Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How the visit works
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Brockhill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on

Aftercare tips
Looking after new joints is easy:
- Photograph failed sealant before it’s redone
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Raise failed sealant with the developer while you are covered
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you, so raise it early.

Signs you need new build mastic in Brockhill

The problems people normally mention when they call are:
- Beads laid onto grit and dust from the build
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
For new homes near Martins Heron station, it’s worth checking the sealant early, while snags are still fresh.

Surface by surface
Windows and doors
