New Build Mastic in Walhampton
New-build sealant joints in Walhampton need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
How we handle new build mastic in Walhampton
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, skirting & floors and kitchens, and people most often call us about shower seals failing in the first year or two and internal frame sealant that has split.
For a small place like Walhampton, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, you get the same 12-month guarantee in Walhampton and across Hampshire.

Walhampton questions
Do you cover smaller places like Walhampton?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Lymington Town station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it normal for sealant to crack in a new home?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
Why act early in Walhampton
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. Where a wall is exposed, as many are in small places like Walhampton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

- 12-month guarantee on every job

What we do, step by step
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. In total, it generally takes a few hours for most snagging lists, longer for a run of plots. In a small place like Walhampton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

New homes and floors in Walhampton
Walhampton is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Lymington Town station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Open a window or run the fan after bathing
- Get a leaking seal dealt with straight away
- Put sealant faults on your snagging list early
- Do not seal over failed sealant yourself
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
Common problems we fix in Walhampton
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Common reasons people contact us include:
- Gaps behind new kitchen upstands
- Frame joints opening as the plaster dries
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
Around Walhampton, as everywhere, new build mastic is only as good as the preparation behind it.
