Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
How we handle new build mastic in Horney Common
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with sealant that never bonded to the surface and sealant work across a run of new homes, on kitchens, bathrooms & en suites and windows & doors.
In a village or hamlet like Horney Common, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Related advice
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Around Horney Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Wipe joints with warm soapy water
- Don’t wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
How the job changes by surface
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out.
Honest limits
In fairness, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
