New build mastic for homes and businesses in West Hackney
Across West Hackney, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. If you’re dealing with kitchen sealant that has pulled off the wall and sealant applied over dusty or wet surfaces, we can put it right.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
Big or small, you get the same one-year guarantee in West Hackney and across Greater London.

Honest limits
We will always be straight with you, so here’s what sealant cannot fix:
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
What we seal
- Bathrooms & en suites
- Plot handovers
- Windows & doors
- Kitchens
- Skirting & floors
- Show homes
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep pictures and emails about snagging items
- Use the extractor fan every time you shower
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
Do not stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
What we are called out for in West Hackney
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Joints pulling apart as timber shrinks
For new homes near Rectory Road station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- What product goes in the joint
- When the joint can take water or movement
- Whether VAT is included
- How much experience the applicator has
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

West Hackney questions
Do you work for landlords with property near Rectory Road station?

Is parking an issue for new build mastic in West Hackney?
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.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Can you do plot mastic on a new development?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.

- The number and length of the joints
- Mould in or behind the old joints

- The address or postcode of the job
- How we’d reach the joints
- The type of property
- How many joints, rooms or windows are involved

Joints and finishes in West Hackney homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
West Hackney is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
