Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.

Sand mastic in Roberton
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on brick reveals, timber door frames and stone surrounds, and common reasons people get in touch are gaps between timber frames and stone or brick and mastic that needs renewing before redecorating.
Outdoor sealant needs a dry surface, so window work around Roberton is planned around the weather. Let us know about access to every frame, including any upstairs.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we are called out for in Roberton
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Most people get in touch when they notice one of these:
- Open joints round the window box
- Mastic that needs renewing before redecorating
- Weathered mastic on the most exposed windows
- Old cement repairs round a window that have failed
For an older house near a landmark such as Roberton Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are
- Is the old sealant removed completely?
- Are they insured?
Roberton: your questions answered
What guarantee comes with sand mastic in Roberton?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Roberton in your area for sand mastic?
Yes, Roberton is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for a single window, longer for several. We will give you a better idea when we quote.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later, and we will tell you what to expect.
What affects the quote in Roberton
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- Access and height
- The amount of work
- How many areas need sealing
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
- If someone has resealed it before

What else we do in Roberton
Different surfaces, different methods
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The process
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. Outside jobs in Roberton need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Planning or listed building consent (your local planning authority decides)
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
