New build mastic in Magdalen Laver, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We work on show homes, skirting & floors and windows & doors, and the jobs we see most are internal frame sealant that has split and skirting joints opening in the first winter.
Older homes in small places like Magdalen Laver often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, large or small.

For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
- Get a leaking seal dealt with right away
- Report sealant problems to your builder during the snagging period
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
Signs you need new build mastic in Magdalen Laver
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Any of these means the joints need attention:
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
If you’ve bought a new home near Harlow Mill station, the sealant around baths, showers and frames is worth checking in the first year or two.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
