Why act early in New Trows
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around New Trows before they leak.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

How we handle mastic sealing in New Trows
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on balcony and threshold joints, shopfronts below residential blocks and external wall and movement joints, and what we are called in for most is failed external movement joints and water getting in round frames after rain. Most enquiries from New Trows start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Outside mastic in Scotland needs dry joints and the right temperature, so work around New Trows is planned with the forecast. We agree a window with some flexibility.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Planned mastic for New Trows portfolios
The east of Scotland, where New Trows is, gets less rain than the west. Cold mornings still limit when outside mastic can go on. We plan block programmes with some give for it
Site managers at schools like Lesmahagow High School can fit frame mastic into the summer works. Churches, halls and community buildings such as Lesmahagow Old Parish Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If you own or manage units on a site such as Gateside Industrial Estate, 0.6 miles to the east of New Trows, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Your questions answered
Is a smaller place like New Trows outside your area?
Not at all. New Trows is within our area. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you price a mastic programme across our New Trows portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we will give a fixed quote.
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.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
How long does a typical visit take?
It depends on the scope, but the work usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints.

Surface by surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
If you are not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
