Sand Mastic in Bow Common
We cover Bow Common for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Mastic worn away on windows facing the weather
- Draughts and rain around sash boxes
- Gaps round a timber door in stone or brick
How we handle sand mastic in Bow Common
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you have mastic round period door frames that has failed and patchy fillers round a sash window, we can help, whatever the surface.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
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.

Common problems we fix in Bow Common
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.
If you can see any of these, it’s time to have the joints looked at:
- Draughts and rain around sash boxes
- Modern sealant on a period surround
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
Managing a site like St Paul's Way Trust School? Then its window and door frames need their mastic kept sound, just like a home’s.

Windows and doors in Bow Common
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. With historic houses such as Sutton House (about 2.4 miles north-west) nearby, there’s older building stock in the area around Bow Common as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
As a London address, Bow Common can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near Limehouse station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

FAQs for Bow Common
Can you do sand mastic in Bow Common?
Yes, Bow Common is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is parking an issue for sand mastic in Bow Common?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Should I use sand mastic or silicone?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
How long does the job take?
A typical job takes a few hours for a single window, longer for several. We will confirm how long when we quote.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
How the job changes by surface
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Sashes that need overhauling
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Tenement windows
- Brick reveals
- Stone surrounds
- Timber door frames
- Sash and case windows
- Period & listed homes
Why deal with it now?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before work begins.
