Mastic sealing for businesses in Bessels Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For work around Bessels Green, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

What we need from you

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

What affects the price in Bessels Green

Your fixed quote is built from the real scope. It allows for:

  • Whether the work must be split into stages
  • The total length or number of joints
  • How accessible the joints are
  • How much existing material needs removing

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • The product your specification calls for
  • The site address and postcode
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Your questions answered

Is a smaller place like Bessels Green outside your area?

No. Places such as Bessels Green are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Salters Heath Business Centre, near Bessels Green, within your area?

Yes, sites like Salters Heath Business Centre are within our area, along with the rest of Bessels Green. Photos and a short description are enough for a first look.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.

Do you guarantee the mastic work?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Do you work with property factors and landlords?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

How long will the new sealant last?

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

Planned mastic for Bessels Green portfolios

Bessels Green lies roughly 19 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Bessels Green included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

Churches, halls and community buildings such as Chapel of the Good Shepherd are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. With historic buildings such as Knole House, 2.2 miles to the south-east of Bessels Green, in the wider area, owners of older properties around Bessels Green should expect mastic to need a product that suits old masonry. For owners of several units at places like Salters Heath Business Centre, under half a mile to the south of Bessels Green, one programme can deal with frame and external mastic across the lot.

Bessels Green is about 1 mile west of Sevenoaks, in Kent. We cover commercial sites throughout Bessels Green, whether it’s a single job or part of a planned programme. We work across 931 places in Kent. Our London page has more on work in that area.

Different surfaces, different methods

External movement joints

Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.

Window and door perimeters on blocks

On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.

Why it’s worth doing now in Bessels Green

Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. Halls, stores and units around places like Bessels Green 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.

What you get with us

  • CHAS accredited contractor
  • A range of standard colours, depending on the product
  • 12 months’ guarantee on every job
  • Fully insured, including public liability cover

What we can’t put right

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

  • Failed window or door frames, which need a window contractor
  • Glazing that needs replacing
  • Masonry that has broken away beside the joint

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

  • External wall and movement joints
  • Balcony and threshold joints
  • Communal entrances and stairwells
  • Shopfronts below residential blocks
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks

Should maintenance staff do it?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
