On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. We work on window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints, and the usual reasons a site gets in touch are draughts at frames across a block and damaged joints in communal entrances and corridors. One point of contact handles commercial sealant work in Black Crofts from the first photos to the final walk-round, whether it’s one building or several.

How a job runs
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building near Black Crofts, 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.
- You get a fixed quote, priced per building where that helps your budgeting.
- 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.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Move anything stored against the joints
- Flag any permit to work we’ll need
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Why act early in Black Crofts
Looking at mastic during planned maintenance costs little. Leaving it until there’s a leak turns it into reactive work with less control over timing. For buildings near Black Crofts, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Why choose Mastic Doctor in Black Crofts
- One contact handling all your sites
- RAL and finish matching where the product range allows
- Colour options checked against the specified product
- Work to your specification and the manufacturer’s guidance

When to call us in Black Crofts
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
Look out for the following:
- No planned programme for sealant
- Damaged joints in communal entrances and corridors
- Leaks at window and door perimeters
- Movement joints with sealant missing
If you’re responsible for a building such as Ardchattan Parish Church, frame and door mastic needs the same attention as any other property.

Building owners, agents and FMs in Black Crofts
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
- The size and state of each joint
- Whether old sealant has to be cut out first
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.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- The product your specification calls for
- How the joints are reached, and at what height
- When you need the work done
- Where the site is, with the postcode
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email drawings and photos.
When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Failed window or door frames, which need a window contractor
- Masonry that has broken away beside the joint
- Materials that need asbestos testing before work
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Communal kitchens and washrooms
Block-wide mastic in Black Crofts
Black Crofts is within about 1 mile of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. The west of Scotland, where Black Crofts is, gets more rain than the east. The most exposed elevations need checking most often. Outside mastic goes on in dry spells, with some flexibility in the programme.
Blocks of flats and mixed-use buildings often cluster around stations such as Connel Ferry station, 1.4 miles to the south-west of Black Crofts, and their window and balcony mastic tends to age at the same rate across a building.
Black Crofts is about 40 miles north-west of Helensburgh, in Argyll and Bute. We cover commercial sites throughout Black Crofts. Across Argyll and Bute, 124 places are covered, including Black Crofts. We also cover Glasgow, some 60 miles away.

Common questions from Black Crofts clients
Does a coastal location like Black Crofts affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you quote for a block close to Connel Ferry station?
Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Do you work in Black Crofts?
Yes. We cover Black Crofts, and you can call 01277 525 020 or email us to get started.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Will residents or tenants be disturbed?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
