About our sand mastic in North Hinksey
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. Typical jobs include mastic round period door frames that has failed and modern sealant on a period surround, across sash and case windows, stone surrounds and period & listed homes.
Houses in smaller places like North Hinksey can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
There’s a 12-month guarantee on every job, whatever its size.

Why act early in North Hinksey
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Homes in smaller places like North Hinksey can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

What the job involves on each surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. We rake it out and renew it.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we will confirm what’s needed.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a single window, longer for several, including the tidy-up. In a smaller place like North Hinksey, 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

What else we do in North Hinksey
What we can’t put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Decisions on consent for listed homes
- Broken panes
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Stone surrounds
- Tenement windows
- Sash and case windows
- Brick reveals
- Period & listed homes
- Timber door frames
Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Do not run silicone over sand mastic
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
What we are called out for in North Hinksey
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Most people get in touch when they notice one of these:
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Old sand mastic that has cracked, crumbled or fallen out
Managing a site like North Hinksey Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.

Frames and glazing around North Hinksey
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 Holywell Manor (about 2 miles east) are a reminder that the area around North Hinksey 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.
If you let a flat or house near Oxford station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Peter and St Paul, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
