DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
New build mastic in Matching
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on kitchens, skirting & floors and show homes, and common reasons people get in touch are cracked caulk along new skirting and cracked sealant around new window and door frames.
In a village or hamlet like Matching, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Each job carries a 12-month guarantee, whatever its size.

What the job involves on each surface
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Common reasons people contact us are:
- Cracks appearing as a new home settles
- Skirting joints opening in the first winter
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
For new homes near Sawbridgeworth station, it’s worth checking the sealant early, while snags are still fresh.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. In a small place like Matching, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- 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.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Keeping the joints in good condition
Looking after new joints is easy:
- Do not wait for the house to settle if water is getting through
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Record problems with dated pictures
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
