Mastic sealing across Callander
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
From enquiry to sign-off
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Travel to smaller Scottish places like Callander is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Tell us which areas need to stay in use
- Tell staff and tenants when we will be in
- Send your site hours and access windows
Ask for a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
How we handle mastic sealing in Callander
For blocks and buildings in Callander and across Stirling, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. We work on window and door perimeters on blocks, communal kitchens and washrooms and shopfronts below residential blocks, and the failures we are asked to look at most are patchy repairs in mismatched sealant and damaged joints in communal entrances and corridors. Most enquiries from Callander start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Outside mastic in Scotland needs dry joints and the right temperature, so work around Callander is planned with the forecast. Programmes allow for the weather.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Masonry that has broken away beside the joint
- Failed window or door frames, which need a window contractor
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer before you book.

General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Surface by surface
External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
Estate-wide resealing programmes
Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.

Questions about Callander
Will you price a mastic programme across our Callander portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
What paperwork can you provide for a job in Callander?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.

Common problems we fix in Callander
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Things that typically lead to an enquiry:
- Leaks at window and door perimeters
- Estate-wide sealant that is simply worn out
- Worn sealant at communal door frames
- Movement joints with sealant missing
Site managers at schools like McLaren High School can fit frame mastic into the summer works.
Questions to ask before you book
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
- Is the sealant right for the movement and the substrate?
- Whether old or failed sealant will be cut out, not overlaid
