DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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 fails, we can still redo it.
Sand mastic in Tillington, done properly
Across Tillington, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, sash and case windows and stone surrounds, and people most often call us about draughts and rain around sash boxes and old cement repairs round a window that have failed.
Mastic can only go onto a dry, clean joint, so window work in Tillington is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, it’s backed by our 12-month guarantee.

How the job changes by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
When to call us in Tillington
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
The most common problems we see are:
- Open joints round the window box
- Failed mastic on an exposed elevation
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
Managing a site like Petworth Cof E Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Frames and glazing around Tillington
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. Historic houses like Petworth House (about 0.8 miles east) are a reminder that the area around Tillington 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.
In the older streets around The Parish Church of All Hallows, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Quotes for sand mastic in Tillington
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- How many rooms, windows or areas are involved
- Access and height
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Tillington: your questions answered
Do you cover Tillington for sand mastic?
Yes, Tillington is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is sand mastic in Tillington guaranteed?
All our work, in Tillington and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Get any rot dealt with first
- Clear gutters so water doesn’t pour onto the windows
- Leave the new mastic unpainted
- Check the mastic when you check the paintwork
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

Why act early in Tillington
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 Tillington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
