Questions from Maldon
Do you cover Maldon for sand mastic?
Yes. Our work covers London and the South East, and Maldon is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is there a guarantee on sand mastic in Maldon?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Should I use sand mastic or silicone?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We will tell you when we quote.
Sand mastic in Maldon, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. We’re often asked to deal with gaps between timber frames and stone or brick and wind and rain getting in round a sash window, on brick reveals, stone surrounds and sash and case windows.
Around Maldon, many houses have gained conservatories, French doors or replacement windows over time. Each one adds more joints to look after, and those joints age at different rates. Leaks generally start at a sill, a frame head or a glazing joint.
Whatever the size of the job, you get the same 12-month guarantee in Maldon and across Essex.
The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. A visit in Maldon needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

- How much there is to do
- The number of rooms or windows
- Access and height
- Any working-time requirements on site
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

When you contact us, these details help:
- If someone has resealed it before

What we’re called out for in Maldon
Timber frames move with the seasons. The movement cracks the mastic little by little.
Common reasons people contact us include:
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
- Open joints round the window box
- Tired mastic found when preparing windows for paint
If you look after a building such as Maldon Primary School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- What insurance they hold
- Whether you can choose the colour
- Whether the sealant suits the joint
- Whether VAT is included
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Have rotten timber repaired before new mastic goes in
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
Maldon homes and the weather
Maldon 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. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
