New build mastic for homes and businesses in Street End
We work in new homes and on new-build sites across Street End. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on bathrooms & en suites, kitchens and skirting & floors, and people most often call us about skirting joints opening in the first winter and untidy sealant flagged on a snagging list.
Around Street End, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Common problems we fix in Street End
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The problems people usually mention when they call include:
- Second-fix sealing on new plots
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
If you’ve bought a new home near Canterbury East station, the sealant around baths, showers and frames is worth checking in the first year or two.

- Whether all the old sealant comes out first
- What product goes in the joint
Why deal with it now?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Older cottages and farmhouses around Street End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- A choice of colours where the product allows
- We are fully insured
- Sealant colour chosen to suit
- Old sealant always removed completely

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
- Do not wait for the house to settle if water is getting through
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.
Which products 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.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours in a single home. We will tell you when we quote.
Should I go to my builder first?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Different surfaces, different methods
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
