How we handle new build mastic in The Holt
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. Common call-outs are for untidy sealant flagged on a snagging list and cracks appearing as a new home settles, on kitchens, bathrooms & en suites and show homes.
Around The Holt, 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why it’s worth doing now in The Holt
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. Older cottages and farmhouses around The Holt can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Aftercare tips
To keep the joints looking good and working properly:
- Ventilate bathrooms well, especially in the first year
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
Follow the cure time we give you before the area gets wet. Silicone is normally left for about a day to cure enough for use.
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.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Disputes or warranty claims with your builder
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

How it works
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. In a small place like The Holt, 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.
- The failed sealant is removed completely, with no layer left behind.
- 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.
- Each bead is tooled and the cure times explained.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you need new build mastic in The Holt?
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The problems people usually mention when they call include:
- Leaking shower tray seals in a new home
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
For new homes near Wargrave station, it’s worth checking the sealant early, while snags are still fresh.
