For owners and agents in South Stifford

The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. At about 17 miles from central London, South Stifford is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.

If you own or manage units on a site such as Lakeside Shopping Centre (0.6 miles west of South Stifford), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If your remit includes a building such as Harris Primary Academy Chafford Hundred, frame and door mastic can be programmed for the holidays. Student accommodation around universities such as University of Greenwich (3.2 miles south of South Stifford) is usually managed block by block, which suits a planned mastic programme.

From enquiry to 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 a job in South Stifford, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
  • Point out parking and an unloading spot

South Stifford: questions and answers

Can you quote for a block close to Chafford Hundred station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

Is South Stifford too far out for you?

Not at all. South Stifford is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you supply RAMS and insurance details?

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

How many days will you need on site?

It depends on the scope, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.

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.

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Redoing a failed joint usually costs more than getting it right at the outset, 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.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Group repairs into a planned programme
  • Have the asbestos survey to hand for older buildings
  • Log resealing dates block by block
  • Reduce knocks to communal area joints

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

Surface by surface

Tenement and older buildings

Natural stone can be marked by the wrong sealant and we choose accordingly.

Window and door perimeters on blocks

Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.

How the quote is worked out

These are the things that shape the price:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • How much there is to seal
  • Access and working height

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • How the joints are reached, and at what height
  • Clear photographs of the problem areas
  • Drawings or a marked-up plan, if available
  • What the building is and how it’s used

For a fixed quote, phone 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.
