When to call us in Holloway
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
It’s worth asking for a quote if you see:
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
- Cracks appearing as a new home settles
If you’ve bought a new home near Drayton Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we handle new build mastic in Holloway
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. Typical jobs include shower seals failing in the first year or two and kitchen sealant that has pulled off the wall, on show homes, bathrooms & en suites and skirting & floors.
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.
We stand behind the work with a one-year guarantee.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the quote in Holloway
Jobs vary more than people expect. What affects the quote:
- Which sealant suits the joint
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether the work is at height
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- What’s wrong with the joints now
- Whether it’s a home or a business
- The address or postcode of the job
If you are in Holloway and need new build mastic, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
What happens if it’s left?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or send us an email with a few pictures and we’ll tell you. In a flat in Holloway, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots. In Holloway, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

How the job changes by surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.

When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, before resealing.

Size, access and the old material all affect the cost. Call for a quick quote.
New homes and floors in Holloway
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Holloway can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
