Mastic sealing in Direcleit

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. We work on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks, and what we are called in for most is water getting in round frames after rain and movement joints with sealant missing. Facilities teams, main contractors and managing agents in Direcleit tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around Direcleit, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

General trades versus a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint typically 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.

For owners and agents in Direcleit

Direcleit sits close to the coast, within about 1 mile. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, so it’s worth inspecting those sides more often. Direcleit is on Scotland’s wetter western side. The weather side of a block typically needs attention first. We plan block programmes with the forecast in mind.

Trustees of buildings like Parish Church can bring frame and external mastic into a planned maintenance list. Owners near Direcleit can renew frame and external mastic block by block on one programme.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs near Direcleit are often grouped with others in the same area. Let us know if your dates have any give.

  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. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions

When it isn’t the sealant

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

  • Leaks through the frame itself rather than the perimeter
  • Materials that need asbestos testing before work
  • Glazing that needs replacing

Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.

Surfaces we seal

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

Questions about Direcleit

Can you take on a job in Direcleit, on the island?

Yes. Islands are part of our area, Direcleit included. We group island work where we can and plan around the crossings.

Does a coastal location like Direcleit affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

How much does the work cost?

We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

How do we ask for a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Why act early in Direcleit

Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Why us?

  • Fully insured, including public liability cover
  • Workmanship guaranteed for 12 months
  • Clear, fixed quotes
  • Joints cleaned back to sound surfaces

Read our cost guide or how we’re accredited.

What sets the cost

These are the things that shape the price:

  • Quantities, in metres or numbers
  • Working within restricted access windows
  • Any access equipment needed
  • Joint width, depth and condition

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Before you send an enquiry

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

  • A wide shot and a close-up of the area
  • Any specification or named product
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used
