New build mastic in Walter's Green, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on plot handovers, show homes and skirting & floors, and common reasons people get in touch are frame joints opening as the plaster dries and cracked caulk along new skirting.
Around Walter's Green, 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.
Big or small, you get the same 12-month guarantee.

Walter's Green questions
Can you help a landlord with a rental near Ashurst Kent station?
Yes. We work for landlords and agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Walter's Green?
Yes. Walter's Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you insured?
Yes. Full insurance covers our work.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, large or small.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items. We will tell you if anything on it isn’t a sealant job.
Where do you work from?
We work from Crawley. We cover Walter's Green and the rest of Kent.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
How it works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. In a small place like Walter's Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before any work starts.
- We remove the failed sealant and clean the joints.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Why it’s worth doing now in Walter's Green
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Older cottages and farmhouses around Walter's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Use the extractor fan every time you shower
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
Common problems we fix in Walter's Green
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops.
It’s worth asking for a quote if you see:
- Plot mastic for developers ahead of handover
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
In and around Walter's Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- What insurance they hold
- Which colour the sealant will be
- What the cure time is
- Who does the work, and how experienced they are
DIY versus a professional finish
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
