About our new build mastic in Charleshill
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on kitchens, windows & doors and plot handovers, and people most often call us about messy sealant that spoils new finishes and joints pulling apart as timber shrinks.
Older homes in small places like Charleshill often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job is covered by a one-year guarantee, wherever you are in Surrey.

How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Charleshill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before work begins.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Where is Mr Mastic based?

Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on
- Plot handovers
- Bathrooms & en suites
- Kitchens
- Windows & doors
- Show homes
- Skirting & floors
What the job involves on each surface
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered to the agreed spec.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Resist patching a failed seal with a tube from the DIY shop
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Wipe joints with warm soapy water
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
