Quoting for work in Mountcastle
Each job is priced on its own details. The main factors are:
- Travel to remote or island sites
- The total length or number of joints
- Any access equipment needed
- Backing rod, priming and other preparation
Pricing facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.
Details that help us quote
We can often quote from photos and a few details. It helps to include:
- How the joints are reached, and at what height
- Clear photos of the problem areas
- The asbestos register, for older buildings
- Rough lengths or quantities, or drawings if you have them
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or use the quote form with what you know.
How we handle facade sealing in Mountcastle
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. If you’re dealing with failed seals around shopfront and entrance frames and water coming in around window frames, we can help, whatever the surface. Most enquiries from Mountcastle start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Where new frames meet sandstone or granite in a Scottish city, the sealant has to suit the stone: neutral-cure products that won’t mark the masonry, primed where the maker says, in a colour that sits with it.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Looking after the joints
After handover, a little attention goes a long way:
- Keep pressure washers away from fresh sealant
- Combine resealing with other works that need access
- Confirm the survey covers external sealants in older buildings
- Investigate damp beside windows promptly
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
Why deal with it now?
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. In Mountcastle, as across Scotland, rain finds any gap, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Different surfaces, different methods
Window and door perimeters
Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.

Questions we’re asked in Mountcastle
Is a hospital such as Royal Infirmary of Edinburgh (Little France) somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work around term dates at a campus such as University of Edinburgh - Holyrood Campus?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Common problems we fix in Mountcastle
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
It’s worth sending us details if you spot any of the following:
- Cladding panel joints that have opened up
- Discoloured or dirty facade joints
- Previous reseals run over old sealant
- Perimeter joints where frames meet the structure
On a healthcare site such as Royal Infirmary of Edinburgh (Little France), 2 miles south of Mountcastle, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Sites and facades in and around Mountcastle
Mountcastle lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. A 2-mile radius around Mountcastle takes in a good number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Hotel extensions and refits, at places such as Ellwyn Hotel (under half a mile north of Mountcastle), normally run between busy periods, so the sealing is squeezed into short windows. Building work at universities like University of Edinburgh - Holyrood Campus (1.9 miles west of Mountcastle) is often timed for the summer, mastic included.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a day or two for a few elevations, and longer where access has to be moved around the building. For premises in Mountcastle, tell us about access times, shared entrances and any building rules, and we will plan the work to suit, phased where areas need to stay in use.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Flag any permit to work we’ll need
- Clear stock, furniture or equipment away from the joints
- Point out parking and an unloading spot
