- A mix of products and colours from past repairs
- Failed external movement joints

- Cracked, hardened mastic round windows on a block

How we handle mastic sealing in Boquhan
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, communal entrances and stairwells and shopfronts below residential blocks, and the usual reasons a site gets in touch are brittle perimeter mastic across a building and complaints coming in block by block. For commercial sealant work in Boquhan, you deal with one contact from quote to sign-off, whether it’s one building or several.
For buildings around Boquhan, we group the work to keep travel and visits down. A list of addresses and photos lets us quote for them together.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What else we do in Boquhan
For owners and agents in Boquhan
Being in the west of Scotland, Boquhan gets more rain than eastern areas. The most exposed elevations need checking most often. External work is booked for dry spells, with a little give in the dates.

Questions about Boquhan
What documents will you need to give us for a job in Boquhan?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can one quote cover a number of our buildings near Boquhan?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Which sealant will you use?
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 weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is Boquhan in your area?
Yes. We cover Boquhan and the rest of Stirling. For a quote, speak to us on 01277 525 020 or email us.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Should maintenance staff do it?
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 easy to get wrong without experience.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Travel to smaller Scottish places like Boquhan is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints

How the job changes by surface
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. Colours are confirmed for the product used.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Broken glass or failed sealed units
- Leaks through the frame itself rather than the perimeter
- Substrate edges that need repairing first
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
