Sand mastic in Plaistow Green, done properly
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. If you are dealing with cement or filler used on old window joints that has cracked and mastic worn away on windows facing the weather, we can put it right, on tenement windows, timber door frames and stone surrounds alike.
Somewhere as small as Plaistow Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Plaistow Green questions
Is Plaistow Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Plaistow Green in your area for sand mastic?
Yes. We work across London and the South East, and Plaistow Green is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Do you have insurance?
Yes. Mr Mastic is fully insured.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
How the visit works
We keep the work tidy and contained to the area we are working on. The job generally takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. In a small place like Plaistow Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Advice
What affects the quote in Plaistow Green
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- Which sealant suits the joint
- The number of rooms or windows
- The old material and how stubborn it is
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- How we’d reach the joints
- Any previous sealing or DIY work
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sand mastic in Plaistow Green: local notes
Historic houses like St Leonard's Hill (about 2.5 miles north-east) are a reminder that the area around Plaistow Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Ascot station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Work for landlords, hotels and businesses
Landlords and agents in Plaistow Green can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Why it’s worth doing now in Plaistow Green
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around Plaistow Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What we are called out for in Plaistow Green
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Any of these means the joints need attention:
- Silicone on a period window that looks wrong
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
Schools such as Cranbourne Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
