Common questions in Bicester
Is new build mastic in Bicester guaranteed?
All our work, in Bicester and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
I let a flat near Bicester North station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I wait before resealing?
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.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
New build mastic in Bicester, done properly
Across Bicester, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on plot handovers, bathrooms & en suites and show homes, and common reasons people get in touch are gaps between new skirting and floors and leaking shower tray seals in a new home.
In a town like Bicester, older houses sit alongside newer estates, with new homes still going up on the edge of many towns. Whether a house is brand new or a few years old, sealant and floor joints are often the first snags to show.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
Good habits help new joints last longer. Our tips:
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Record problems with dated photos
- Do not seal over failed sealant yourself
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home.

What else we do in Bicester
What the job involves on each surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
Landlords, agents and businesses in Bicester
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
