Greenfaulds: your questions answered
Can you do sand mastic in Greenfaulds?
Yes, Greenfaulds is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Do you work for landlords with property near Greenfaulds station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you replace silicone on a period window with sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Where do you work from?
We work from Crawley. Our applicators cover Greenfaulds, along with the rest of our area.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
Sand mastic in Greenfaulds
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with wind and rain getting in round a sash window and modern sealant on a period surround, we can help.
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.
All of our work is guaranteed for twelve months, in Greenfaulds and everywhere else we cover.

What we can’t put right
It helps to know what we cannot do:

Frames and glazing around Greenfaulds
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Schools such as Greenfaulds High School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St Mungo's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Around Greenfaulds
Around Greenfaulds, our work takes us to homes and buildings near The Carrick Stone pub and the streets around them. Greenfaulds has its own railway station: Greenfaulds station.

Why deal with it now?
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. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Outside jobs in Greenfaulds 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 is not affected.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Advice
Can I do it myself?
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
