How we handle new build mastic in Widley
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. Typical jobs include beads laid onto grit and dust from the build and sealant work across a run of new homes, on kitchens, show homes and plot handovers.
For a small place like Widley, the journey and access are planned in advance, and the work itself is the same as on any site.
Every job is covered by a one-year guarantee.

Widley: your questions answered
Do you cover smaller places like Widley?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Widley in your area for new build mastic?
Yes, Widley is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Are you insured?
Yes. Full insurance covers our work.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
My new home is still under warranty. Should I contact you?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.

Do you need new build mastic in Widley?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Most people get in touch after spotting something like this:
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- Internal frame sealant that has split
- Leaking shower tray seals in a new home
For new homes near Cosham station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- How the surfaces are prepared before sealing
- What the cure time is
- Is the old sealant removed completely?
- Whether the sealant suits the joint
How it works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours in a single home in most cases. Somewhere as small as Widley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Keep pictures and emails about snagging items
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

How the job changes by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
New homes and floors in Widley
Widley is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Widley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Honest limits
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Movement caused by a poorly fitted tray or bath
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
