About our mastic sealing in Copshaw Holm
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells, and the failures we are asked to look at most are repeated reactive repairs to the same buildings and movement joints with sealant missing. A specialist sealant contractor works differently from a general builder: in Copshaw Holm, that means joint design, primers and backing rod as standard.
Travel to smaller places like Copshaw Holm is planned so several buildings can be done on one trip. Send addresses and photos for a quote covering the batch.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Is Copshaw Holm 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. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for mastic across several buildings in and around Copshaw Holm?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How the job changes 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. We’ll confirm the colours available for the specified product.
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
- Leaks from above rather than through a joint
If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we will give you a straight answer.
Surfaces we seal
- External wall and movement joints
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
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, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building near Copshaw Holm, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- 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.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- Arrange parking or a loading space

Why it’s worth doing now in Copshaw Holm
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Cost factors for mastic joints
A fixed quote reflects the actual work. It takes account of:
- Whether the work must be split into stages
- Distance, for remote addresses
- How much there is to seal
- Joint width, depth and condition
Larger quantities, tricky access or phasing 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
The more we know, the firmer the quote. Helpful details to send:
- The product your specification calls for
- Photos of the joints, close up and from further back
- Access details, including height
- The type of building and who uses it
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
