About our sand mastic in Matching
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on tenement windows, stone surrounds and timber door frames, and the jobs we see most are a silicone bead on a sash window that spoils the look and draughty sash windows at the surround.
Homes in small places like Matching 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.
There’s a 12-month guarantee on every job.

What we do, step by step
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 how much there is to do. In a small place like Matching, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we will explain why.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Sort the mastic before the decorators arrive
- Find out about consent before window work on a listed home
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

- The type of sealant required
- The number and length of the joints
- How many rooms, windows or areas are involved
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What sand mastic looks like in Matching
With historic houses such as Barrington Hall (about 4.1 miles north-east) nearby, there’s older building stock in the area around Matching as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Sawbridgeworth station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around Parish Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
