New-build mastic & snagging in Teynham, Kent
New-build sealant joints in Teynham need attention? We remove the old material, prepare the joints and seal them properly.
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Messy sealant that spoils new finishes
About our new build mastic in Teynham
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant usually lacks. We work on skirting & floors, bathrooms & en suites and plot handovers, and people most often call us about messy sealant that spoils new finishes and frame joints opening as the plaster dries.
Where new homes go up in smaller places like Teynham, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. A visit to Teynham is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
- Tell us about any water getting in

Different surfaces, different methods
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Work for landlords, hotels and businesses
If you manage several properties in or around Teynham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we cannot put right
It helps to know what we cannot do too:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- Broken tiles or a split tray
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Why act early in Teynham
DIY kits don’t 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. In an older home around Teynham, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Questions from Teynham
Is Teynham within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Teynham station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How long will you be here?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Larger jobs naturally take longer, and we’ll say how long yours will take.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where are you based?
Mr Mastic is based in Crawley. We cover Teynham and the rest of Kent.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
