How we handle mastic sealing in Closeburn
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Closeburn carry our 12-month guarantee. If you have occupiers reporting cold air round windows and worn sealant at communal door frames, we can help, on shopfronts below residential blocks, balcony and threshold joints and window and door perimeters on blocks alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Closeburn, preparation and product choice get the time they need.
Travel to smaller places like Closeburn is planned so several buildings can be done on one trip. Send addresses and photographs for a quote covering the batch.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Closeburn: questions and answers
Will you price a mastic programme across our Closeburn portfolio?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Is Closeburn too far out for you?
No. Places such as Closeburn are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
How soon can the area be used again?
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.

External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
Signs you need mastic sealing in Closeburn
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Most enquiries start with something like this:
- Repeated reactive repairs to the same buildings
- The same joint failures repeated across a portfolio
- Draughts at frames across a block
- Water getting in round frames after rain
Site managers at schools like Wallace Hall Academy can fit frame mastic into the summer works.

Looking after the joints
To get the most from the new sealant:
- Check sealant joints during planned building inspections
- Protect low-level joints in entrances
- Plan resealing building by building rather than complaint by complaint
- Ask residents or tenants to report leaks and draughts early
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
From enquiry to sign-off
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a day or two for a single block, longer for an estate programme. Tell us who will meet us and how to get in at your building near Closeburn. That goes into the plan alongside the quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
What we need from you
- Agree which areas must stay open
- Tell staff and tenants when we’ll be in
