New build mastic in Holly Green, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, show homes and kitchens, and people most often call us about internal frame sealant that has split and smeared, uneven beads picked up at snagging.
Somewhere as small as Holly Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
You get a one-year guarantee, the same in Holly Green as everywhere else we work.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
