Oaker Hill New Build Mastic
New build mastic across Oaker Hill and nearby, with old sealant always removed completely.
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Joints pulling apart as timber shrinks
What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
About our new build mastic in Oaker Hill
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on bathrooms & en suites, skirting & floors and plot handovers, and common reasons people get in touch are messy sealant that spoils new finishes and sealant work across a run of new homes.
Older homes in small places like Oaker Hill often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
FAQs for Oaker Hill
Is Oaker Hill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is new build mastic in Oaker Hill guaranteed?
All our work, in Oaker Hill and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Essex.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
How long does the job take?
That depends on the amount of work, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.

What we are called out for in Oaker Hill
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Any of these means the joints need attention:
- New-build shower sealant that has already split
- Sealant work across a run of new homes
- Cracked caulk along new skirting
- Internal frame sealant that has split
For jobs in and around Oaker Hill, choosing the right material for each joint is as important as a tidy finish.

- What product goes in the joint

Aftercare tips
Looking after new joints is easy:
- Keep photos and emails about snagging items
- Check bath and shower seals every few months as the house settles
- Don’t wait for the house to settle if water is getting through
- Open a window or run the fan after bathing
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Early snagging is easier snagging. Left alone, a small crack can become a leak.

Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Oaker Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
