How we handle new build mastic in Oakwood
Across Oakwood, 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: remove, clean, prime where needed, then a neat new bead. If you’re dealing with frame joints opening as the plaster dries and plot mastic for developers ahead of handover, we can help, on skirting & floors, windows & doors and show homes alike.
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, in Oakwood and beyond.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Signs you need new build mastic in Oakwood
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Messy sealant that spoils new finishes
- Cracks appearing as a new home settles
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
If you’ve bought a new home near Winchmore Hill station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before booking
- Are they insured?
- What preparation is included
- How much experience the applicator has
- Which sealant they’ll use, and why
Questions from Oakwood
Is parking a problem for a job in Oakwood?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you cover Oakwood for new build mastic?
Yes. Our work covers London and the South East, and Oakwood is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, large or small.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work from my snagging list?
Yes. Send it with pictures and we will quote for the sealant items. If something isn’t sealant, we’ll say so.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
If you’re 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.

New build mastic around Oakwood
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.
As a London address, Oakwood can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Open a window or run the fan after bathing
- Clean sealant with mild detergent, not abrasives
- Watch for new gaps as the house dries out
- Keep photos and emails about snagging items
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day to cure enough for use.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home and we leave things clean and tidy. In Oakwood, 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 start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

Advice
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time and most come down to preparation. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Oakwood, the repair is bigger than the sealant job would have been.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
