New Build Mastic in Northchapel
Plot mastic for developers and snagging failed sealant in new homes for householders, landlords and businesses in Northchapel. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Watch for new gaps as the house dries out
- Clean sealant with mild detergent, not abrasives
- Photograph failed sealant before it’s redone
- Do not wait for the house to settle if water is getting through
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
New build mastic for homes and businesses in Northchapel
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on skirting & floors, plot handovers and windows & doors, and the jobs we see most are second-fix sealing on new plots and untidy sealant flagged on a snagging list.
Around Northchapel, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months.

How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Northchapel needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

The most common problems we see are:
- Cracks appearing as a new home settles
- Sealant work across a run of new homes
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
If you’ve bought a new home near Haslemere station, the sealant around baths, showers and frames is worth checking in the first year or two.

What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.
When something else is needed
In fairness, some problems need a different trade:
- Damaged fittings that need replacing
- Plumbing faults behind the sealant
- Settlement cracks that need a surveyor
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
What we seal
- Skirting & floors
- Windows & doors
- Kitchens
- Bathrooms & en suites

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
