What new build mastic looks like in Tottenham Hale
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Tottenham Hale station, the sealant around baths, showers and frames is worth checking in the first year or two. Tottenham Hale is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How we handle new build mastic in Tottenham Hale
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on show homes, kitchens and bathrooms & en suites, and the jobs we see most are gaps between new skirting and floors and plot mastic for developers ahead of handover.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
All our work comes with a one-year guarantee.

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Windows & doors
- Skirting & floors
- Bathrooms & en suites
- Kitchens
- Plot handovers
- Show homes
Aftercare tips
Aftercare is simple:
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
- Photograph failed sealant before it’s redone
- Open a window or run the fan after bathing
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Common questions in Tottenham Hale
Is Tottenham Hale in your area for new build mastic?
Yes. Our work covers London and the South East, and Tottenham Hale is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Is parking a problem for a job in Tottenham Hale?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
How long does the job take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer, and we’ll say how long yours will take.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Can I do it myself?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What affects the quote in Tottenham Hale
Jobs vary more than people expect. The main factors:
- The size of the job
- How many areas need sealing
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Helping us quote
To make quoting easier, please include:
- Any access issues, like height or stairs
- Pictures of the joints, sent by email

Landlord and commercial work in Tottenham Hale
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours in a single home. In Tottenham Hale, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height

Leave it or put it right?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Tottenham Hale.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
