Sand mastic for homes and businesses in Long Hanborough
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We work on tenement windows, stone surrounds and brick reveals, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes.
Houses in smaller places like Long Hanborough can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Long Hanborough homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Blenheim Palace (about 1.9 miles north-east) nearby, there’s older building stock in the area around Long Hanborough 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.
Managing a site like Hanborough Manor CofE School? Then larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Christ Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Combe station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Why it’s worth doing now in Long Hanborough
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a smaller place like Long Hanborough, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Can I add another job to the visit?

Will you leave a mess?

Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How much does sand mastic cost in Long Hanborough?

What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Avoid heavy scraping on the mastic joint
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
Quotes for sand mastic in Long Hanborough
There’s no set price list. The quote depends on:
- The old material and how stubborn it is
- When we can work, for business premises
- Any mould that needs treating
- The type of sealant required
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints. In a smaller place like Long Hanborough, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Mention if the joints have been sealed before
How to get a quote

DIY versus a professional finish
If you’re 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 fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
