About our new build mastic in Great Leighs
Across Great Leighs, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on skirting & floors, windows & doors and bathrooms & en suites, and the jobs we see most are frame joints opening as the plaster dries and worktop and upstand sealant coming away.
Around Great Leighs, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens if it’s left?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. In a small place like Great Leighs, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
- Damaged fittings that need replacing
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Windows & doors
- Kitchens
- Skirting & floors
- Bathrooms & en suites
- Plot handovers
- Show homes
Do you need new build mastic in Great Leighs?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
The most common problems we see are:
- New-build shower sealant that has already split
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
If you’ve bought a new home near Cressing station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before you book anyone
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
- What product goes in the joint
- Whether you can choose the colour
DIY versus a professional 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Aftercare tips
Aftercare is simple:
- Raise failed sealant with the developer while you’re covered
- Watch for new gaps as the house dries out
- Do not seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers to help keep mould away.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small.
How we quote for new build mastic
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
When you call or email, these details help:
- Where the property is
- If someone has resealed it before
- Whether it’s a home or a business
- Any access issues, like height or stairs
