New build mastic in Oakthorpe Park, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. Common call-outs are for cracked sealant around new window and door frames and second-fix sealing on new plots, across skirting & floors, windows & doors and plot handovers.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover.
Each job carries a 12-month guarantee, whatever its size.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours in a single home from start to finish. In Oakthorpe Park, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Move anything stored near the joints

What we’re called out for in Oakthorpe Park
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Most people get in touch after spotting one of these:
- Joints pulling apart as timber shrinks
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- Cracked caulk along new skirting
If you’ve bought a new home near Palmers Green station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time. In a flat in Oakthorpe Park, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Neat joints and a tidy finish
- 20+ years of sealant experience
- Colour picked to suit the job
- Quality sealants from Arbo and Everbuild

Common questions in Oakthorpe Park
Can you help a landlord with a rental near Palmers Green station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is parking a problem for a job in Oakthorpe Park?
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.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
How do I get a quote for new build mastic in Oakthorpe Park?
Size, access and the old material all affect the cost. Ask us for a quote.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you when we finish.
Is there a guarantee?
Yes. Every job comes with our 12-month guarantee.
Can I do it myself?
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.

How to look after the new joints
So the new joints stay in good condition:
- Do not wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
