How we handle sand mastic in Penninghame
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you are dealing with mastic that needs renewing before redecorating and old sand mastic that has cracked, crumbled or fallen out, we can help, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Penninghame depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Our work is backed for twelve months.

Common questions in Penninghame
Is there a guarantee on sand mastic in Penninghame?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do sand mastic in Penninghame?
Yes, Penninghame is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Can I choose the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Do you work for landlords and businesses?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Dumfries and Galloway.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Penninghame need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Do you need sand mastic in Penninghame?
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
Common reasons people contact us include:
- Wind and rain getting in round a sash window
- Open joints round the window box
- Cracked mastic round a front door frame
- Mastic dropping out of the joint
Homes close to All Saints Episcopal Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before you book anyone

- What insurance they hold
- How much experience the applicator has
- What guarantee comes with the work
Why act early in Penninghame
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a place like Penninghame, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

What affects the quote in Penninghame
The quote reflects the job in front of us. We take into account:
- Working hours on commercial sites
- Whether the work is at height
- The product the joint needs
- How much there is to do
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Helping us quote
You do not need to know the technical terms. Just tell us:
- What’s wrong with the joints now
- Roughly how big the job is
- Access, such as stairs, a lift or height
- If someone has resealed it before
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.
Work for landlords, hotels and businesses
If you manage several properties in or around Penninghame, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Frames and glazing around Penninghame
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Penninghame 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.
