- Cracked sealant around new window and door frames
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Look at the sealant regularly in the first couple of years
- Keep water off fresh sealant until it has cured
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
New build mastic for homes and businesses in Rudmore
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Common call-outs are for untidy sealant flagged on a snagging list and sealant work across a run of new homes, on show homes, bathrooms & en suites and windows & doors.
Where new homes go up in smaller places like Rudmore, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Can you do new build mastic in Rudmore?
Yes, Rudmore is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Can you help a landlord with a rental near Portsmouth & Southsea station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we will quote. We’ll flag anything that needs another trade.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
New build mastic in Rudmore: local notes
Rudmore is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Rudmore, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. In an older home around Rudmore, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

When to call us in Rudmore
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Most people get in touch after spotting one of these:
- Joints pulling apart as timber shrinks
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
- Sealant that never bonded to the surface
If you’ve bought a new home near Portsmouth & Southsea station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Who does the work, and how experienced they are
- How long to leave it before use
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- Working hours on commercial sites
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
Helping us quote
To make quoting easier, please include:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking

What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. For a job in Rudmore, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, 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.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Mention any tricky access

What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
