About our new build mastic in Turnpike Lane
Across Turnpike Lane, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on kitchens, plot handovers and show homes, and the jobs we see most are smeared, uneven beads picked up at snagging and sealant that never bonded to the surface.
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.
All of our work is guaranteed for twelve months, in Turnpike Lane and everywhere else we cover.

Why act early in Turnpike Lane
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What else we do in Turnpike Lane
What we are called out for in Turnpike Lane
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Any of these means the joints need attention:
- Plot mastic for developers ahead of handover
- Beads laid onto grit and dust from the build
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
If you’ve bought a new home near Hornsey station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- How much experience the applicator has
- Is VAT in the price?
- Whether all the old sealant comes out first
- How long to leave it before use
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Record problems with dated pictures
- Raise failed sealant with the developer while you’re covered
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What happens on the day
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take 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. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Tell us if parking is tricky

When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
Surface by surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
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.
Landlords, agents and businesses in Turnpike Lane
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Housing providers, facilities teams and property managers book us too in Turnpike Lane and across Greater London. Several sites can be quoted together, and we are fully insured for the work.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What new build mastic looks like in Turnpike Lane
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Turnpike Lane can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
