Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Sand mastic for homes and businesses in Great Burstead
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. We work on period & listed homes, stone surrounds and tenement windows, and common reasons people get in touch are tired mastic found when preparing windows for paint and old cement repairs round a window that have failed.
Somewhere as small as Great Burstead, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in Great Burstead as everywhere else we work.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It normally takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Great Burstead, 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.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Advice
Keeping the joints in good condition
Looking after new joints is easy:
- Go gently near the mastic when preparing windows
- Get any rot dealt with first
- Avoid patching sand mastic with silicone
- Keep sills and gutters clear so water drains away
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Your questions about sand mastic in Great Burstead
Can you do sand mastic in Great Burstead?
Yes. We work across London and the South East, and Great Burstead is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Will you come out to Great Burstead?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
When will the new mastic be hard?
Not straight away. It skins first and hardens fully later and we’ll give you an idea for your job.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Honest limits
We will not take on work that will not last, so these are the limits:
- Decayed frames that need repair
- Damaged stone surrounds
- Sashes that need overhauling
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

What sand mastic looks like in Great Burstead
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. Historic houses like Ingatestone Hall (about 4.6 miles north-west) are a reminder that the area around Great Burstead has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Billericay station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Mary Magdalene, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like St Peter's Catholic Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
