How we handle new build mastic in Chingford Hatch
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant usually lacks. We work on plot handovers, kitchens and windows & doors, and common reasons people get in touch are skirting joints opening in the first winter and cracked sealant around new window and door frames.
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.
Big or small, you get the same one-year guarantee in Chingford Hatch and across Greater London.

Why it’s worth doing now in Chingford Hatch
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. 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 Chingford Hatch, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

What else we do in Chingford Hatch
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Questions from Chingford Hatch
Can you help a landlord with a rental near Highams Park station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can you do new build mastic in Chingford Hatch?
Yes. We work across London and the South East, and Chingford Hatch is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Can I add another job to the visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we will do.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
What we do, step by step
The work is kept neat and contained to the joints we’re treating. The job usually takes anything from a few hours to several days, depending on the number of plots.

- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any leaks or damp you’ve noticed

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Small gaps can appear as the house dries.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
