New build mastic in Charlwood, done properly
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, bathrooms & en suites and plot handovers, and the jobs we see most are beads laid onto grit and dust from the build and untidy sealant flagged on a snagging list.
In a village or hamlet like Charlwood, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee.

When to call us in Charlwood
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Common reasons people contact us are:
- Skirting joints opening in the first winter
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
If you’ve bought a new home near Ifield station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Whether the sealant suits the joint
- Whether you can choose the colour
- How much experience the applicator has
- What the cure time is
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a village or hamlet like Charlwood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on

- Access and height
- How much old sealant there is and how hard it is to remove

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Your questions about new build mastic in Charlwood
Do you cover Charlwood for new build mastic?
Yes, Charlwood is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Ifield station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Charlwood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
