Sand mastic for sash & case windows in Bassett, Southampton

- Mastic dropping out of the joint
Sand mastic for homes and businesses in Bassett
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. Common call-outs are for draughty sash windows at the surround and cement or filler used on old window joints that has cracked, across stone surrounds, tenement windows and brick reveals.
Houses in smaller places like Bassett can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Each job carries a 12-month guarantee.

Quotes for sand mastic in Bassett
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Working hours on commercial sites
- How many areas need sealing
- How much there is to do
- Which sealant suits the joint
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- The problem you’ve noticed
- Whether it’s a home or a business
- Photos by email, if that’s easy
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved and give you a clear price.
Do you need sand mastic in Bassett?
Rain on the window surround works into any crack and pushes it out. Exposed elevations generally fail first.
These are the problems we are asked about most:
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Open joints round the window box
- Wind and rain getting in round a sash window
Letting a property close to Swaythling station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Windows and doors in Bassett
Bassett is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Michael and All Angels Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Cantell School? Then the mastic around its windows and doors needs looking after like any other building’s.

Surface by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Crumbling stone or brickwork round the window
- Decisions on consent for listed homes
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

Common questions in Bassett
Do you cover smaller places like Bassett?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Swaythling station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer.
Is the work guaranteed?
All our work has a 12-month guarantee, and we’re fully insured.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
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.

Aftercare tips
Aftercare is simple:
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Don’t paint over the new mastic
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
