Why deal with it now?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Where a wall is exposed, as many are in small places like Wallcrouch, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What you get with us
- ARBOMaster approved applicator
- A sealant colour to suit the surroundings
- Neat joints and a tidy finish
- Sanitary silicone with an anti-fungal additive in wet areas

New build mastic in Wallcrouch, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on windows & doors, kitchens and show homes, and the jobs we see most are gaps between new skirting and floors and new-build shower sealant that has already split.
For a small place like Wallcrouch, the journey and access are planned in advance, and the work itself is the same as on any site.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What affects the quote in Wallcrouch
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- How many areas need sealing
- Mould in or behind the old joints
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
- Whether it’s a home or a business
- Where the job is, and your postcode
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work and give you a clear price.
How to look after the new joints
Looking after new joints is easy:
- Record problems with dated pictures
- Check bath and shower seals every few months as the house settles
- Follow the cure time we give you
- Raise failed sealant with the developer while you’re covered
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
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
A careful DIYer can reseal a simple joint, 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, then guaranteed for a year.
Signs you need new build mastic in Wallcrouch
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
Most people get in touch when they notice something like this:
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
- Gaps between new skirting and floors
- Joints pulling apart as timber shrinks
Around Wallcrouch, as everywhere, new build mastic is only as good as the preparation behind it.
