How we handle new build mastic in Kent Street
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on kitchens, windows & doors and plot handovers, and common reasons people get in touch are internal frame sealant that has split and new-build shower sealant that has already split.
Around Kent Street, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, large or small.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look at the sealant regularly in the first couple of years
- Do not seal over failed sealant yourself
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
How we quote for new build mastic
We do not publish a price list. The quote depends on:
- How many rooms, windows or areas are involved
- Access and height
- How much old sealant there is and how hard it is to remove
- The type of sealant required
Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Whether it has been sealed before
- Any access issues, like height or stairs
- The address or postcode of the job
- A few pictures by email, if you can
To get a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Common questions in Kent Street
Will you come out to Kent Street?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Kent Street for new build mastic?
Yes, Kent Street is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Who should fix failed sealant in a new build?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
How long does new build mastic take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer, and we will say how long yours will take.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.
New homes and floors in Kent Street

Common problems we fix in Kent Street
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
These are the problems we’re asked about most:
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
Around Kent Street, as everywhere, new build mastic is only as good as the preparation behind it.
