Mastic sealing in Crosshill

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. Most enquiries involve mastic failing across several blocks on an estate and damp patches beside frames, across shopfronts below residential blocks, window and door perimeters on blocks and balcony and threshold joints. A specialist sealant contractor works differently from a general builder: in Crosshill, that means joint design, primers and backing rod as standard.

Travel to smaller places like Crosshill is planned so several buildings can be done on one trip. A list of addresses and photos lets us quote for them together.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What happens if it’s left?

Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Crosshill, a repair visit takes planning, so it’s better to act early.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • Public liability insurance in place

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Substrate edges that need repairing first
  • Broken glass or failed sealed units
  • Frames that are rotten, warped or broken

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

Surfaces we seal

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

Your questions answered

We manage a building near Maybole station. Can you help?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Is Crosshill off your patch?

No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

How long does a job like this take?

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.

Can people stay in the building while you reseal?

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 reseal a whole block or estate?

Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Crosshill is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. We inspect the joints, building by building, and record what has failed and why.
  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

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Advice

Planned mastic for Crosshill portfolios

Crosshill is in the west of Scotland, the wetter side of the country. The weather side of a block typically needs attention first. We plan block programmes with the forecast in mind.

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Log resealing dates block by block
  • Share the asbestos register when you send details
  • List the paperwork your organisation requires when you send details
  • Make mastic part of routine maintenance checks

If paintable sealant was used, decoration can follow once it has cured. Silicone normally can’t be painted, so keep decorators off it.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Signs you need mastic sealing in Crosshill

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.

Common reasons buildings call us in:

  • Brittle perimeter mastic across a building
  • Mastic failing across several blocks on an estate
  • Water getting in round frames after rain
  • Movement joints with sealant missing

For agents with blocks near Maybole station, which lies north-west of Crosshill, a block-wide mastic programme deals with frames, balconies and entrances in one go.
