Sand mastic for homes and businesses in Hungerford
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on stone surrounds, timber door frames and sash and case windows, and people most often call us about old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick.
Homes in small places like Hungerford often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. 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.

What we are called out for in Hungerford
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
Any of these means the joints need attention:
- Mastic round period door frames that has failed
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
- Open joints round the window box
Schools such as Waltham St Lawrence Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Are they insured?
- Whether you can choose the colour
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Take care around the mastic when scraping paint
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
- Make sure water runs off the sill
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Hungerford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

What affects the cost of sand mastic
We don’t publish a price list. What we look at:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- When we can work, for business premises
- The product the joint needs
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- The rough size of the job
- How we’d reach the joints
- What’s wrong with the joints now
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Hungerford: your questions answered
Will you come out to Hungerford?
Yes, Hungerford is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Twyford station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we will advise.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
