width, depth and product are checked before we quote.

Things that typically lead to an enquiry:

  • Mouldy silicone around WCs, urinals and vanity tops
  • Leaks that seem to come through a sealant line
  • Untidy joints in a reception, shop floor or lobby
  • Earlier reseals applied straight onto the failed bead

For tenants and agents on sites such as Salters Heath Business Centre, which lies east of Brasted Chart, office fit-outs, reception joints and window perimeters are the usual sealant work.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • How they handle RAMS and site documents
  • Will CSCS-carded applicators be on site?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Brasted Chart are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  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.

Getting the site ready

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Point out any areas we must not close

Related advice

What happens if it’s left?

Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Halls, stores and units around places like Brasted Chart may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Questions about Brasted Chart

Do hotels near Brasted Chart have to close for sealant work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. We agree the order of rooms and the timings with you before we start.

Is Brasted Chart too far out for you?

No. Places such as Brasted Chart are covered as much as the big towns. 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.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Are you CHAS accredited and on Constructionline?

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

Will the building have to shut during the work?

It’s normal for us to work in occupied buildings. We agree the order of areas, protect what’s nearby and close off only the section we are sealing, until its cure time has passed.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Which site documents can you send us?

The paperwork is agreed with the quote: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.

Maintenance after handover

Cleaning and maintenance staff play a part too. Share these points with them:

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Deal with small splits before they become leaks
  • On pre-2000 buildings, share the asbestos information before work starts
  • Log reseals in the O&M or maintenance records

New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Keeping signs or barriers up until then protects the finish.

Sealant installed at the same time typically fails in sequence. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
