About our sand mastic in Weedon
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. If you’re dealing with draughty sash windows at the surround and a silicone bead on a sash window that spoils the look, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Weedon is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, whatever its size.

Signs you need sand mastic in Weedon
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
Rented homes near Aylesbury Vale Parkway station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

How we quote for sand mastic
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- How easy the joints are to reach
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
To help us quote quickly, let us know:
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- A few photos by email, if you can
Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Surface by surface
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
How it works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. For a village or hamlet like Weedon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Clear the area around the work
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Advice
Questions from Weedon
Can you help a landlord with a rental near Aylesbury Vale Parkway station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Weedon?
Yes, Weedon is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What guarantee comes with the work?
You get our one-year guarantee to all our work.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you have insurance?
Yes. We are fully insured.
Sand mastic in Weedon: local notes
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 an older house near a landmark such as Old School Room Chapel, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as Old School Room Chapel are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Why it’s worth doing now in Weedon
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Older cottages and farmhouses around Weedon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
