When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Broken panes
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

Sand mastic for homes and businesses in Aldwych
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. Common call-outs are for draughts and rain around sash boxes and silicone on a period window that looks wrong, across tenement windows, timber door frames and period & listed homes.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first.
All of our work is guaranteed for twelve months, in Aldwych and everywhere else we cover.

Common problems we fix in Aldwych
Timber frames move with the seasons. The movement cracks the mastic over time.
It’s worth asking for a quote if you see:
- Cement or filler used on old window joints that has cracked
- Gaps round a timber door in stone or brick
- Window mastic to renew ahead of painting
- Failed mastic on an exposed elevation
For an older house near a landmark such as St Mary le Strand, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we quote for sand mastic
You will get a clear quote before work begins. It takes into account:
- When we can work, for business premises
- How much there is to do
- Mould in or behind the old joints
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
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 are ready, call 0345 464 0079 or drop us an email.
What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. In Aldwych, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

What sand mastic looks like in Aldwych
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Aldwych is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as St Clement Danes CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Aldwych is about 1 mile north-west of London, in Greater London. From the centre of Aldwych to the outskirts, we cover sand mastic for every kind of property, from flats and houses to offices and hotels. Aldwych is one of 764 towns and villages in Greater London where we work.

Why act early in Aldwych
An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.
