Sand Mastic in Water Stratford
Our applicators work in Water Stratford on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Draughts and rain around sash boxes
Why it’s worth doing now in Water Stratford
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like Water Stratford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

About our sand mastic in Water Stratford
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on timber door frames, sash and case windows and period & listed homes, and the jobs we see most are mastic that needs renewing before redecorating and gaps between timber frames and stone or brick.
In a village or hamlet like Water Stratford, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
What affects the cost of sand mastic
We do not publish a price list. What we look at:
- How much there is to do
- Access and height
- Working hours on commercial sites
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
When you contact us, it’s useful to know:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually. Simply ring 0345 464 0079 or send us an email and describe the job and send pictures if you have them.
Windows and doors in Water Stratford
With historic houses such as Stowe House (about 2.3 miles north-east) nearby, there’s older building stock in the area around Water Stratford as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Giles include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What we do, step by step
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Water Stratford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Common problems we fix in Water Stratford
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Any of these means the joints need attention:
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
- Draughty sash windows at the surround
In and around Water Stratford, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What we cannot put right

Joints and surfaces we work on
- Sash and case windows
- Brick reveals
- Period & listed homes
- Tenement windows
- Stone surrounds
- Timber door frames
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
- Keep sills and gutters clear so water drains away
- Avoid patching sand mastic with silicone
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Questions from Water Stratford
What guarantee comes with sand mastic in Water Stratford?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Water Stratford in your area for sand mastic?
Yes. Our work covers London and the South East, and Water Stratford is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
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.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Are you fully insured?
Yes. Full insurance covers our work.
