Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
What affects the price in Coulter
We price every job individually. The main factors are:
- Any access equipment needed
- The site’s rules and procedures
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Whether an asbestos survey exists
- When you need the work done
- Specification clauses that apply
- Clear photos of the problem areas
Every quote starts with the facts: 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.
Mastic sealing in Coulter, done properly
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. Site teams most often ask us about failed external movement joints and no planned programme for sealant, on balcony and threshold joints, window and door perimeters on blocks and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Coulter, preparation and product choice get the time they need.
For buildings around Coulter, we group the work to keep travel and visits down. Send addresses and photographs for a quote covering the batch.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Coulter: questions and answers
Can you quote for mastic across several buildings in and around Coulter?
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.
Is Coulter too far out for you?
No. Places such as Coulter are covered as much as the big towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Looking after the joints
After handover, a little attention goes a long way:
- Share the asbestos register when you send details
- List the paperwork your organisation requires when you send details
- Prioritise elevations facing the weather
- Ask residents or tenants to report leaks and draughts early
If paintable sealant was used, decoration can follow once it has cured. Silicone usually can’t be painted, so keep decorators off it unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.

Different surfaces, different methods
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler.
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading so the work is phased.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When to call us in Coulter
Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Look out for the following:
- Movement joints with sealant missing
- Leaks at window and door perimeters
- Patchy repairs in mismatched sealant
- Damaged joints in communal entrances and corridors
Trustees of buildings like Culter Parish Church can bring frame and external mastic into a planned maintenance list.
Questions to ask before you book
- Will RAMS and insurance details be available?
- What level of public liability insurance do they hold?
- Their pre-qualification and accreditations
- How the existing material will be dealt with
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building near Coulter, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Point out parking and an unloading spot
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work
