New build mastic in Bitterne, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with shower seals failing in the first year or two and cracked sealant around new window and door frames, across bathrooms & en suites, kitchens and plot handovers.
If you’ve bought a new home in or near Bitterne, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What else we do in Bitterne
What we are called out for in Bitterne
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Most people get in touch after spotting one of these:
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near Bitterne station, the sealant around baths, showers and frames is worth checking in the first year or two.

Bitterne questions
Is Bitterne within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Bitterne station. Can you help?
Yes, rental work is part of what we do. 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 work begins.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Should I wait before resealing?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
How long does the job take?
As a guide, most jobs take a few hours in a single home. Bigger jobs take longer, and we’ll say how long yours will take.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Do you guarantee your work?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
How the job changes by surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
The process
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. Parking around Bitterne is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
