How we handle new build mastic in Mill End
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for cracked sealant around new window and door frames and gaps opening as the house dries out and settles, on bathrooms & en suites, show homes and plot handovers.
For a small place like Mill End, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.

Mill End questions
Can you do new build mastic in Mill End?
Yes. We work across London and the South East, and Mill End is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear quote.
Is Mill End within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
When to call us in Mill End
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- Gaps between new skirting and floors
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
In and around Mill End, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- Whether all the old sealant comes out first
- What product goes in the joint
- What happens if the job turns out different
- How the colour is chosen
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Broken tiles or a split tray
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Windows & doors
- Plot handovers
- Show homes
- Bathrooms & en suites
- Skirting & floors
- Kitchens
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Different surfaces, different methods
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
