Mastic sealing for Colliston sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Materials that need asbestos testing before work
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
What we seal
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Balcony and threshold joints
About our mastic sealing in Colliston
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you are dealing with worn sealant at communal door frames and occupiers reporting cold air round windows, we can put it right. Whoever orders the work in Colliston, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places such as Colliston, 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. The promise is simple: if our work fails within that year, we put it right.

Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Where we can, we combine work around Colliston with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Send any specification or drawings in advance
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs

Related advice
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Colliston can form part of a wider programme.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Frames, entrances and external joints in Colliston
Being in the east of Scotland, Colliston gets less rain than the west coast. Outside mastic still waits for dry, frost-clear conditions. Programmes allow for that

Questions we are asked in Colliston
Will you take on a block within reach of Arbroath station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Is Kirkton Industrial Estate, near Colliston, within your area?
Yes. Our area takes in Colliston and its surroundings, with estates and business parks such as Kirkton Industrial Estate included. Photos and a short description are enough for a first look.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.

How the quote is worked out
The price varies from site to site. It mainly depends on:
- The product specified
- Location, for remote and island sites
- Working within restricted access windows
- Quantities, in metres or numbers
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- When you need the work done
- The site address and postcode
- The asbestos register, for older buildings
- What the building is and how it’s used
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or email a schedule or drawings.
Do you need mastic sealing in Colliston?
Much failed sealant was laid on dirty, dusty or damp surfaces. Without clean, sound faces and a primer where the product needs one it comes away from one face.
These are often picked up first by site or facilities staff:
- Water getting in round frames after rain
- Old repairs sealed over failed mastic
- Worn sealant at communal door frames
- Brittle perimeter mastic across a building
Property owners at sites such as Kirkton Industrial Estate, 2 miles to the south-east of Colliston, can have mastic renewed between lettings.
What your quote should include
- Their plan for phasing and protecting the area
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What level of public liability insurance do they hold?
