How we handle sand mastic in Bow Brickhill
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. We work on stone surrounds, brick reveals and period & listed homes, and people most often call us about old cement repairs round a window that have failed and weathered mastic on the most exposed windows.
In a village or hamlet like Bow Brickhill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same 12-month guarantee in Bow Brickhill and across Milton Keynes.

Frames and glazing around Bow Brickhill
With historic houses such as Bletchley Park (about 2.6 miles west) nearby, there’s older building stock in the area around Bow Brickhill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Bow Brickhill station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Bow Brickhill questions
Will you come out to Bow Brickhill?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Bow Brickhill in your area for sand mastic?
Yes. Our work covers London and the South East, and Bow Brickhill is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. Somewhere as small as Bow Brickhill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Clear the area around the work
Ask for a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or drop us an email.

When to call us in Bow Brickhill
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
Signs it’s time to call us include:
- Tired mastic found when preparing windows for paint
- Mastic worn away on windows facing the weather
- Mastic dropping out of the joint
- Modern sealant on a period surround
Managing a site like Bow Brickhill CofE VA Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Are they insured?
- Who does the work, and how experienced they are
- Is the old sealant removed completely?
- How the colour is chosen
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Sash cords, weights and draught-proofing of the sashes
- Damaged stone surrounds
- Broken panes
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Stone surrounds
- Brick reveals
- Tenement windows
- Period & listed homes
- Sash and case windows
- Timber door frames
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Where a wall is exposed, as many are in small places like Bow Brickhill, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.
