About our new build mastic in Cadmore End
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. If you have leaking shower tray seals in a new home and cracked caulk along new skirting, we can help, on windows & doors, bathrooms & en suites and plot handovers alike.
Work in a small place like Cadmore End just needs the journey and access planning, and the work itself is the same as on any site.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Your questions about new build mastic in Cadmore End
Do you cover smaller places like Cadmore End?
Yes. Cadmore End is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Cadmore End for new build mastic?
Yes. We work across London and the South East, and Cadmore End is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
What should I tell you?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
Who should fix failed sealant in a new build?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we will say how long yours will take.
Can you work from my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. In a small place like Cadmore End, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Full insurance on every job
- ARBOMaster approved applicator
- Homes, businesses and hotels
- Every job guaranteed for a year

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
What happens on the day
The work is kept neat and contained to the area we are working on. The job usually takes a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. Somewhere as small as Cadmore End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

Do you need new build mastic in Cadmore End?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
The most common problems we see are:
- Beads laid onto grit and dust from the build
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
Around Cadmore End, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- When the joint can take water or movement
- Are they insured?
- Whether the sealant suits the joint
- Whether they seal over old material or remove it

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. 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, 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.
