How we handle sand mastic in Oakridge
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We are often asked to deal with crumbling sand mastic round a window and old cement repairs round a window that have failed, on timber door frames, tenement windows and stone surrounds.
In a smaller place like Oakridge, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

When to call us in Oakridge
Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.

- Draughts and rain around sash boxes
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
If you let a flat or house near Basingstoke station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a single window, longer for several. In a smaller place like Oakridge, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Don’t paint over the new mastic
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

Oakridge: your questions answered
I let a flat near Basingstoke station. Can you help?

Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we’re fully insured.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic can sit properly.
Where do you work from?
We work from Crawley. Our applicators cover Oakridge, along with the rest of our area.
Why act early in Oakridge
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Oakridge, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we will talk you through it.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
Landlords and agents in Oakridge can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What sand mastic looks like in Oakridge
With historic houses such as The Vyne (about 2.6 miles north) nearby, there’s older building stock in the area around Oakridge 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Ruins Of Chapel Of The Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like The Vyne Community School? Then the mastic around its windows and doors needs looking after like any other building’s.
