Tunbridge Hill questions
Is Tunbridge Hill in your area for new build mastic?
Yes, Tunbridge Hill is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Gillingham (Kent) station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
New build mastic for homes and businesses in Tunbridge Hill
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. Typical jobs include sealant that never bonded to the surface and joints pulling apart as timber shrinks, on show homes, plot handovers and skirting & floors.
Around Tunbridge Hill, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job.

How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a village or hamlet like Tunbridge Hill, the journey is planned in advance: 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

New homes and floors in Tunbridge Hill
Tunbridge Hill is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Gillingham (Kent) station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Tunbridge Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in Tunbridge Hill
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Tunbridge Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Clean sealant with mild detergent, not abrasives
- Keep pictures and emails about snagging items
- Avoid running a DIY bead over the old one
- Open a window or run the fan after bathing
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
When it is not the sealant
A few problems are outside what sealant work can do:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
