New build mastic for homes and businesses in Starling's Green
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on show homes, windows & doors and skirting & floors, and common reasons people get in touch are gaps opening as the house dries out and settles and internal frame sealant that has split.
Around Starling's Green, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
All our work comes with our one-year guarantee, wherever you are in Essex.

How we quote for new build mastic
You’ll get a clear quote before any work starts. It’s based on:
- Mould in or behind the old joints

- Any working-time requirements on site
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
What to tell us for a quote
To make quoting easier, please include:
- The address or postcode of the job
- Access, such as stairs, a lift or height
- If someone has resealed it before
- Photos by email, if that’s easy

How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Starling's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

Signs you need new build mastic in Starling's Green
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
These are the problems we are asked about most:
- Gaps behind new kitchen upstands
- Frame joints opening as the plaster dries
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
If you’ve bought a new home near Newport (Essex) station, the sealant around baths, showers and frames is worth checking in the first year or two.

What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- Broken tiles or a split tray
- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
How long does the job take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including preparation and clearing up. We will confirm how long when we quote.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How the job changes by surface
