About our sand mastic in West Street
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Common call-outs are for draughty sash windows at the surround and patchy fillers round a sash window, across tenement windows, timber door frames and brick reveals.
Somewhere as small as West Street, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like West Street, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
Getting a quote
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.
Advice
How the job changes by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Sash cords, weights and draught-proofing of the sashes
- Timber that has rotted
- Putty and glazing repairs
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.

How we quote for sand mastic
Your quote is based on your job. We look at:
- The number and length of the joints
- The old material and how stubborn it is
- Whether the work is at height
- The product the joint needs
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
When you call or email, it’s useful to know:
- Any access issues, like height or stairs
- Photos by email, if that’s easy
- The address or postcode of the job
- What’s wrong with the joints now
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
How to look after the new joints
Aftercare is simple:
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Frames and glazing around West Street
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. Historic houses like Leeds Castle (about 4.2 miles west) are a reminder that the area around West Street has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as The Lenham School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Lenham station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Questions from West Street
Do you cover smaller places like West Street?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do sand mastic in West Street?
Yes, West Street is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later, and we will tell you what to expect.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They decide whether consent is needed.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover West Street, along with the rest of our area.
Is the work guaranteed?
Our 12-month guarantee applies to all our work.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
