About our sand mastic in Brookwood
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. Typical jobs include gaps where the frame meets the masonry and silicone on a period window that looks wrong, on sash and case windows, brick reveals and timber door frames.
Somewhere as small as Brookwood, 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.
Your job is guaranteed for a year, as with all our work.

Do you need sand mastic in Brookwood?
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
People generally contact us after spotting one of these:
- Old sand mastic that has cracked, crumbled or fallen out
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
For landlords with property near Brookwood station, older sash windows in a rental need their mastic kept sound to keep the weather out.

How we quote for sand mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- When we can work, for business premises
- The size of the job
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
Helping us quote
Photos help, but a description is a good start. Please mention:
- The type of property
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking

What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Older cottages and farmhouses around Brookwood can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Brookwood homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Brookwood Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Saint Saviour's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the job changes by surface
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Sash cords, weights and draught-proofing of the sashes
- Decisions on consent for listed homes
- Broken panes
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

How to look after the new joints
To keep the joints looking good and working properly:
- Clear gutters so water does not pour onto the windows
- Avoid patching sand mastic with silicone
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

How much does sand mastic cost in Brookwood?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several for a typical job. In a small place like Brookwood, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
