Joints and finishes in Adeyfield homes
Hemel Hempstead, which Adeyfield is part of, is one of England’s post-war new towns. Hemel Hempstead has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Newer homes need snagging; older ones need their joints renewing. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Apsley station, the sealant around baths, showers and frames is worth checking in the first year or two.

About our new build mastic in Adeyfield
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant normally lacks. We are often asked to deal with plot mastic for developers ahead of handover and leaking shower tray seals in a new home, on skirting & floors, plot handovers and windows & doors.
If you’ve bought a new home in or near Adeyfield, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Your job is guaranteed for a year, as with all our work.

What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.

What else we do in Adeyfield
Landlord and commercial work in Adeyfield
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
DIY versus a professional finish
If you’re set on DIY, put the effort into 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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours in a single home, and the area is left clean. A visit to Adeyfield is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Tell us if parking is tricky
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Common problems we fix in Adeyfield
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry.
People generally contact us when they notice something like this:
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Internal frame sealant that has split
In and around Adeyfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
