Sand Mastic in Hydestile
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for householders, landlords and businesses in Hydestile. Fully insured, ARBOMaster approved and guaranteed for a year.
- Cracked mastic round a front door frame
- Mastic dropping out of the joint
- Weathered mastic on the most exposed windows
How we handle sand mastic in Hydestile
Across Hydestile, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. If you’re dealing with patchy fillers round a sash window and draughty sash windows at the surround, we can help.
Around Hydestile, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
What we’re called out for in Hydestile
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
- Draughty sash windows at the surround
- Mastic that needs renewing before redecorating
Homes close to Hambledon Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
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 fails, we can still redo it.
Hydestile homes and the weather
With historic houses such as Loseley Park (about 4.1 miles north) nearby, there’s older building stock in the area around Hydestile as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Milford (Surrey) station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like St Dominic's School? Then its window and door frames need their mastic kept sound, just like a home’s.

Hydestile: your questions answered
Do you work for landlords with property near Milford (Surrey) station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Hydestile?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
How it works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to a full day, depending on how many windows in most cases. Somewhere as small as Hydestile, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- 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.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Clear the area around the work
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or send us an email.
Advice
Different surfaces, different methods
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep modern sealant off the mastic
- Inspect the joints round the windows every year or so
- Avoid heavy scraping on the mastic joint
- Leave the new mastic unpainted
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
What happens if it’s left?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Hydestile, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
