About our sand mastic in Elstead
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on stone surrounds, timber door frames and tenement windows, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and mastic round period door frames that has failed.
Many houses in smaller places like Elstead have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Every job comes with our 12-month guarantee, wherever you are in Surrey.

Elstead: your questions answered
Will you come out to Elstead?
Yes, Elstead is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Milford (Surrey) station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. Parking around Elstead is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Why it’s worth doing now in Elstead
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. Homes in smaller places like Elstead can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What sand mastic looks like in Elstead
Historic houses like Wanborough Manor (about 3.7 miles north-east) are a reminder that the area around Elstead has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St James, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as St James CofE Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Milford (Surrey) station, any sash windows need sound mastic to keep draughts and rain out.
