About our mastic sealing in Finkley Down

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you have movement joints with sealant missing and damp patches beside frames, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Finkley Down, preparation and product choice get the time they need.

In and around smaller places like Finkley Down, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Quoting for work in Finkley Down

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Induction, permit and paperwork requirements
  • The product specified
  • Joint width, depth and condition
  • Removal of failed or old sealant

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

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • When you need the work done
  • Access details, including height
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Keep a record of when each building was resealed
  • Look at the sunniest and most exposed elevations first
  • Check the asbestos register before any old mastic is disturbed
  • Keep bins and bikes away from communal door frames

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. For work around Finkley Down, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First we look at the mastic on each building and note what needs replacing.
  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. Each building is checked on completion and the work carries our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions

Your questions answered

Do you work for managing agents with blocks near Andover station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.

Is Finkley Down off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Will residents or tenants be disturbed?

Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.

Can you send RAMS and CSCS details before starting?

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

Can you plan resealing across several buildings?

Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

Can you take on resealing for a block portfolio?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.

If you look after a block within reach of Andover station (2.1 miles west of Finkley Down), frame and balcony mastic can be renewed on one programme. If your remit includes a building such as Vigo Primary School, frame and door mastic can be programmed for the holidays.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Glazing that needs replacing
  • Failed window or door frames, which need a window contractor

If in doubt, ring 01277 525 020 or email us 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
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks
  • Shopfronts below residential blocks

What we’re called out for in Finkley Down

The edges of the material itself sometimes break away for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.

Clients usually get in touch after noticing something like this:

  • Old repairs sealed over failed mastic
  • Complaints coming in block by block
  • Mastic failing across several blocks on an estate
  • Damp patches beside frames

Landlords with units on estates such as Walworth Business Park (to the south-west of Finkley Down) can bring frame, door and external mastic across several units into one programme.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
