How we handle mastic sealing in Lochmaddy
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks, and what we’re called in for most is brittle perimeter mastic across a building and damp patches beside frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lochmaddy, that means joint design, primers and backing rod as standard.
Around smaller places such as Lochmaddy, buildings managed by landlords and associations are often small groups of flats, sheltered housing and halls. Frames on exposed elevations are where mastic normally fails first.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Building owners, agents and FMs in Lochmaddy
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lochmaddy can sit alongside others in a wider programme across Na h-Eileanan Siar.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Leaks from above rather than through a joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think before you book.
Joints and surfaces we work on

Common questions from Lochmaddy clients
Do you work on the island where Lochmaddy is?
Yes. Islands are part of our area, Lochmaddy included. We plan island jobs around the ferry and the forecast, and bring everything the job needs on the first crossing.
Does a coastal location like Lochmaddy affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
What do you charge?
Each job is quoted on its own details. For yours, phone 01277 525 020 or email drawings and photos.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work for managing agents and housing associations?
Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
How many days will you need on site?
It depends on the scope, but the work normally takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Cost factors for mastic joints
There’s no standard rate for sealant work, because every site is different. What we look at:
- How much there is to seal
- The product specified
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
- The type of building and who uses it
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.
When to call us in Lochmaddy
The edges of the material itself sometimes break away for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Typical triggers for a call:
- The same joint failures repeated across a portfolio
- A mix of products and colours from past repairs
- Occupiers reporting cold air round windows
- Movement joints with sealant missing
Around Lochmaddy, a planned programme renews failed mastic across a building or estate in one go.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Health and safety accreditation such as CHAS
- Will RAMS and insurance details be available?
- Will CSCS-carded applicators be on site?
Blocks and managed buildings in Lochmaddy
With the shore within about 1 mile, Lochmaddy counts as a coastal location. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. The west of Scotland, where Lochmaddy is, gets more rain than the east. The weather side of a block typically needs attention first. Programmes allow for wet days.
Wherever your building is in or near Lochmaddy, we look at the whole elevation before quoting, so you know what needs doing now.
