What affects the quote in East Preston
We do not publish a price list, because jobs vary so much. What we look at:
- The size of the job
- Whether the work is at height
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
When you call or email, these details help:
- If someone has resealed it before

Why it’s worth doing now in East Preston
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around East Preston, 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Windows and doors in East Preston
East Preston is within about 1 mile of 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near The Parish Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like East Preston Infant School? Then its window and door frames need their mastic kept sound, just like a home’s.

Questions from East Preston
Do you cover smaller places like East Preston?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is sand mastic in a coastal place like East Preston any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
How long does sand mastic take?
Most jobs take a few hours per window, depending on the condition of the joints, including preparation and clearing up. Your quote will say how long we expect yours to take.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.

What sealant work can’t fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
- Crumbling stone or brickwork round the window
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
Surfaces we seal
- Brick reveals
- Timber door frames
- Stone surrounds
- Tenement windows
- Period & listed homes
- Sash and case windows
Looking after it afterwards
After the cure time, these simple habits help:
- Get any rot dealt with first
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
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 and timber that stays wet can rot.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for a single window, longer for several. In a smaller place like East Preston, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
