Questions about St Marys
Does your area include sites such as Dryburgh Industrial Estate, near St Marys?
Yes, sites like Dryburgh Industrial Estate are within our area, along with the rest of St Marys. Send details of the unit and the work through our quote form for a quick quote.
How do tenement owners in St Marys get shared-part mastic done?
Normally the owners agree it together, and a property factor often handles the arrangements. We’re happy to deal with the factor directly.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can you seal external joints in wet or cold weather?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. External work is sequenced with some flexibility.
How much does the work cost?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email us with a description of the work.
About our construction mastic in St Marys
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. We work on internal decorators’ caulk, window and door perimeters and cladding and panel joints, and the failures we’re asked to look at most are caulk cracking where joints are moving more than expected and existing joints on a refurb that need cutting out and resealing. Most enquiries from St Marys start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in Scotland’s cities is a mix of new build and work to existing stone buildings. Work comes under Scotland’s own building standards, and our job is to seal to the specification.
Our workmanship is guaranteed for 12 months, in St Marys as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Contractors’ notes for St Marys
St Marys sits close to the coast, within about 3 miles. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Projects in St Marys follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification.
New units and refits on sites such as Dryburgh Industrial Estate, 0.6 miles south of St Marys, need their panel and perimeter joints sealed to the specification. When a school such as Lawside Academy is extended or refurbished, the mastic package is often squeezed into the holidays.
St Marys is about 2 miles north-west of Dundee, in Dundee. If you’re looking for construction mastic in St Marys, we can help. St Marys is one of 28 places we cover in Dundee.

How the quote is worked out
Each job is priced on its own details. The main factors are:
- Access and working height
- Which sealant the job calls for
- The total length or number of joints
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Anything awkward about access or site hours
- Any specification or named product
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Deciding which fire-stopping product a penetration needs
- Specifying the product where the designer hasn’t
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.
Joints and surfaces we work on
- Window and door perimeters
- Sanitary and kitchen joints
- Brick and block movement joints
- Cladding and panel joints
- Internal decorators’ caulk
- Floor and skirting junctions
Different surfaces, different methods
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Tell us what records you need and we will confirm with the quote.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere following the programme.
Common problems we fix in St Marys
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Choosing the right product for each joint reduces that.
Look out for the following:
- Early adhesion failures on new external joints
- Old sealant on a refurbishment that needs stripping before new work
- Inconsistent sealant finishes from plot to plot
- Mastic snags holding up handover
New wings at hospitals like Kings Cross Hospital (1.5 miles south-east of St Marys) bring long runs of window and panel joints to seal.
What to look for in a quote
- How joint depth will be controlled
- How long is the guarantee, and what does it include?
- What level of public liability insurance do they hold?
- Whether their applicators hold CSCS cards
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For premises in St Marys, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Flag any permit to work we’ll need
- Share the asbestos register for older buildings

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
