Sand mastic in Sevenoaks, done properly
We work across Sevenoaks renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on sash and case windows, timber door frames and tenement windows, and people most often call us about silicone on a period window that looks wrong and old cement repairs round a window that have failed.
In a town like Sevenoaks, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Windows and doors in Sevenoaks
With historic houses such as Knole House (about 1.3 miles south-east) nearby, there’s older building stock in the area around Sevenoaks as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Sevenoaks station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in. Schools such as Sevenoaks Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

FAQs for Sevenoaks
Is sand mastic in Sevenoaks guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you help a landlord with a rental near Sevenoaks station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Do you work in Sevenoaks?
Yes, we do. Sevenoaks is part of the area we cover.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. In Sevenoaks, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Advice
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- How many areas need sealing
- The number and length of the joints
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
When you call or email, it’s useful to know:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- Where the property is
- Whether it has been sealed before
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job, and pictures are welcome.
Looking after it afterwards
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.
