Cost factors for mastic joints
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- How accessible the joints are
- The product specified
- Location, for remote and island sites
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Send us:
- The product your specification calls for
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- Your programme or deadline
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or phone 01277 525 020 or email the details over if you’d rather talk the job through.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Broken glass or failed sealed units
- Substrate edges that need repairing first
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly before you book.
What we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
What we are called out for in Hartwood
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Common reasons buildings call us in:
- Leaks at window and door perimeters
- Open joints in brickwork or panels
- A mix of products and colours from past repairs
- No planned programme for sealant
Buildings close to stations like Hartwood station (to the south-west of Hartwood) are often flats over shops, with frame mastic to keep sound.

Questions about Hartwood
Is a smaller place like Hartwood outside your area?
Not at all. Hartwood is within our area. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Glenburn Industrial Estate, near Hartwood?
Yes, sites like Glenburn Industrial Estate are within our area, along with the rest of Hartwood. A few photos and the unit address let us price the work.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Different surfaces, different methods
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Travel to smaller Scottish places like Hartwood is planned so the job is finished in one visit where possible, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.
- First we look at the mastic on each building and note what needs replacing.
- 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.
- 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.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Send your site hours and access windows
- Make sure the joints can be reached
- Tell staff and tenants when we’ll be in

General trades versus a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
