How we handle new build mastic in Oldbury
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We’re often asked to deal with plot mastic for developers ahead of handover and joints pulling apart as timber shrinks, across plot handovers, windows & doors and skirting & floors.
For a small place like Oldbury, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, whatever its size.

How the job changes by surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.

Landlord and commercial work in Oldbury
In hotels, rooms out of use cost money, 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.

How we quote for new build mastic
The quote reflects the job in front of us. We look at:
- Access and height
- Mould in or behind the old joints
- Any working-time requirements on site

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Oldbury, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Wait for the cure time before using a resealed shower
- Avoid scourers and strong chemicals on sealant
- Act quickly if a seal starts to leak
- Keep pictures and emails about snagging items
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
Oldbury questions
I let a flat near Borough Green & Wrotham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Oldbury?
Yes. Oldbury is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Should I wait before resealing?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our one-year guarantee.
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. Around Oldbury, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
