New-build mastic & snagging in Marsh Gibbon, Oxfordshire
We cover Marsh Gibbon for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Messy sealant that spoils new finishes
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
What we cannot put right
Sealant is not the answer to every problem, and we will tell you before we start. It won’t solve:
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
- Baths and trays that move too much for sealant to cope with
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on
- Show homes

New build mastic in Marsh Gibbon
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We are often asked to deal with cracked sealant around new window and door frames and worktop and upstand sealant coming away, on kitchens, show homes and skirting & floors.
Around Marsh Gibbon, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, whatever its size.

Leave it or put it right?

- First we work through your snagging list or plot schedule with you.

Common questions in Marsh Gibbon
I let a flat near Bicester North station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Marsh Gibbon?
Yes. Marsh Gibbon is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Looking after it afterwards
After the cure time, these simple habits help:
- Put sealant faults on your snagging list early
- Avoid running a DIY bead over the old one
- Wait for the cure time before using a resealed shower
- Photograph failed sealant before it’s redone
Do not stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
