FAQs for Newenden
Is there a guarantee on new build mastic in Newenden?
All our work, in Newenden and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Newenden within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Do you use white or clear sealant?
White and clear are the most common, but other colours are available. We match the colour to the finish.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
New build mastic in Newenden, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. If you are dealing with joints pulling apart as timber shrinks and sealant applied over dusty or wet surfaces, we can help, whatever the surface.
Work in a small place like Newenden just needs the journey and access planning, and the work itself is the same as on any site.
Big or small, it’s backed by our 12-month guarantee.

When to call us in Newenden
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 first.
Look out for these signs:
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
- Smeared, uneven beads picked up at snagging
Whether the job is in Newenden itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- How the colour is chosen
- Whether they’re fully insured
- When the joint can take water or movement
- Which sealant they’ll use, and why
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.

DIY sealant or a professional job?
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.
What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours for most snagging lists, longer for a run of plots from start to finish. In a small place like Newenden, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Around Newenden, 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: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why Newenden clients choose us
