How we handle new build mastic in Marks Gate
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 bathrooms & en suites, plot handovers and windows & doors, and common reasons people get in touch are messy sealant that spoils new finishes and gaps opening as the house dries out and settles.
For a small place like Marks Gate, the journey and access are planned in advance, and the work itself is the same as on any site.
Whatever the size of the job, you get the same 12-month guarantee.

Aftercare tips
Looking after new joints is easy:
- Wait for the cure time before using a resealed shower
- Photograph failed sealant before it’s redone
- Don’t seal over failed sealant yourself
- Don’t wait for the house to settle if water is getting through
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Should I try it myself first?
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. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
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. In a small place like Marks Gate, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Tell us if parking is tricky

Advice
Different surfaces, different methods
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.
Do you need new build mastic in Marks Gate?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Signs it’s time to call us include:
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
- Cracks appearing as a new home settles
If you’ve bought a new home near Chadwell Heath station, the sealant around baths, showers and frames is worth checking in the first year or two.
