Sand mastic for homes and businesses in Newyears Green
Silicone on a period window often looks wrong and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you’re dealing with gaps between timber frames and stone or brick and silicone on a period window that looks wrong, we can put it right, on period & listed homes, sash and case windows and brick reveals alike. Whether you’re looking for a local mastic man, a sealant applicator or a sealant contractor in Newyears Green, that’s what we do.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Newyears Green.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Is parking a problem for a job in Newyears Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

A typical job takes anything from a few hours to a full day, depending on how many windows. Your quote will say how long we expect yours to take.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.

Sand mastic in Newyears Green: local notes
With historic houses such as Ickenham Hall (about 1.5 miles south-east) nearby, there’s older building stock in the area around Newyears Green 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. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
Ickenham Hall, about 1.5 miles south-east, is one of the historic houses in the wider area around Newyears Green, and older homes nearby need a sealant that suits their walls. Newyears Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Rented homes near West Ruislip station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
Newyears Green is about 2 miles west of Ruislip, in Greater London. Anywhere in UB9, we can carry out sand mastic at your property. Across Greater London, we cover 786 places, Newyears Green among them.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
- Plan mastic work ahead of painting
- Find out about consent before window work on a listed home
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Why deal with it now?
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 finishes neatly against the masonry. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Newyears Green.
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear quote for the lot.

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints for a typical job.

- 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.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
