Can I do it myself?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
New build mastic in Painters Ash, done properly
We work in new homes and on new-build sites across Painters Ash. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on bathrooms & en suites, windows & doors and plot handovers, and common reasons people get in touch are cracked sealant around new window and door frames and skirting joints opening in the first winter.
For a new home in or near Painters Ash, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You get a one-year guarantee, the same in Painters Ash as everywhere else we work.

The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours in a single home. Parking around Painters Ash is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

What we are called out for in Painters Ash
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
Look out for any of the following:
- Frame joints opening as the plaster dries
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
- Gaps opening as the house dries out and settles
For new homes near Ebbsfleet International station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- What happens if the job turns out different
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
- Which colour the sealant will be
Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Record problems with dated pictures
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left in a busy bathroom.
Why act early in Painters Ash
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In an older home around Painters Ash, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
