Your questions about sand mastic in Hicks Forstal
Does living near the coast affect sand mastic in Hicks Forstal?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Is Hicks Forstal 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.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job, sand mastic included.
What should I tell you?
Tell us what needs doing and where. We will ask anything else we need to know.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
How long does sand mastic take to go off?
Not right away. The skin forms first, and the full set comes later, and we will tell you what to expect.
Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Sand mastic for homes and businesses in Hicks Forstal
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include draughty sash windows at the surround and gaps round a timber door in stone or brick, on tenement windows, sash and case windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Hicks Forstal is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with our 12-month guarantee, wherever you are in Kent.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Looking after it afterwards
To keep the joints looking good and working properly:
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Do not run silicone over sand mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Honest limits
A few problems are outside what sealant work can do:
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
- Masonry that needs repairing
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

How the job changes by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- The amount of work
- Which sealant suits the joint
- When we can work, for business premises
- Mould in or behind the old joints
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What we need to know
There’s no need for technical detail. Just tell us:
- Where the property is
- A few photos by email, if you can
- Access, such as stairs, a lift or height
- If someone has resealed it before
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or drop us an email.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. Somewhere as small as Hicks Forstal, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us if parking is tricky
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

Advice
Why deal with it now?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Hicks Forstal can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Frames and glazing around Hicks Forstal
Hicks Forstal is within about 3 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Sturry station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Spires Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
