How we handle new build mastic in Temple Mills
Across Temple Mills, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. Common call-outs are for cracked caulk along new skirting and cracked sealant around new window and door frames, on kitchens, windows & doors and show homes.
From brand-new flats to converted terraces with new flooring, London has every kind of floor. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots. In a London area like Temple Mills, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Looking after it afterwards
So the new joints stay in good condition:
- Keep photos and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
- Clean sealant with mild detergent, not abrasives
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.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
Why it’s worth doing now in Temple Mills
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Do you need new build mastic in Temple Mills?
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening as the house dries out and settles
- Cracked caulk along new skirting
- Sealant that never bonded to the surface
- Shower seals failing in the first year or two
If you’ve bought a new home near Stratford International station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- How much experience the applicator has
- What the cure time is
How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
New build mastic around Temple Mills
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
