What we need to know
Photos help, but a description is a good start. Please mention:

- Photos by email, if that’s easy

New build mastic for homes and businesses in North Ockendon
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. Common call-outs are for worktop and upstand sealant coming away and beads laid onto grit and dust from the build, on kitchens, skirting & floors and windows & doors.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Your questions about new build mastic in North Ockendon
I let a flat near Ockendon station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Is parking a problem for a job in North Ockendon?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
How long does new build mastic take?
That depends on the amount of work, but as a guide it takes a few hours in a single home. We will tell you when we quote.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Landlords, agents and businesses in North Ockendon
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Other services in North Ockendon
Different surfaces, different methods
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
- Cracked trays, tiles or worktops
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Show homes
- Kitchens
- Windows & doors
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
Keeping the joints in good condition
After the cure time, these simple habits help:
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
- Act quickly if a seal starts to leak
- Record problems with dated pictures
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Small faults turn into leaks if left over time.
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job generally takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. For a job in North Ockendon, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Mention any parking rules near the property

Advice
Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a flat in North Ockendon, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Why choose Mr Mastic in North Ockendon
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator
- Colour agreed with you before any work starts
