How we handle sand mastic in Row Heath
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. Common call-outs are for mastic worn away on windows facing the weather and mastic round period door frames that has failed, on stone surrounds, tenement windows and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Row Heath is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. For a village or hamlet like Row Heath, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Advice
Common questions in Row Heath
I let a flat near Weeley station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is Row Heath within the area you cover?
Yes. Row Heath is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What guarantee comes with the work?
All our work has a one-year guarantee.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
When it is not the sealant
In fairness, some problems need a different trade:
- Putty and glazing repairs
- Sash cords, weights and draught-proofing of the sashes
- Whether work needs listed building consent
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.
What we seal
- Tenement windows
- Period & listed homes
- Sash and case windows
- Timber door frames
- Stone surrounds
- Brick reveals
Surface by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Row Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Can I do it myself?
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.
Some sealant jobs are within reach of a careful DIYer, 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.
Row Heath homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Thorpe Hall (about 2.5 miles north-east) are a reminder that the area around Row Heath has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Weeley station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Engaines Primary School and Nursery, its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
