When to call us in Betsham

If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Clients usually get in touch after noticing one or more of the following:

  • Wall and floor joints that have lost their seal
  • Messy, uneven beads from earlier work that let the building down
  • Frame mastic that has hardened and come away from the wall
  • Greasy, split joints in a kitchen or tea point

Offices and shops close to stations such as Longfield station (to the south of Betsham) tend to be busy all day, so sealant work is planned around opening hours.

How to choose a sealant contractor

Commercial mastic work in Betsham

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). Site teams most often ask us about shrunken sealant along kitchen worktops and splashbacks and black mould through washroom sealant that won’t clean off, across kitchen worktops and splashbacks, external facade joints and movement joints in walls and floors. Most enquiries from Betsham 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.

On a typical commercial building in Betsham, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

Commercial sealant work around smaller places like Betsham tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes part of a day on a small job and longer where several buildings or phases are involved. Rural sites near Betsham may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  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. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
  • Share your working hours and any access restrictions

Advice

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Broken glass or blown double-glazed units
  • Structural cracks or movement the joints weren’t designed for
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer.

Surfaces we seal

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

Working on commercial sites near Betsham

At about 18 miles from central London, Betsham is within reach of the capital. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site. The 3 miles around Betsham take in at least three named trading estates, business parks or retail parks. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies.

Sites a few miles apart, such as Fawkham Business Park and Ebbsfleet Business Park, can share one programme and one point of contact. Offices at parks like Fawkham Business Park, 1.7 miles south of Betsham, have receptions, kitchens and glazed partitions where a tidy joint matters.

Betsham is about 2 miles south-west of Northfleet, in Kent. Businesses, contractors and managing agents in Betsham use us for work on sealant joints. Across Kent, 931 places are covered, Betsham among them. Our London page has more on work in that area.

Why deal with it now?

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. We can price both options so you can decide on the facts. One visit to deal with every failing joint makes more sense than several trips to a place like Betsham. Send photographs of each area and we’ll quote for the lot.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

After the work

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

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Don’t let cleaning or traffic back on before the cure time is up
  • Keep a record of which joints were resealed and when

We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

Betsham: questions and answers

Is Betsham too small for you to travel to?

Not at all. Betsham is within our area. We cover Greater London and the counties of 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 supply sealant in our brand colour for a site in Betsham?

Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photos and we’ll confirm what’s available for the product.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

What site paperwork can you provide?

We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.

Do you seal on top of existing sealant?

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

When can the area be used after sealing?

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.

How long do sealant joints last?

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 inspection is the best way to catch problems early.
