New-build mastic & snagging in Hursley, Hampshire
Professional new build mastic in and around Hursley, with every bit of old sealant taken out first and a 12-month guarantee.
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
How we handle new build mastic in Hursley
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference. We work on plot handovers, kitchens and skirting & floors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and frame joints opening as the plaster dries.
Somewhere as small as Hursley, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes as standard.

What we’re called out for in Hursley
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.
The most common problems we see are:
- Joints pulling apart as timber shrinks
- Smeared, uneven beads picked up at snagging
- Second-fix sealing on new plots
- Shower seals failing in the first year or two
If you’ve bought a new home near Shawford station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Are they insured?
- Whether VAT is included
- Which colour the sealant will be
- Who turns up on the day
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Report sealant problems to your builder during the snagging period
- Clean sealant with mild detergent, not abrasives
- Do not seal over failed sealant yourself
- Use the extractor fan every time you shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
How the job changes by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
What happens on the day
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere like Hursley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area
- Mention any tricky access

Hursley questions
Is Hursley in your area for new build mastic?
Yes, Hursley is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is Hursley within the area you cover?
Yes. Hursley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Do you work through snagging lists?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before work begins.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
What colour sealant will you use?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
