About our new build mastic in Cross End
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on bathrooms & en suites, plot handovers and windows & doors, and common reasons people get in touch are gaps behind new kitchen upstands and leaking shower tray seals in a new home.
Around Cross End, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months.

Your questions about new build mastic in Cross End
I let a flat near Bures station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Is Cross End in your area for new build mastic?
Yes. We work across London and the South East, and Cross End is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Do you guarantee your work?
Yes. There’s a 12-month guarantee on every job.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you do plot mastic on a new development?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes a few hours in a single home. For a village or hamlet like Cross End, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.

When to call us in Cross End
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Common reasons people contact us include:
- Plot mastic for developers ahead of handover
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Gaps opening as the house dries out and settles
For new homes near Bures station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- When the joint can take water or movement
- Which colour the sealant will be
- Which sealant they’ll use, and why
- Whether VAT is included
What the job involves on each surface
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered to the agreed spec.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Which sealant suits the joint
- The number of rooms or windows
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The rough size of the job
- Photos by email, if that is easy
- Any access issues, like height or stairs
- If someone has resealed it before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
