When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Masonry that has broken away beside the joint
- Materials that need asbestos testing before work
- Misted or failed double-glazed units
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.
What we seal
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
Mastic sealing in Lesmahagow, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have patchy repairs in mismatched sealant and repeated reactive repairs to the same buildings, we can help. Most enquiries from Lesmahagow start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
In smaller Scottish places like Lesmahagow, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Blocks and managed buildings in Lesmahagow
Lesmahagow is on Scotland’s drier eastern side. Frost and condensation on winter mornings can still delay outside mastic.
For a school such as Lesmahagow High School, perimeter mastic on windows and doors is a holiday job. If you are responsible for a building such as Lesmahagow Old Parish Church, frame and door mastic needs the same attention as any other property. If you own or manage units on a site such as Gateside Industrial Estate, which lies south of Lesmahagow, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Lesmahagow: questions and answers
Is Lesmahagow too small for you to travel to?
No. Places such as Lesmahagow are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.
Is Gateside Industrial Estate, near Lesmahagow, within your area?
Yes. We cover Lesmahagow and the area around it, including industrial estates, business parks and retail parks such as Gateside Industrial Estate. Photos and a short description are enough for a first look.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you do block-wide mastic programmes?
We can. We survey and price each building, then work through them in order, and the programme can start with the worst.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

What else we do in Lesmahagow
When to bring in a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Tell us who will meet us and how to get in at your building near Lesmahagow. We’ll confirm the plan with the fixed quote.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Flag any permit to work we will need
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

What sets the cost
Each job is priced on its own details. The main factors are:
- The size and state of each joint
- Working within restricted access windows
- Site requirements such as inductions and permits
- How accessible the joints are
Pricing mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- Any dates the work must fit around
- How the joints are reached, and at what height
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call 01277 525 020 or email the details over if you’d rather talk the job through.
Aftercare for building managers
For the best life from the joints:
- Protect low-level joints in entrances
- Group repairs into a planned programme
- Start inspections with the most exposed faces
- Track which buildings were done and when
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
