Mastic sealing for Melvich sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Tell us who will meet us and how to get in at your building near Melvich. That goes into the plan alongside the quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000

Quotes

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

About our mastic sealing in Melvich

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, external wall and movement joints and window and door perimeters on blocks, and the failures we are asked to look at most are leaks at window and door perimeters and draughts at frames across a block. Whether you call it commercial sealant work, mastic application or joint sealing, in Melvich it comes down to the same thing: the right product in a properly prepared joint.

Outside mastic in Scotland needs dry joints and the right temperature, so work around Melvich is planned with the forecast. Programmes allow for the weather.

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.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Signs you need mastic sealing in Melvich

Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified it comes away from one face.

If one of these sounds familiar, it’s time for a closer look:

  • Patchy repairs in mismatched sealant
  • Occupiers reporting cold air round windows
  • Water getting in round frames after rain
  • Mastic failing across several blocks on an estate

Around Melvich, a planned programme renews failed mastic across a building or estate in one go.

  • Their public liability cover
  • Are they CHAS accredited or on Constructionline?
  • Whether their applicators hold CSCS cards
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Surface by surface

External movement joints

Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Check sealant joints during planned building inspections
  • Group repairs into a planned programme
  • Keep a record of when each building was resealed
  • Have the asbestos survey to hand for older buildings

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Left open, joint edges in render, brick or frames can deteriorate. Then the edges may need repairing first and the job grows.

Questions about Melvich

Can you quote for mastic across several buildings in and around Melvich?

Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.

Is a smaller place like Melvich outside your area?

No. Small places get the same service as large ones. We work across every Scottish council area. Where we can, we group nearby jobs to make the most of each trip.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

When can the area be used after sealing?

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

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

What about access for upper-floor joints?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
