New build mastic in Eastergate
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait.

Leave it or put it right?
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. Around Eastergate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

What we are called out for in Eastergate
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
Common reasons people contact us include:
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
- Frame joints opening as the plaster dries
- Leaking shower tray seals in a new home
In and around Eastergate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- What the cure time is
- What insurance they hold
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracking that points to a structural problem
- A tray or bath that is not properly supported, until it’s fixed
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
Surfaces we seal

- Bathrooms & en suites

How the job changes by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
