About our new build mastic in Woodside
We work in new homes and on new-build sites across Woodside. 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 bathrooms & en suites, plot handovers and windows & doors, and the jobs we see most are gaps between new skirting and floors and shower seals failing in the first year or two.
Older homes in small places like Woodside often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, it’s backed by our 12-month guarantee in Woodside and across Hampshire.

Questions from Woodside
Do you cover Woodside for new build mastic?
Yes, Woodside is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you cover smaller places like Woodside?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer, and we’ll tell you how long to expect.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
Are you fully insured?
Yes. We’re fully insured.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Joints and finishes in Woodside homes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Whether the job is in Woodside itself or nearby, the right material for each joint matters as much as a neat finish.

When to call us in Woodside
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Most people get in touch when they notice one of these:
- Beads laid onto grit and dust from the build
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
- Cracked caulk along new skirting
Around Woodside, as everywhere, new build mastic is only as good as the preparation behind it.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Do not seal over failed sealant yourself
- Ventilate bathrooms well, especially in the first year
- Raise failed sealant with the developer while you’re covered
- Record problems with dated pictures
Watch the joints as the house settles. Small gaps can appear as the house dries.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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.

What affects the cost of new build mastic

What we need to know
When you call or email, these details help:
- How we’d reach the joints
- Where the job is, and your postcode

What happens if it’s left?
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. Older cottages and farmhouses around Woodside can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. In a small place like Woodside, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Keep children and pets away from the work area
