Oxford New Build Mastic
We cover Oxford for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
New build mastic in Oxford, done properly
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. If you have internal frame sealant that has split and beads laid onto grit and dust from the build, we can help, whatever the surface.
Oxford has plenty of estates from recent decades, where the builder’s original sealant around baths, frames and skirtings may be due for replacing. Snagging and second-fix sealing are part of what we do for developers and new-home owners alike.
You are covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Landlords, agents and businesses in Oxford
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
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.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. For homes and businesses in busier parts of Oxford, parking needs a little planning. For flats, mention stairs, lifts and shared entrances as well.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Questions from Oxford
Do you work for landlords with property near Oxford station?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is there a guarantee on new build mastic in Oxford?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is it worth trying 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.
What colour sealant will you use?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

How the job changes by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one.
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Signs you need new build mastic in Oxford
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry first.
It’s worth asking for a quote if you see:
- Gaps opening as the house dries out and settles
- Beads laid onto grit and dust from the build
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
If you’ve bought a new home near Oxford station, the sealant around baths, showers and frames is worth checking in the first year or two.
