Why it’s worth doing now in Worton
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Worton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Sand mastic for homes and businesses in Worton
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include mastic that needs renewing before redecorating and mastic round period door frames that has failed, on sash and case windows, timber door frames and period & listed homes.
Homes in small places like Worton 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.

Sand mastic in Worton: local notes
With historic houses such as Blenheim Palace (about 3 miles north) nearby, there’s older building stock in the area around Worton as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Peter include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Hanborough station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Worton questions
Will you come out to Worton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Worton in your area for sand mastic?
Yes, Worton is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Should I use sand mastic or silicone?
It depends on the window. Period windows in stone or brick usually suit sand mastic and newer frames usually get a flexible sealant.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.

DIY sealant or a professional job?
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 does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Common problems we fix in Worton
Rain on the window surround works into any crack and pushes it out. Exposed elevations normally fail first.
Signs it’s time to call us include:
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
- Mastic worn away on windows facing the weather
Schools such as St Peter's Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Whether the sealant suits the joint
- What the quote includes, VAT included or not
- What preparation is included
- How long to leave it before use
Aftercare tips
Good habits help new joints last longer. Our tips:
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Do not paint over the new mastic
- Keep modern sealant off the mastic
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
