New build mastic in Emerson Park, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. Common call-outs are for beads laid onto grit and dust from the build and gaps behind new kitchen upstands, across windows & doors, plot handovers and kitchens.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

What happens on the day
We work through the job in order: 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. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Emerson Park. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Let us know about parking restrictions

Advice
How the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed so the sealant lasts.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Common questions in Emerson Park
Do you work for landlords with property near Emerson Park 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 will give you a clear quote.
Can parking be tricky for a visit in Emerson Park?
Parking in Emerson Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months, wherever you are.
Where do you work from?
Mr Mastic is based in Crawley. We cover Emerson Park and the rest of Greater London, along with the rest of our area.
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.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. Once that is done, or if they won’t put it right, we can reseal it properly.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated pictures
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we cannot put right
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Cracked trays, tiles or worktops
- A tray or bath that is not properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, call 0345 464 0079 or email us and we will say what we think.
