Sand mastic in Hanover, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have crumbling sand mastic round a window and weathered mastic on the most exposed windows, we can help, on sash and case windows, brick reveals and period & listed homes alike.
Homes around Hanover range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Landlords, agents and businesses in Hanover

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. In a smaller place like Hanover, 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 start by checking each surround and agreeing the joints to renew.
- 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.
- 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.
Preparing for the visit
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions

Advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Hanover questions
Do you work for landlords with property near Brighton station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Hanover?
Yes, Hanover 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.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
What should I tell you?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we will ask.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Windows and doors in Hanover
Hanover is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of the Annunciation include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Brighton station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
Hanover is about 1 mile south of Brighton, in Brighton and Hove. Across the BN2 area, our applicators can take on sand mastic. Across Brighton and Hove, we cover 30 places, Hanover among them.
Work in BN2, BN1 and BN50 works the same way as everywhere else we cover. Streets in the area include Elmore Road, London Road and Milton Road, all of which we cover. Close by, we work in Brighton (1 mile north), Carlton Hill (1 mile south), West Hill (1 mile west), Seven Dials (1 mile west) and Kemptown (1 mile south-east). We also work in nearby towns such as Brighton and Hove (3 miles west), Aldrington (3 miles west), Hangleton (3 miles north-west), Patcham (3 miles north), Westdene (3 miles north-west) and Saltdean (4 miles south-east). Hanover is among the bigger towns we cover in Brighton and Hove.
Around Hanover
In Hanover, that means homes and buildings near Academy of Creative Training, Brighton Girls and The Dover Castle pub. The nearest railway station is Brighton station, roughly 0.6 miles west of the centre. Well-known places in the area include Old Police Cells Museum (0.8 miles south-west) and Brighton General Hospital (0.6 miles east). Green spaces nearby include Whitehawk Hill and Newmarket Hill.
Why deal with it now?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around Hanover, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

When to call us in Hanover
Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.
The most common problems we see are:
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
- Draughts and rain around sash boxes
- Old sand mastic that has cracked, crumbled or fallen out
If you look after a building such as Elm Grove Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Keeping the joints in good condition
So the new joints stay in good condition:
- Avoid patching sand mastic with silicone
- Don’t paint over the new mastic
- Look over the window mastic once a year
- Clear gutters so water doesn’t pour onto the windows
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
