How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- The type of sealant required
- The size of the job
- Mould in or behind the old joints
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
What to tell us for a quote
When you call or email, it’s useful to know:
- How we’d reach the joints
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Where the job is, and your postcode
If you are in Roybridge and need sand mastic, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Sand mastic in Roybridge, done properly
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Common call-outs are for a silicone bead on a sash window that spoils the look and old sand mastic that has cracked, crumbled or fallen out, across stone surrounds, sash and case windows and period & listed homes.
In and around a place like Roybridge, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In an older home around Roybridge, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What sand mastic looks like in Roybridge
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In the older streets around St Margaret's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What else we do in Roybridge
When it isn’t the sealant
In fairness, some problems need a different trade:
- Planning or listed building consent (your local planning authority decides)
- Masonry that needs repairing
- Broken panes
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Stone surrounds
- Period & listed homes
- Sash and case windows
- Brick reveals
- Timber door frames
- Tenement windows
Do you need sand mastic in Roybridge?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
Keep an eye out for any of the following:
- Failed mastic on an exposed elevation
- Mastic that needs renewing before redecorating
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
Rented homes near Roy Bridge station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before booking
- What product goes in the joint
- When the joint can take water or movement
- What insurance they hold
- The length of the guarantee
Different surfaces, different methods
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
