How the job changes by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

When to call us in Charvil
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Any of these means the joints need attention:
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
- Worktop and upstand sealant coming away
- Sealant work across a run of new homes
In and around Charvil, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
Looking after new joints is easy:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day to cure enough for use.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
Questions from Charvil
Do you work for landlords with property near Twyford station?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do new build mastic in Charvil?
Yes, Charvil is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.
Why act early in Charvil
A hairline gap at a skirting can wait, but water getting through cannot. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few photos and we will give you a straight answer. Homes in smaller places like Charvil can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.

Before we arrive
- Tell us about any water getting in
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
