Mastic sealing for commercial buildings in Basted

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in Basted carry our 12-month guarantee. We work on communal entrances and stairwells, balcony and threshold joints and shopfronts below residential blocks, and what we are called in for most is worn sealant at communal door frames and leaks at window and door perimeters. A single leaking joint is often how a building in Basted first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

For buildings around smaller places like Basted, we group work so one trip covers it. Send photos of the frames and joints and we will give a fixed quote.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Check sealant joints during planned building inspections
  • Keep bins and bikes away from communal door frames
  • List the paperwork your organisation requires when you send details
  • Encourage occupiers to report problems at frames

Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. Jobs in and around smaller places like Basted are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

What affects the price in Basted

Each job is priced on its own details. The main factors are:

  • Joint width, depth and condition
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • Phasing around occupants

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Specification clauses that apply
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • Whether an asbestos survey exists

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or use the quote form.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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

FAQs: Basted

Will you take on a block within reach of Borough Green & Wrotham station?

Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.

Is a smaller place like Basted outside your area?

Not at all: smaller places are covered as well as 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.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so it can be arranged.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Planned mastic for Basted portfolios

Basted is about 23 miles from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Basted included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.

Older community buildings, The Church of the Good Shepherd among them, often have frames of mixed ages whose mastic varies. Schools and community buildings such as Borough Green Primary School need frame and external mastic kept sound like any building. For owners of several units at places like Bourne Enterprise Centre, which lies north of Basted, one programme can deal with frame and external mastic across the lot.

Basted is about 5 miles east of Sevenoaks, in Kent. Businesses, contractors and managing agents in Basted can call on us for mastic joints, as part of our coverage of Kent. We work across 931 places in Kent. For work in that direction, see our London page (23 miles or so).

Why act early in Basted

A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Full removal and proper preparation is what lasts. One visit to deal with every failing joint makes more sense than several trips to a place like Basted. Photos of every joint help us quote for the whole job.

A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Different surfaces, different methods

External movement joints

Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.
