Mastic sealing for commercial buildings in Baltasound
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. If you have draughts at frames across a block and brittle perimeter mastic across a building, we can help, whatever the surface. Looking for mastic applicators who cover Baltasound? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Around Baltasound, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Owners, agents and contractors
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
FAQs: Baltasound
Can you take on a job in Baltasound, on the island?
Yes. Our area covers all of Scotland, cities, towns and islands alike, and that includes island locations such as Baltasound. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Will you price a mastic programme across our Baltasound portfolio?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we’ll give a fixed quote.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
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. Internal work is far less affected.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal joints high up on a block?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
What sets the cost
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Which sealant the job calls for
- Joint width, depth and condition
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Whether the building will be occupied during the work
- Specification clauses that apply
- The site address and postcode
- Your programme or deadline
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints. For a building near Baltasound, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.

Communal areas
Low-level communal joints get damaged more than most, so they often need renewing sooner.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Other services in Baltasound
Common problems we fix in Baltasound
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and it tears.
Look out for the following:
- Window mastic that has split and shrunk
- Draughts at frames across a block
- A mix of products and colours from past repairs
- Failed external movement joints
Churches, halls and community buildings such as Kirkhoull are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Before you book anyone
- Health and safety accreditation such as CHAS
- Proof of insurance
- Can the work be phased to keep areas open?
- Do they follow the manufacturer’s priming guidance?
For owners and agents in Baltasound
Baltasound is within about 2 miles of the coast. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. Baltasound is on Scotland’s drier eastern side. Outside mastic still waits for dry, frost-clear conditions. Block programmes are built with that in mind
Site managers at schools like Baltasound Junior High School can fit frame mastic into the summer works.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
