New-build mastic & snagging in Galleywood, Essex
New-build sealant joints in Galleywood need attention? We remove the old material, prepare the joints and seal them properly.
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
- Second-fix sealing on new plots
How we handle new build mastic in Galleywood
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have shower seals failing in the first year or two and cracks appearing as a new home settles, we can put it right, whatever the surface.
Homes around Galleywood range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

What we are called out for in Galleywood
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
If you can see any of these, it’s time to have the joints looked at:
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
For new homes near Chelmsford station, it’s worth checking the sealant early, while snags are still fresh.

Galleywood questions
Do you work for landlords with property near Chelmsford station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Galleywood?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you match the sealant colour to my new kitchen or bathroom?
The colour is chosen to suit the tiles, worktop or frame. Tell us what you’d like when you get a quote.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does the job take?
Most jobs take a few hours in a single home. We will confirm how long when we quote.
Why does sealant fail so quickly in new builds?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
- Plumbing faults behind the sealant
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
What we seal
- Plot handovers
- Show homes
- Skirting & floors
- Windows & doors

- Bathrooms & en suites
Looking after it afterwards
Aftercare is simple:
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For a job in Galleywood, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Tell us about any water getting in

Leave it or put it right?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Homes in smaller places like Galleywood can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
