Your questions answered
Can being near the sea in Holm affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Will you travel to Holm on the island?
Yes. Every Scottish council area is within our area, and that includes island locations such as Holm. Island work is planned around ferry crossings and the weather, so photos and a full list before we travel are essential.
How long does a job like this take?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
How do you handle work on occupied blocks?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
About our mastic sealing in Holm
Across Holm and the rest of Na h-Eileanan Siar, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. Most enquiries involve window mastic that has split and shrunk and draught complaints from residents or tenants, on communal kitchens and washrooms, communal entrances and stairwells and balcony and threshold joints. Facilities teams, main contractors and managing agents in Holm tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around Holm, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Masonry that has broken away beside the joint
- Leaks from above rather than through a joint
- Leaks through the frame itself rather than the perimeter
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
Where we work in Holm
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
Keeping the joints sound
A few simple habits keep the new joints working:
- Share your contractor requirements early
- Keep a record of when each building was resealed
- Group repairs into a planned programme
- Have the asbestos survey to hand for older buildings
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Quoting for work in Holm
These are the things that shape the price:
- Whether the work must be split into stages
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- Any access equipment needed
There’s no price list, since every building and every scope is different. Call for a quote.
What to include in your enquiry
However big the job, the same details help:
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send details through our quote form.
Looking after buildings in and around Holm
With the shore within about 1 mile, Holm counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Being in the west of Scotland, Holm gets more rain than eastern areas. Exposed elevations on blocks take a soaking and their mastic shows it. We plan block programmes with the forecast in mind.
For owners of several units at places like Parkend Industrial Estate, 0.5 miles to the north-west of Holm, one programme can deal with frame and external mastic across the lot. Owners near Holm can renew frame and external mastic block by block on one programme.
Holm is about 2 miles south-east of Stornoway, in Na h-Eileanan Siar. We cover Holm, with the same fixed quotes and 12-month guarantee as everywhere else. 87 places across Na h-Eileanan Siar fall within our area, Holm among them.
Work on mastic joints is covered throughout HS2, whatever the building. We cover commercial and managed buildings on Holm Road and Parkend and the roads nearby. Close to Holm, our area also takes in Sanndabhaig (1 mile north-west), Branahuie (1 mile north-east), Bràigh na h-Aoidhe (1 mile north-east), Sandwick (1 mile north-west) and Plasterfield (1 mile north-west). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so mention the location when you call the office on 01277 525 020 or email a schedule or drawings.
Near you in Holm
A little further out are Western Isles Hospital (2.5 miles north-west) and Lewis Loom Centre (2.3 miles north-west). The countryside around Holm includes Loch Àirigh na Lic.
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
On site: what to expect
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. For a building near Holm, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in
- Clear stock, furniture or equipment away from the joints

Why act early in Holm
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Holm, a repair visit takes planning, so it’s better to act early.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
