About our new build mastic in Spitalfields
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. If you have plot mastic for developers ahead of handover and cracked sealant around new window and door frames, we can help, whatever the surface.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.
All our work comes with our one-year guarantee.

FAQs for Spitalfields
I let a flat near London Liverpool Street station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is parking a problem for a job in Spitalfields?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you cover Spitalfields?
Yes. We work in Spitalfields and the rest of Greater London, as part of our work across South East England, London and Scotland. For a quote, phone 0345 464 0079 or send us an email.
Who should fix failed sealant in a new build?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you.

Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.

Common problems we fix in Spitalfields

These are the problems we are asked about most:
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
As a London address, Spitalfields can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

How we quote for new build mastic
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- The type of sealant required
- Working hours on commercial sites
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
When you contact us, it’s useful to know:
- How we’d reach the joints
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What new build mastic looks like in Spitalfields
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near London Liverpool Street station, it’s worth checking the sealant early, while snags are still fresh.
