Sand Mastic in Woodham
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for householders, landlords and businesses in Woodham. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- A silicone bead on a sash window that spoils the look
- Old cement repairs round a window that have failed
- Draughts and rain around sash boxes
What we do, step by step
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a single window, longer for several for a typical job. In a smaller place like Woodham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky

Sand mastic in Woodham
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. 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. We work on brick reveals, tenement windows and sash and case windows, and the jobs we see most are tired mastic found when preparing windows for paint and old cement repairs round a window that have failed.
In a smaller place like Woodham, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from Woodham
Will you come out to Woodham?
Yes. Woodham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near West Byfleet station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Honest limits
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Broken panes
- Decayed frames that need repair
- Whether work needs listed building consent
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Tenement windows
- Timber door frames
- Stone surrounds
- Period & listed homes
- Brick reveals
- Sash and case windows
Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the cost of sand mastic
Every job gets its own quote. These are the things that affect it:
- The product the joint needs
- The size of the job
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
Landlord and commercial work in Woodham
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 that we can handle for you.
If you manage several properties in or around Woodham, several properties can go on one quote. Just tell us the addresses and what each one needs.
What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a smaller place like Woodham, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
- Clear gutters so water does not pour onto the windows
- Go gently near the mastic when preparing windows
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
Sand mastic in Woodham: local notes
With historic houses such as Botleys Mansion (about 2.2 miles north-west) nearby, there’s older building stock in the area around Woodham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Fullbrook School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near West Byfleet station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St John the Baptist include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
