Sand mastic in Marlow Bottom, done properly
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. If you’re dealing with failed mastic on an exposed elevation and mastic that needs renewing before redecorating, we can help, on period & listed homes, stone surrounds and timber door frames alike.
In a village or hamlet like Marlow Bottom, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. Somewhere like Marlow Bottom needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracked or broken glass
- Sashes that need overhauling
- Decisions on consent for listed homes
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Different surfaces, different methods
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
When to call us in Marlow Bottom
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.
Look out for any of the following:
- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
- Mastic dropping out of the joint
- Failed mastic on an exposed elevation
Homes close to St Mary the Virgin include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- How long the guarantee is
- How much experience the applicator has

Windows and doors in Marlow Bottom
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. Historic houses like Harleyford Manor (about 2.8 miles south-west) are a reminder that the area around Marlow Bottom 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’s traditional sand mastic.
Schools such as Burford School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Marlow station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Marlow Bottom questions
Can you help a landlord with a rental near Marlow station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Marlow Bottom?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames normally get a flexible sealant.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Why act early in Marlow Bottom
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Marlow Bottom, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
