Eversholt Sand Mastic
Sand mastic across Eversholt and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Old cement repairs round a window that have failed
- Draughts and rain around sash boxes
- Cracked mastic round a front door frame
What happens if it’s left?
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. In a small place like Eversholt, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- 20+ years of sealant experience
- Trusted Arbo and Everbuild sealants

- Every job guaranteed for a year

About our sand mastic in Eversholt
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you’re dealing with mastic dropping out of the joint and modern sealant on a period surround, we can put it right.
In a village or hamlet like Eversholt, 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.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Eversholt: your questions answered
Do you cover smaller places like Eversholt?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Flitwick station?

What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you guarantee sand mastic work?
Every job comes with our one-year guarantee, and we’re fully insured.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you need sand mastic in Eversholt?
Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.
If you can see any of these, it’s time to have the joints looked at:
- Draughts and rain around sash boxes
- Tired mastic found when preparing windows for paint
- Silicone on a period window that looks wrong
- Cement or filler used on old window joints that has cracked
Homes close to Church of St Lawrence include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

How we quote for sand mastic
There’s no set price list. The quote depends on:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Any working-time requirements on site
- How easy the joints are to reach
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- A few photos by email, if you can
- Whether it has been sealed before
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or email us with the details, and photos are welcome.

How to look after the new joints
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Take care around the mastic when scraping paint
- Keep modern sealant off the mastic
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Sand mastic in Eversholt: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Flitwick Manor (about 1.9 miles east) are a reminder that the area around Eversholt has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Flitwick station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
