- Weathered mastic on the most exposed windows
- A silicone bead on a sash window that spoils the look
- Tired mastic found when preparing windows for paint
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Look over the window mastic once a year
- Keep modern sealant off the mastic
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
How we handle sand mastic in Manston
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. If you are dealing with a silicone bead on a sash window that spoils the look and mastic dropping out of the joint, we can put it right, on sash and case windows, timber door frames and tenement windows alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Manston is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Around Manston, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Windows and doors in Manston
Manston is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Thanet Parkway station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near St. Catherine's Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Quotes for sand mastic in Manston
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Mould in or behind the old joints
- Any working-time requirements on site
- The product the joint needs
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- If someone has resealed it before
- The problem you’ve noticed
- Photos by email, if that’s easy
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
If you’re 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.
The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a single window, longer for several. Somewhere like Manston needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
Getting a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Advice
Common problems we fix in Manston
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Keep an eye out for these signs:
- Open joints round the window box
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
- Silicone on a period window that looks wrong
If you look after a building such as Newington Community Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Different surfaces, different methods
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
