How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Silver Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed

Advice
Sand mastic for homes and businesses in Silver Street
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on timber door frames, sash and case windows and tenement windows, and people most often call us about gaps where the frame meets the masonry and a silicone bead on a sash window that spoils the look.
Somewhere as small as Silver Street, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What the job involves on each surface
Stone surrounds
The stone is treated with care when the old mastic comes out.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Do you need sand mastic in Silver Street?
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
The problems people normally mention when they call include:
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
Schools such as Bredgar Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How do I get a quote for sand mastic in Silver Street?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email and let us know what needs doing and where.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What affects the quote in Silver Street
Jobs vary more than people expect. The main factors:
- The type of sealant required
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- The number and length of the joints
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
To help us quote quickly, please include:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- The rough size of the job
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved and give you a clear quote.
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Silver Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us

- We are fully insured

Frames and glazing around Silver Street
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.
Rented homes near Sittingbourne station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

For landlords and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Keeping the joints in good condition
Aftercare is simple:
- Don’t run silicone over sand mastic
- Avoid heavy scraping on the mastic joint
- Check with your local planning authority if your home is listed
- Do not paint over the new mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
