Sand Mastic in Sherington
Problem with your window and door surrounds in Sherington? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Mastic dropping out of the joint
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Sand mastic in Sherington, done properly
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for gaps between timber frames and stone or brick and modern sealant on a period surround, on brick reveals, tenement windows and stone surrounds.
In a village or hamlet like Sherington, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

- How we’d reach the joints

Common problems we fix in Sherington
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
Any of these means the joints need attention:
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
- Open joints round the window box
- Mastic worn away on windows facing the weather
Homes close to Church of St Laud include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Comparing quotes
- The length of the guarantee
- How long to leave it before use
- Whether the sealant suits the joint
- Whether you can choose the colour
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Sherington homes and the weather
Historic houses like Linford Manor (about 3.6 miles south-west) are a reminder that the area around Sherington has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
For site and facilities teams at buildings such as Sherington Church of England School, its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Why it’s worth doing now in Sherington
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Sherington, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
Why us?
- We never seal over old sealant

Common questions in Sherington
Do you cover smaller places like Sherington?
Yes, Sherington is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on sand mastic in Sherington?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we’ll talk you through it.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
