New build mastic in South Leigh
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. Typical jobs include kitchen sealant that has pulled off the wall and untidy sealant flagged on a snagging list, on show homes, bathrooms & en suites and skirting & floors.
Around South Leigh, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- Working hours on commercial sites
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Can I add another job to the visit?

Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How long will you be here?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home. Somewhere as small as South Leigh, access is often the only tricky part. 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.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive

Aftercare tips
To keep the joints looking good and working properly:
- Get a leaking seal dealt with right away
- Report sealant problems to your builder during the snagging period
- Use the extractor fan every time you shower
- Look at the sealant regularly in the first couple of years
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Why act early in South Leigh
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Around South Leigh, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
