- Gaps between new skirting and floors
- Internal frame sealant that has split
- Sealant that never bonded to the surface
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
- Wait for the cure time before using a resealed shower
- Keep photos and emails about snagging items
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
New build mastic in Platt's Heath
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Typical jobs include gaps opening as the house dries out and settles and kitchen sealant that has pulled off the wall, on skirting & floors, bathrooms & en suites and kitchens.
Older homes in small places like Platt's Heath often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months.

- Where the job is, and your postcode
- Any previous sealing or DIY work

Common questions in Platt's Heath
Can you help a landlord with a rental near Lenham station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Platt's Heath within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.
Do you have insurance?
Yes. Full insurance covers our work.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
How long will you be here?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. We’ll confirm how long when we quote.
Common problems we fix in Platt's Heath
Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry first.
Look out for these signs:
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
- Sealant that never bonded to the surface
In and around Platt's Heath, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Landlords, agents and businesses in Platt's Heath
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What we do, step by step
At the end, we look at the finished work together. The work normally takes a few hours in a single home, depending on the amount of work.
