Mastic sealing in Garthamlock
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. Most enquiries involve open joints in brickwork or panels and complaints coming in block by block, across balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks. Facilities teams, main contractors and managing agents in Garthamlock tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Garthamlock is planned with the forecast. Programmes allow for the weather.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Looking after buildings in and around Garthamlock
Garthamlock is in the west of Scotland, the wetter side of the country. The weather side of a block normally needs attention first. External work is booked for dry spells, with a little give in the dates.
If you own or manage units on a site such as Queenslie Industrial Estate, under half a mile south of Garthamlock, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If you manage student housing near a university such as University of Strathclyde (2.2 miles west of Garthamlock), the summer turnaround is the time for mastic. Churches, halls and community buildings such as Saint Benedict's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Garthamlock is about 4 miles south of Lenzie, in Glasgow. Anywhere in G33, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 171 places in Glasgow.

FAQs: Garthamlock
Can you quote for a block close to Stepps station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Does your area include sites such as Queenslie Industrial Estate, near Garthamlock?
Yes. Our area takes in Garthamlock and its surroundings, with estates and business parks such as Queenslie Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
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. Indoors, the weather is rarely a problem.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Start inspections with the most exposed faces
- Reduce knocks to communal area joints
- Include mastic in your cyclical inspections
- Track which buildings were done and when
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
On site: what to expect
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, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Where we can, we combine work around Garthamlock with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.
- 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.
- We check the finished work and confirm the guarantee.
Before we start on site
- Have the specification and drawings to hand
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs

General trades versus a specialist
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.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
How the quote is worked out
Before we quote, we look at:
- Backing rod, priming and other preparation
- The product specified
- Site requirements such as inductions and permits
- Whether the work must be split into stages
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Any dates the work must fit around
- The postcode of the building
The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email us to discuss it first.
