New build mastic in Butler's Cross, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant usually lacks. Common call-outs are for untidy sealant flagged on a snagging list and frame joints opening as the plaster dries, across show homes, bathrooms & en suites and plot handovers.
Around Butler's Cross, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Every job comes with our one-year guarantee, wherever you are in Buckinghamshire.

Do you need new build mastic in Butler's Cross?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Keep an eye out for these signs:
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
Around Butler's Cross, as everywhere, new build mastic is only as good as the preparation behind it.

Questions from Butler's Cross
Do you work for landlords with property near Little Kimble station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Butler's Cross?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What does new build mastic cost?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What colour sealant will you use?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We’ll agree it with you first.
Why act early in Butler's Cross
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. Around Butler's Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why choose Mr Mastic in Butler's Cross

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.

Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will come back to you with a quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Wait for the cure time before using a resealed shower
- Photograph failed sealant before it’s redone

- Resist patching a failed seal with a tube from the DIY shop
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
