About our new build mastic in Horseman Side
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. Common call-outs are for cracked sealant around new window and door frames and gaps behind new kitchen upstands, across bathrooms & en suites, kitchens and skirting & floors.
For a small place like Horseman Side, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
You get a 12-month guarantee, the same in Horseman Side as everywhere else we work.

Common questions in Horseman Side
Do you work for landlords with property near Brentwood station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.

My new home is still under warranty. Should I contact you?
Start with the builder if you’re in the snagging or warranty period. If it is not resolved, we can reseal it properly.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Most jobs take anything from a few hours to several days, depending on the number of plots, including the preparation. We will confirm how long when we quote.
Do you take on second-fix sealing for builders?

What sealant work can’t fix

What else we do in Horseman Side
What we’re called out for in Horseman Side
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
These are the problems we are asked about most:
- Sealant that never bonded to the surface
- Frame joints opening as the plaster dries
- Cracked caulk along new skirting
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Brentwood station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Surface by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt does not rule out a professional job. We cut it out and start again.
