DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
New build mastic in Hackney Central, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We are often asked to deal with cracks appearing as a new home settles and cracked caulk along new skirting, on windows & doors, skirting & floors and show homes.
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, in Hackney Central as anywhere.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. If you are unsure which you have, phone 0345 464 0079 or send us an email with photos. In a flat in Hackney Central, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why book with us
- Over 20 years’ experience
- An ARBOMaster approved applicator
- Old sealant always removed completely

Hackney Central: your questions answered
Can you help a landlord with a rental near London Fields station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Can parking be tricky for a visit in Hackney Central?
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 plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
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.
Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. If it isn’t resolved, we will cut it out and reseal it.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
- Cracking that points to a structural problem
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

When to call us in Hackney Central
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Most people get in touch after spotting something like this:
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
If you’ve bought a new home near London Fields station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- How hidden problems are handled
- Which colour the sealant will be
