Bolton Sand Mastic
Sand mastic for Bolton and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Failed mastic on an exposed elevation
- Cement or filler used on old window joints that has cracked
- Gaps between timber frames and stone or brick
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Bolton, water from a failed joint in an older stone home can soak into timber and plaster.
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. We take all of that into account in your quote.
Why book with us
- 20+ years of sealant experience
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas
- Arbo and Everbuild products

Sand mastic in Bolton, done properly
We work across Bolton renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. Common call-outs are for weathered mastic on the most exposed windows and window mastic to renew ahead of painting, across tenement windows, period & listed homes and stone surrounds.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Surface by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- Which sealant suits the joint
- Mould in or behind the old joints
- Access and height
- The old material and how stubborn it is
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- A few photos by email, if you can
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, email us at info@mrmastic.co.uk.

Frames and glazing around Bolton
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In the older streets around Bolton Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Is there a guarantee on sand mastic in Bolton?
All our work, in Bolton and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes and newer frames suit modern sealant.
Where do you work from?

How do I get a quote for sand mastic in Bolton?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on how much there is to do. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit

What we are called out for in Bolton
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
If you can see any of these, it’s time to have the joints looked at:
- Draughty sash windows at the surround
- Gaps where the frame meets the masonry
- Mastic that needs renewing before redecorating
- Old cement repairs round a window that have failed
Managing a site like Knox Academy? Then its window and door frames need their mastic kept sound, just like a home’s.
Comparing quotes
- Who turns up on the day
- Whether you can choose the colour
- Are they insured?
- When the joint can take water or movement
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
- Don’t paint over the new mastic
- Don’t run silicone over sand mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
