Mereworth homes and the weather
Historic houses like Old Soar Manor (about 2.5 miles west) are a reminder that the area around Mereworth has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For site and facilities teams at buildings such as Mereworth Community Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Lawrence's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic for homes and businesses in Mereworth
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on tenement windows, sash and case windows and brick reveals, and common reasons people get in touch are gaps round a timber door in stone or brick and failed mastic on an exposed elevation.
Homes in small places like Mereworth 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
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 doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What we’re called out for in Mereworth
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
It’s worth asking for a quote if you see:
- Wind and rain getting in round a sash window
- Cement or filler used on old window joints that has cracked
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
For landlords with property near Wateringbury station, any sash windows need sound mastic to keep draughts and rain out.

Quotes for sand mastic in Mereworth
There’s no set price list, because jobs vary so much. What we look at:
- The product the joint needs
- The number and length of the joints
- Mould in or behind the old joints
- When we can work, for business premises
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
To get a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Leave it or put it right?
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Mereworth can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Questions from Mereworth
Do you work for landlords with property near Wateringbury station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is Mereworth in your area for sand mastic?

How long does the job take?
A typical job takes a few hours per window, depending on the condition of the joints. Your quote will say how long we expect yours to take.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
What sealant work cannot fix
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Timber that has rotted
- Decisions on consent for listed homes
- Damaged stone surrounds
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Stone surrounds
- Timber door frames
- Brick reveals
- Tenement windows
- Period & listed homes
- Sash and case windows
Different surfaces, different methods
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. In a small place like Mereworth, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- 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.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
