Do you need new build mastic in Woodcock Hill?
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Look out for these signs:
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
In and around Woodcock Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Whether VAT is included
- Which sealant they’ll use, and why
- How hidden problems are handled
- The length of the guarantee

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Keep pictures and emails about snagging items
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In a small place like Woodcock Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What you get with us
- Colour picked to suit the job
- More than 20 years in sealant work
- We agree the colour with you first
- Quality sealants from Arbo and Everbuild

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. In a small place like Woodcock Hill, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
