Windows and doors in Lowford
Lowford is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Bursledon station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near St Paul’s Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

About our sand mastic in Lowford
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. Common call-outs are for a silicone bead on a sash window that spoils the look and crumbling sand mastic round a window, across brick reveals, stone surrounds and period & listed homes.
Around Lowford, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Our work is backed for twelve months, in Lowford and everywhere else we cover.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How the job changes by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean.

Common questions in Lowford
Is Lowford within the area you cover?
Yes. Lowford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Lowford affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. If you are redecorating the window, ask us first and we’ll talk you through it.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Looking after it afterwards
Aftercare is simple:
- Do not paint over the new mastic
- Go gently near the mastic when preparing windows
- Do not run silicone over sand mastic
- Check the mastic when you check the paintwork
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What we are called out for in Lowford
Timber frames move with the seasons. The movement cracks the mastic little by little.
Signs it’s time to call us include:
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Silicone on a period window that looks wrong
If you look after a building such as Bursledon Church of England Infant School, the mastic around its windows and doors needs looking after like any other building’s.
