Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Failed window or door frames, which need a window contractor
- Materials that need asbestos testing before work
- Leaks from above rather than through a joint

How we handle mastic sealing in Arnprior
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. The enquiries we see most involve complaints coming in block by block and cracked, hardened mastic round windows on a block, across balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Arnprior, preparation and product choice get the time they need.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Arnprior is planned with the forecast. Programmes allow for the weather.
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 else we do in Arnprior
For managing agents and facilities managers
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, with each stage agreed with your site contact.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Arnprior can sit alongside others in a wider programme.
Arnprior: questions and answers
Will you price a mastic programme across our Arnprior portfolio?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Which documents can you supply for work in Arnprior?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Different surfaces, different methods
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Common problems we fix in Arnprior
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
Things that usually lead to an enquiry:
- Draughts at frames across a block
- Worn sealant at communal door frames
- Mastic failing across several blocks on an estate
- Water getting in round frames after rain
For a building around Arnprior, a look at every elevation first shows which joints need renewing now and which can wait.
What to look for in a quote
- How they handle RAMS and site documents
- Their approach to joint depth and backing
- Will CSCS-carded applicators be on site?
- Whether old or failed sealant will be cut out, not overlaid
When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
