New build mastic in Enfield Highway, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We’re often asked to deal with smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands, on kitchens, windows & doors and bathrooms & en suites.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
There’s a 12-month guarantee on every job, whatever its size.

Why it’s worth doing now in Enfield Highway
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Enfield Highway, the repair is bigger than a sealant job.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- A choice of colours where the product allows

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. In a London area like Enfield Highway, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

New build mastic in Enfield Highway: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Enfield Highway is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Different surfaces, different methods
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Avoid scourers and strong chemicals on sealant
- Check bath and shower seals every few months as the house settles
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
When something else is needed
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Questions from Enfield Highway
Can parking be tricky for a visit in Enfield Highway?
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.
Do you work for landlords with property near Brimsdown station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Should I try it myself first?
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 fails, we can still redo it.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
