How we handle new build mastic in Finchingfield
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. If you have sealant that never bonded to the surface and messy sealant that spoils new finishes, we can put it right, whatever the surface.
Somewhere as small as Finchingfield, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A one-year guarantee comes as standard.

What the job involves on each surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
Plot handovers
Send us the schedule and any sealant specification and we will quote. Sealant work across the plot is covered to the agreed spec.
Do you need new build mastic in Finchingfield?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
It’s worth asking for a quote if you see:
- Plot mastic for developers ahead of handover
- Gaps between new skirting and floors
- Sealant applied over dusty or wet surfaces
- Shower seals failing in the first year or two
In and around Finchingfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Whether all the old sealant comes out first
- What happens if the job turns out different
- Which sealant they’ll use, and why
- The length of the guarantee
What affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- The amount of work
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Where the property is
- A few pictures by email, if you can
We quote each job on its own, so start by telling us what you need. Just call 0345 464 0079 or email us with the details, and pictures are welcome.
Why deal with it now?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around Finchingfield can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
Why us?
- 20+ years of sealant experience
- A choice of colours where the product allows
- You choose the colour before work begins
- One-year guarantee on every job

Your questions about new build mastic in Finchingfield
Is Finchingfield within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Finchingfield in your area for new build mastic?
Yes. We work across London and the South East, and Finchingfield is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How long will you be here?
Most jobs take a few hours in a single home, including the preparation. We will confirm how long when we quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we will quote.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.

What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

Should I try it myself first?
If you do try it yourself, take your time over the 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.
A careful DIYer can reseal a simple joint, 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.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home and we leave things clean and tidy. In a small place like Finchingfield, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Move anything stored near the joints
