New build mastic in Netherfield, 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 since hurried prep is behind a lot of new-build failures. We work on bathrooms & en suites, show homes and skirting & floors, and common reasons people get in touch are messy sealant that spoils new finishes and gaps between new skirting and floors.
Work in a small place like Netherfield just needs the journey and access planning, and once on site, the job is the same as anywhere.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

When to call us in Netherfield
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
It’s worth asking for a quote if you see:
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
Around Netherfield, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- When the joint can take water or movement
- Whether they seal over old material or remove it
- Which colour the sealant will be
- What happens if they find a problem under the old sealant

What else we do in Netherfield
How it works
We keep the work tidy and contained to the area we are working on. The job normally takes a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. In a small place like Netherfield, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children

Advice
Should I try it myself first?
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 cut it out and start again.

Why it’s worth doing now in Netherfield
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Netherfield, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
