Facade sealing near Na Gearrannan

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

What sets the cost

What shapes the price:

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Location, for remote and island sites
  • Phasing around occupants

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The asbestos register, for older buildings
  • Clear photos of the problem areas
  • The site address and postcode
  • Whether the building will be occupied during the work

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Facade sealing in Na Gearrannan, done properly

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We plan for that and keep you updated. Most enquiries involve perimeter sealant that has split or peeled away and gaps between rainscreen or cladding panels, across cladding panel joints, window and door perimeters and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Na Gearrannan is the same: the right product in a properly prepared joint.

Sites near smaller places like Na Gearrannan can mean longer travel, so the mastic is planned with as few trips as the job allows. Send drawings, photographs and the programme so everything needed arrives on the first day.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we’ll come back to it.

Surface by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Check that rainwater leaves the facade the way it was designed to
  • Inspect facade joints on a regular cycle
  • Check the asbestos register before old mastic is disturbed
  • Record the product and colour used on each elevation

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Tell us who will meet us and how to get in at your building near Na Gearrannan. That goes into the plan alongside the quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Before we start on site

  • Tell staff and tenants when we will be in
  • Send any specification or drawings in advance
  • Arrange parking or a loading space

Commercial clients in Na Gearrannan

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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

Questions about Na Gearrannan

Can the mastic package for our job in Na Gearrannan follow the site programme?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Does the sea air around Na Gearrannan change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

What do you charge?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Building and refurbishing in Na Gearrannan

Na Gearrannan is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Na Gearrannan is in the west of Scotland, the wetter side of the country. External mastic needs dry spells, with internal work ready to fill the wet days.

For contractors building in or near Na Gearrannan, we seal to the drawings, the specification and the programme. A facade joint near Na Gearrannan lasts when width, depth and backing are right, not just the finish.
