New build mastic in Vernham Street
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you are dealing with leaking shower tray seals in a new home and gaps between new skirting and floors, we can put it right.
For a small place like Vernham Street, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. In a small place like Vernham Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in

Why it’s worth doing now in Vernham Street
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Vernham Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
Why Vernham Street clients choose us
- ARBOMaster approved applicator
- White, clear, grey or coloured to suit, where the product allows

How the job changes by surface
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
What we cannot put right
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Disputes or warranty claims with your builder
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Looking after it afterwards
Aftercare is simple:
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- 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
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
