- Surfaces are cleaned of building dust and primed where needed.

Advice
New build mastic in Tottenham Green, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We work on kitchens, bathrooms & en suites and windows & doors, and people most often call us about sealant work across a run of new homes and joints pulling apart as timber shrinks.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Tottenham Green and beyond.
Our work is backed for twelve months.

What we are called out for in Tottenham Green
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
It’s worth asking for a quote if you see:
- Cracked sealant around new window and door frames
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Sealant applied over dusty or wet surfaces
Tottenham Green is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

New build mastic in Tottenham Green: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Seven Sisters station, the sealant around baths, showers and frames is worth checking in the first year or two.

FAQs for Tottenham Green
Is parking an issue for new build mastic in Tottenham Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near Seven Sisters station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Can you work from my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. If something is not sealant, we’ll say so.
How long will you be here?
Typically it takes a few hours in a single home. Bigger jobs take longer.
Do you work in Tottenham Green?
Yes, we do. Our applicators work in Tottenham Green.
Are you fully insured?
Yes. We are fully insured.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Wipe joints with warm soapy water
- Do not wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
How we quote for new build mastic

What we need to know
Photos by email are helpful but not essential. Please mention:
- Photos by email, if that’s easy
- Whether it has been sealed before
- Where the job is, and your postcode
- How many joints, rooms or windows are involved

Landlord and commercial work in Tottenham Green
We also work for property managers and facilities teams in Tottenham Green and across Greater London. Several sites can go on one quote, and we are fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
