New build mastic in Piccotts End
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. Common call-outs are for shower seals failing in the first year or two and sealant work across a run of new homes, across show homes, plot handovers and skirting & floors.
Older homes in small places like Piccotts End often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job comes with a 12-month guarantee, wherever you are in Hertfordshire.

What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Deciding who is responsible under a builder’s warranty
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Show homes
- Bathrooms & en suites
- Plot handovers
- Skirting & floors
- Kitchens
- Windows & doors
What happens if it’s left?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. Older cottages and farmhouses around Piccotts End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Landlord and commercial work in Piccotts End
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
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.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with right away
- Wait for the cure time before using a resealed shower
- Raise failed sealant with the developer while you are covered
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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 doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What we are called out for in Piccotts End
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
People generally contact us after spotting one of these:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
If you’ve bought a new home near Hemel Hempstead 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
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
- How much experience the applicator has
