Mastic sealing for commercial buildings in New Galloway
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. The enquiries we see most involve estate-wide sealant that is simply worn out and draught complaints from residents or tenants, on communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks. Looking for mastic applicators who cover New Galloway? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For buildings around New Galloway, we group the work to keep travel and visits down. Send addresses and photos for a quote covering the batch.
The 12-month guarantee is for workmanship rather than 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.

Questions we’re asked in New Galloway
Is New Galloway too small for you to travel to?
Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Which documents can you supply for work in New Galloway?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.
Diagnose, treat, sign off

What the job involves on each surface
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
External movement joints
External movement joints take up expansion and contraction. Once that sealant goes, rain can reach the wall.
What we are called out for in New Galloway
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.
Site and facilities staff are often the first to spot these:
- Failed external movement joints
- Occupiers reporting cold air round windows
- Damp patches beside frames
- Mastic failing across several blocks on an estate
For a building around New Galloway, a look at every elevation first shows which joints need renewing now and which can wait.
Before you book anyone
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
- Who will actually carry out the work
- Their plan for phasing and protecting the area
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Track which buildings were done and when
- Check sealant joints during planned building inspections
- Start inspections with the most exposed faces
- Share the asbestos register when you send details
Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Around smaller places like New Galloway, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
