Sand mastic in Silchester, done properly
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on brick reveals, tenement windows and sash and case windows, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and a silicone bead on a sash window that spoils the look.
Somewhere as small as Silchester, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- The product the joint needs
- Any mould that needs treating
- How much there is to do
- Whether the work is at height
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. Somewhere like Silchester needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Advice
Why it’s worth doing now in Silchester
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Silchester can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.
What you get with us
- Full insurance on every job
- Neat joints and a tidy finish
- Over 20 years’ experience

Silchester: your questions answered
Do you cover smaller places like Silchester?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Bramley (Hants) station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
How long will you be here?
A typical job takes anything from a few hours to a full day, depending on how many windows. We will confirm how long when we quote.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Windows and doors in Silchester
Historic houses like The Vyne (about 3.3 miles south) are a reminder that the area around Silchester has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Saint Luke's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Silchester Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Questions to ask before booking
- How much experience the applicator has
- The length of the guarantee
- What product goes in the joint
- What preparation is included
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
