Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
New build mastic in Jack's Hatch
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on show homes, kitchens and windows & doors, and the jobs we see most are gaps between new skirting and floors and new-build shower sealant that has already split.
Somewhere as small as Jack's Hatch, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes as standard.

FAQs for Jack's Hatch
Do you cover smaller places like Jack's Hatch?

Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
Why does sealant fail so quickly in new builds?
There are normally two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.

Leave it or put it right?

Around Jack's Hatch, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

How the job changes by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. We’ll plan around viewing times.
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and primer used where needed.
Landlord and commercial work in Jack's Hatch
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
What sealant work cannot fix
Before you book, it’s worth knowing the limits:
- A tray or bath that is not properly supported, until it’s fixed
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
