New build mastic in Petersfield
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. If you have shower seals failing in the first year or two and plot mastic for developers ahead of handover, we can put it right, on bathrooms & en suites, skirting & floors and kitchens alike.
Small business units and shops in a town like Petersfield have floors that take heavy wear. Joints at thresholds and in tiled or concrete floors need resealing before the edges start to break up.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Can I do it myself?
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. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours in a single home. A visit in Petersfield needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Do you need new build mastic in Petersfield?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Signs it’s time to call us include:
- New-build shower sealant that has already split
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Petersfield station, the sealant around baths, showers and frames is worth checking in the first year or two.

Is there a guarantee on new build mastic in Petersfield?

Are you fully insured?
Yes, we’re fully insured.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Who should fix failed sealant in a new build?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Structural cracks in walls or ceilings
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaking fittings rather than failed sealant
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Clean sealant with mild detergent, not abrasives
- Do not wait for the house to settle if water is getting through
- Raise failed sealant with the developer while you’re covered
- Look at the sealant regularly in the first couple of years
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
