New build mastic in Kidmore End
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. Common call-outs are for smeared, uneven beads picked up at snagging and kitchen sealant that has pulled off the wall, on windows & doors, plot handovers and bathrooms & en suites.
Around Kidmore End, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

When to call us in Kidmore End
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
These are the problems we’re asked about most:
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
If you’ve bought a new home near Tilehurst station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Which colour the sealant will be
- Who turns up on the day
- What insurance they hold
- What happens if the job turns out different
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Asking for a quote
Before you ask for a quote, have a think about:
- How we’d reach the joints
- Roughly how big the job is
- Photos by email, if that is easy
- The problem you’ve noticed
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or email us.
Common questions in Kidmore End
Can you do new build mastic in Kidmore End?
Yes, Kidmore End is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Kidmore End?
Yes, Kidmore End is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Why does sealant fail so quickly in new builds?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
How much does new build mastic cost in Kidmore End?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or drop us an email with a short description of the job.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Kidmore End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Landlord and commercial work in Kidmore End
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
How it works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. Somewhere like Kidmore End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
