About our construction mastic in Perth
Mastic tends to be one of the final packages before handover. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Perth. Most enquiries involve perimeter gaps outside the sealant’s range and new external sealant already peeling away, across sanitary and kitchen joints, cladding and panel joints and brick and block movement joints. For commercial sealant work in Perth, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a Scottish town the size of Perth, construction runs from new-build schemes on the edge to refurbishing older stone buildings in the centre. The mastic package changes with the building: harl and render on some, cladding and brick on others.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
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.
Quoting for work in Perth
These are the things that shape the price:
- Specialist products, such as fire-rated or hygienic sealants
- The site’s rules and procedures
- Location, for remote and island sites
- How accessible the joints are
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- The type of building and who uses it
- Your programme or deadline
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
Your questions answered
Will you fit the mastic around our build programme in Perth?
Yes. The mastic is planned around your key stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Perth Royal Infirmary somewhere you can work?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What happens if the weather stops external sealing?
Weather matters for external sealing: each sealant has a temperature range, and the joint must be dry. External work is sequenced with some flexibility.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Signs you need construction mastic in Perth
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Choosing the right product for each joint reduces that.
These are often picked up first by site or facilities staff:
- Inconsistent sealant finishes from plot to plot
- Sealant knocked or painted over by other trades
- Snag items on joints that need redoing before handover
- Missed perimeter joints on a new elevation
For contractors at a school such as Perth High School, sealing has to be finished before term starts.
What your quote should include
- Their public liability cover
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- Their pre-qualification and accreditations

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several buildings in and around Perth can be done on one programme, with one quote. Give us access times for each.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Have the specification and drawings to hand
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we will need

Advice
Facades, frames and programmes in Perth
Building work in Perth comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. The mastic package follows the approved specification. There are plenty of hotels within about 2 miles of Perth. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New units and refits on sites such as St Catherine's Retail Park, under half a mile east of Perth, need their panel and perimeter joints sealed to the specification. Extensions at sites like Perth Royal Infirmary (to the south-west of Perth) normally sit beside working departments, and the mastic follows strict access rules.
Perth is about 33 miles north of Edinburgh, in Perth and Kinross. We cover commercial sites throughout Perth, for single jobs and planned programmes alike. Perth is one of 114 places in Perth and Kinross on our list for mastic packages. Sites around Dundee have their own page, roughly 19 miles from Perth.
Postcode districts covered here: PH1 and PH2 for mastic packages. For a building on Simpson Square, High Street and Moredun Square or nearby, we can quote for mastic packages.

Around Perth

A little further out are Murray Royal Hospital (1.2 miles east) and Balhousie Castle (0.6 miles north-east). Green spaces nearby include St Magdalene's Hill.
Maintenance after handover
For the best life from the joints:
- Ask installers to correct oversized gaps first
- Keep scrapers and abrasive pads off new beads
- Bring the mastic contractor in after the last trades are through
- Get the mastic subcontractor involved early in the programme
Expect some settlement in the first months. The right product in each joint copes with that. We can advise if a joint needs a different product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. 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.
