Sand mastic in Roydon Hamlet, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We are often asked to deal with crumbling sand mastic round a window and patchy fillers round a sash window, on timber door frames, stone surrounds and brick reveals.
Outdoor sealant needs dry, clean surfaces, so work on frames around Roydon Hamlet is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. Somewhere as small as Roydon Hamlet, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Where a wall is exposed, as many are in small places like Roydon Hamlet, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Frames and glazing around Roydon Hamlet
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Roydon Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Is sand mastic better than silicone for my windows?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
What should I tell you?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What we are called out for in Roydon Hamlet

If you can see any of these, it’s time to have the joints looked at:
- Crumbling sand mastic round a window
- Mastic worn away on windows facing the weather
- Gaps where the frame meets the masonry
- Old cement repairs round a window that have failed
Letting a property close to Roydon station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

- What happens if they find a problem under the old sealant
- The length of the guarantee
- How the joint is cleaned and prepared
- How long to leave it before use
