New-build mastic & snagging in Hungerford, Hampshire
New build mastic for Hungerford and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
New build mastic in Hungerford, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. If you’re dealing with skirting joints opening in the first winter and worktop and upstand sealant coming away, we can put it right, on windows & doors, bathrooms & en suites and plot handovers alike.
For a small place like Hungerford, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What happens if it’s left?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Hungerford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Common problems we fix in Hungerford
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
If you can see any of these, it’s time to have the joints looked at:
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
Around Hungerford, as everywhere, new build mastic is only as good as the preparation behind it.

FAQs for Hungerford
Is new build mastic in Hungerford guaranteed?
All our work, in Hungerford and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover Hungerford for new build mastic?
Yes. We work across London and the South East, and Hungerford is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Will you leave a mess?

Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours in a single home. In a small place like Hungerford, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
How to get a quote

Keeping the joints in good condition
So the new joints stay in good condition:
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What new build mastic looks like in Hungerford
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Whether the job is in Hungerford itself or nearby, the right material for each joint matters as much as a neat finish.
