How we handle sand mastic in Patterton
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on timber door frames, period & listed homes and sash and case windows, and common reasons people get in touch are mastic round period door frames that has failed and mastic dropping out of the joint.
Outdoor sealant needs a dry surface, so window work around Patterton is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Big or small, it’s backed by our 12-month guarantee in Patterton and across East Renfrewshire.

How we quote for sand mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- How easy the joints are to reach
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- How we’d reach the joints
- Any previous sealing or DIY work
- The address or postcode of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Patterton questions

Yes, Patterton is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for landlords with property near Patterton station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.

What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They decide whether consent is needed.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
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.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Frames and glazing around Patterton
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Patterton is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Rented homes near Patterton station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Pollok House, about 2.7 miles north, is one of the historic houses in the wider area around Patterton. Managing a site like Eastwood High School? Then its window and door frames need their mastic kept sound, just like a home’s.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. Outdoor work around Patterton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Clear the area around the work
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

Why it’s worth doing now in Patterton
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
