Sand mastic for Graveney and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
- Failed mastic on an exposed elevation
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sand mastic in Graveney
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 stone surrounds, period & listed homes and tenement windows, and common reasons people get in touch are patchy fillers round a sash window and silicone on a period window that looks wrong.
Outdoor sealant needs dry, clean surfaces, so work on frames around Graveney is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Every job is covered by our 12-month guarantee, wherever you are in Kent.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Your questions about sand mastic in Graveney
Is Graveney within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Faversham station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Where are you based?
We work from Crawley. Our applicators cover Graveney.

How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- Access and height
- The number and length of the joints
- The old material and how stubborn it is
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Graveney homes and the weather
Graveney is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Faversham station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Graveney Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. For a village or hamlet like Graveney, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- The surface is finished to suit the stone or brick.
How to prepare
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Advice
Different surfaces, different methods
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
- Get any rot dealt with first
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Signs you need sand mastic in Graveney
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint and we normally remove them.
The most common problems we see are:
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
What your quote should include
- The length of the guarantee
- When the joint can take water or movement
- What product goes in the joint
- Is the old sealant removed completely?
