Bramshill questions
I let a flat near Winchfield station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Bramshill within the area you cover?
Yes, Bramshill is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Sand mastic in Bramshill, done properly
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. Common call-outs are for patchy fillers round a sash window and mastic round period door frames that has failed, on tenement windows, stone surrounds and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Bramshill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Your job is guaranteed for a year, as with all our work.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. In a small place like Bramshill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

What the job involves on each surface
Stone surrounds
The stone is treated with care while raking out the old mastic.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we’ll confirm what’s needed.
Frames and glazing around Bramshill
Historic houses like Stratfield Saye House (about 2.8 miles west) are a reminder that the area around Bramshill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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 Mission Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Winchfield station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- How much there is to do
- Any working-time requirements on site
- Whether the work is at height
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 will explain the quote if you ask.
Asking for a quote
To make quoting easier, let us know:
- Any previous sealing or DIY work
- Roughly how big the job is
- How we’d reach the joints
- Where the property is
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Avoid patching sand mastic with silicone
- Keep sills and gutters clear so water drains away
- Sort the mastic before the decorators arrive
- Ask a joiner to look at soft timber first
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
