Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Construction mastic in Craigends
We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. We work on sanitary and kitchen joints, internal decorators’ caulk and window and door perimeters, and the failures we are asked to look at most are a long mastic snag list close to completion and oversized or tapered gaps around new frames. Whoever orders the work in Craigends, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a site around Craigends, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

New build and refits around Craigends
Building work in Craigends comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification. Craigends is in the west of Scotland, the wetter side of the country. External mastic dates are agreed with the site manager, with internal sealant kept ready for wet days.
New units and refits on sites such as Mossedge Industrial Estate (to the south-east of Craigends) need their panel and perimeter joints sealed to the specification. For contractors at a school such as Gryffe High School, sealing has to be finished before term starts.
Craigends is about 2 miles north of Johnstone, in Renfrewshire. Across the PA6 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Signs you need construction mastic in Craigends
On construction sites, joints usually fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
What tends to prompt an enquiry:
- Old sealant on a refurbishment that needs stripping before new work
- A long mastic snag list close to completion
- Internal caulk splitting as the building dries out
- A mastic package split between trades with no clear owner
On a healthcare site such as Merchiston Hospital, 1.2 miles to the south of Craigends, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

FAQs: Craigends
Will you take on work at estates like Mossedge Industrial Estate, close to Craigends?
Yes, sites like Mossedge Industrial Estate are within our area, along with the rest of Craigends. A few photos and the unit address let us price the work.
Is Craigends too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Aftercare for building managers
To get the most from the new sealant:
- Brief following trades on areas that have been sealed
- Flag uneven or tapered frame gaps early
- Ask for joint and product checks before the package is urgent
- Brief the final clean team to avoid blades near sealant
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
