Mastic sealing near Annathill

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • List the paperwork your organisation requires when you send details
  • Encourage occupiers to report problems at frames
  • Include mastic in your cyclical inspections
  • Plan resealing building by building rather than complaint by complaint

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.

Mastic sealing for commercial buildings in Annathill

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on external wall and movement joints, window and door perimeters on blocks and balcony and threshold joints, and the failures we’re asked to look at most are leaks at window and door perimeters and movement joints with sealant missing. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Annathill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In smaller Scottish places like Annathill, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic usually fails first.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions about Annathill

Can you work at a site such as Westfield Industrial Estate, by Annathill?

Yes. Estates, retail parks and business parks around Annathill, Westfield Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Will you take on a block within reach of Gartcosh station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long do sealant joints last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Where we can, we combine work around Annathill with other jobs nearby. Let us know if your dates have any give.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs

Advice

Signs you need mastic sealing in Annathill

Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.

Most enquiries start with one or more of the following:

  • Repeated reactive repairs to the same buildings
  • Worn sealant at communal door frames
  • Failed external movement joints
  • Cracked, hardened mastic round windows on a block

For a school such as Greenfaulds High School, perimeter mastic on windows and doors is a holiday job.

Comparing quotes

  • Will CSCS-carded applicators be on site?
  • The terms of the workmanship guarantee
  • Proof of insurance
  • Will failed sealant be removed rather than covered?

Why it’s worth doing now in Annathill

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. For buildings near Annathill, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Why appoint us

  • One phone line for London, the South East and Scotland
  • A range of standard colours, depending on the product
  • Joints cleaned back to sound surfaces
  • Matching to RAL references, product permitting

Different surfaces, different methods

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

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.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Broken glass or failed sealed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

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

Joints and surfaces we work on

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