New build mastic in Newell Green, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. If you have worktop and upstand sealant coming away and sealant work across a run of new homes, we can put it right, whatever the surface.
For a small place like Newell Green, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Every job is covered by a 12-month guarantee, wherever you are in Bracknell Forest.

Do you need new build mastic in Newell Green?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
The problems people usually mention when they call are:
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
For new homes near Bracknell station, it’s worth checking the sealant early, while snags are still fresh.

Landlord and commercial work in Newell Green
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How the job changes by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Newell Green: your questions answered
Can you do new build mastic in Newell Green?
Yes, Newell Green is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Can you help a landlord with a rental near Bracknell station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Keeping the joints in good condition
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with right away
- Record problems with dated photos
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
What affects the cost of new build mastic
You will get a clear quote before any work starts. It’s based on:
- The number and length of the joints
- The number of rooms or windows
- Whether the work is at height
- Any mould that needs treating
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Whether it has been sealed before
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
