Sand mastic for homes and businesses in Craigmore
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead and we will explain which is best for yours. We work on sash and case windows, brick reveals and timber door frames, and people most often call us about window mastic to renew ahead of painting and wind and rain getting in round a sash window.
In and around a place like Craigmore, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
You get a one-year guarantee, the same in Craigmore as everywhere else we work.

Somewhere like Craigmore may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit

Common problems we fix in Craigmore
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Draughty sash windows at the surround
- Open joints round the window box
If you look after a building such as Rothesay Academy, the mastic around its windows and doors needs looking after like any other building’s.

FAQs for Craigmore
Will you come out to Craigmore?
Yes. Craigmore is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Craigmore affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints. We will confirm how long when we quote.
How do I get a quote for sand mastic in Craigmore?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you offer different sealant colours?
In most cases you can choose. We’ll explain which colours are available.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around Craigmore, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
For anyone letting property in or around Craigmore, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- Mould in or behind the old joints
- The product the joint needs
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Roughly how big the job is
- If someone has resealed it before
- The type of property
- What’s wrong with the joints now
Every job is quoted individually, so start by telling us what you need. Simply send an email to info@mrmastic.co.uk and describe the job, and photos are welcome.
Frames and glazing around Craigmore
Craigmore is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Homes close to Trinity Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Clear gutters so water doesn’t pour onto the windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
