DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
New build mastic in Hill Brow, done properly
Across Hill Brow, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. Common call-outs are for skirting joints opening in the first winter and plot mastic for developers ahead of handover, on bathrooms & en suites, windows & doors and skirting & floors.
Around Hill Brow, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Your job is guaranteed for a year, as with all our work.

Your questions about new build mastic in Hill Brow
Do you cover Hill Brow for new build mastic?
Yes, Hill Brow is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
I let a flat near Liss station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
How long does new build mastic take?
That depends on how much there is to do, but most jobs take a few hours in a single home. We’ll give you a better idea when we quote.
Do you have insurance?
Yes. We are fully insured.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Where is Mr Mastic based?
We work from Crawley. We cover Hill Brow and the rest of Hampshire.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Photograph failed sealant before it’s redone
- Do not seal over failed sealant yourself
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
New homes and floors in Hill Brow
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
How it works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Hill Brow needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
