Sand mastic in Marlow Common
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We are often asked to deal with old sand mastic that has cracked, crumbled or fallen out and gaps where the frame meets the masonry, across brick reveals, timber door frames and sash and case windows.
Homes in small places like Marlow Common often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same one-year guarantee in Marlow Common and across Buckinghamshire.

Marlow Common: your questions answered
Is Marlow Common within the area you cover?
Yes, Marlow Common 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.
Do you cover Marlow Common for sand mastic?
Yes. We work across London and the South East, and Marlow Common is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.

How we quote for sand mastic
For a quick quote, just ask. The main things that affect it are:
- When we can work, for business premises
- How much there is to do
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- The type of property
- A few pictures by email, if you can
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What happens if it’s left?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Older cottages and farmhouses around Marlow Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Marlow Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand, and we will take it from there.
