Walthamstow Village: your questions answered
Can parking be tricky for a visit in Walthamstow Village?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is Walthamstow Village in your area for new build mastic?
Yes, Walthamstow Village is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
What does new build mastic cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us with a short description of the job.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Do you have insurance?
Yes. We are fully insured for every job we do.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
New build mastic in Walthamstow Village, done properly
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on skirting & floors, plot handovers and kitchens, and the jobs we see most are messy sealant that spoils new finishes and sealant applied over dusty or wet surfaces.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

New build mastic in Walthamstow Village: local notes
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Walthamstow Village can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What else we do in Walthamstow Village
Why it’s worth doing now in Walthamstow Village
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or email us with a few pictures. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Walthamstow Village, the repair is bigger than a sealant job.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Surface by surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
What we’re called out for in Walthamstow Village
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Keep an eye out for any of the following:
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
If you’ve bought a new home near Walthamstow Central station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include

What affects the quote in Walthamstow Village
Your quote is based on your job. We take into account:

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. In a London area like Walthamstow Village, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
