How we handle new build mastic in Five Oaks
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on plot handovers, windows & doors and show homes, and the jobs we see most are plot mastic for developers ahead of handover and gaps behind new kitchen upstands.
For a small place like Five Oaks, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Each job carries a 12-month 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.
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 doesn’t work out, we can still put it right.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a village or hamlet like Five Oaks, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Mention any tricky access

What else we do in Five Oaks
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
- Clean sealant with mild detergent, not abrasives
- Keep water off fresh sealant until it has cured
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What the job involves on each surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can you do new build mastic in Five Oaks?
Yes. Our work covers London and the South East, and Five Oaks is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
How much does new build mastic cost in Five Oaks?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Five Oaks, along with the rest of our area.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Should I wait before resealing?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
How we quote for new build mastic
The quote reflects the job in front of us. We take into account:
