New Build Mastic in Wildmoor
Professional new build mastic in and around Wildmoor, with old sealant always removed completely and a one-year guarantee.
- Gaps behind new kitchen upstands
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
New build mastic in Wildmoor, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with frame joints opening as the plaster dries and cracks appearing as a new home settles, across bathrooms & en suites, skirting & floors and plot handovers.
Somewhere as small as Wildmoor, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. In a small place like Wildmoor, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Common problems we fix in Wildmoor
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Most people get in touch when they notice one of these:
- Frame joints opening as the plaster dries
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Bramley (Hants) station, the sealant around baths, showers and frames is worth checking in the first year or two.

What new build mastic looks like in Wildmoor
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Wipe joints with warm soapy water
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you so report it promptly.
What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Wildmoor questions
I let a flat near Bramley (Hants) station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is Wildmoor in your area for new build mastic?
Yes. We work across London and the South East, and Wildmoor is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Can I send you my snagging list?
Yes. Send it with photos and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.
Are you insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Wildmoor can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
