About our new build mastic in Crown Wood
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. Typical jobs include new-build shower sealant that has already split and plot mastic for developers ahead of handover, across show homes, windows & doors and skirting & floors.
Homes around Crown Wood range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Do you need new build mastic in Crown Wood?
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Signs it’s time to call us include:
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
- Internal frame sealant that has split
- Shower seals failing in the first year or two
If you’ve bought a new home near Martins Heron station, the sealant around baths, showers and frames is worth checking in the first year or two.

What else we do in Crown Wood
How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. Parking around Crown Wood is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. If you’re unsure which you have, call 0345 464 0079 or email us with pictures. In a smaller place like Crown Wood, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Newer neighbourhoods have been added to Bracknell over the years, so brand-new homes and homes from the post-war decades sit within a short drive of each other.

Crown Wood questions
Do you cover Crown Wood for new build mastic?
Yes. We work across London and the South East, and Crown Wood is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Can you help a landlord with a rental near Martins Heron station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is the work guaranteed?
Yes. All our work carries our one-year guarantee.
How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. We’ll confirm how long when we quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How much does new build mastic cost in Crown Wood?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens suited to the job.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Looking after it afterwards
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with straight away
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day before water reaches them.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Broken tiles or a split tray
- Movement caused by a poorly fitted tray or bath
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
