For landlords 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.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
How we handle sand mastic in Holytown
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on sash and case windows, stone surrounds and timber door frames, and people most often call us about mastic round period door frames that has failed and draughts and rain around sash boxes.
In and around a place like Holytown, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Keep sills and gutters clear so water drains away
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
- Inspect the joints round the windows every year or so
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Putty and glazing repairs
- Masonry that needs repairing
- Sashes that rattle, stick or won’t open
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints from start to finish. For a place like Holytown, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work

Advice
Do you need sand mastic in Holytown?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
People normally contact us after spotting one of these:
- Window mastic to renew ahead of painting
- Old cement repairs round a window that have failed
- Weathered mastic on the most exposed windows
- Old sand mastic that has cracked, crumbled or fallen out
If you let a flat or house near Holytown station, any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- The length of the guarantee
- Who does the work, and how experienced they are
- When the joint can take water or movement
- What product goes in the joint
DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Your questions about sand mastic in Holytown
Can you help a landlord with a rental near Holytown 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.
Do you cover smaller places like Holytown?
Yes, Holytown is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we will advise.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then drop us a line at info@mrmastic.co.uk.
What the job involves on each surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Windows and doors in Holytown
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Cambusnethan House (about 4.5 miles south) nearby, there’s older building stock in the area around Holytown as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Brannock High School? Then larger buildings have plenty of frames, and the mastic around each one ages. Historic houses such as Cambusnethan House, about 4.5 miles south, show how far back building around Holytown goes, and older homes nearby need a sealant that suits their walls.
