New Build Mastic in Hackney
Problem with your new-build sealant joints in Hackney? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
- Messy sealant that spoils new finishes
How we handle new build mastic in Hackney
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have leaking shower tray seals in a new home and smeared, uneven beads picked up at snagging, we can put it right, whatever the surface.
New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Whatever the size of the job, it’s backed by our one-year guarantee.

What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through cannot. If you are unsure which you have, ring 0345 464 0079 or drop us an email with photos. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Hackney, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
What you get with us
- Sealant colour chosen to suit
- Tidy, careful work
- 12-month guarantee on every job
- Anti-fungal silicone where joints get wet

What we are called out for in Hackney
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
It’s worth asking for a quote if you see:
- Smeared, uneven beads picked up at snagging
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
If you’ve bought a new home near Homerton station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Who turns up on the day
- Is VAT in the price?
- How the surfaces are prepared before sealing
- When the joint can take water or movement
What affects the quote in Hackney
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- The product the joint needs
- The number of rooms or windows
- The number and length of the joints
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What we need to know
When you contact us, it’s useful to know:
- Roughly how big the job is
- Any previous sealing or DIY work
- Where the property is
- If it’s domestic, commercial or a hotel
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Damaged fittings that need replacing
- Structural cracks in walls or ceilings
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly.

Landlords, agents and businesses in Hackney
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents 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.
- We check every joint and leave you with the cure times.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts

Advice
DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What new build mastic looks like in Hackney
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.

Common questions in Hackney
Can parking be tricky for a visit in Hackney?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you do new build mastic in Hackney?
Yes. We work across London and the South East, and Hackney is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Is there a guarantee?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
