New build mastic in Eynsham
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. We work on show homes, plot handovers and windows & doors, and common reasons people get in touch are sealant applied over dusty or wet surfaces and cracks appearing as a new home settles.
If you’ve bought a new home in or near Eynsham, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
Big or small, it’s backed by our one-year guarantee in Eynsham and across Oxfordshire.

How it works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. For a job in Eynsham, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

Eynsham questions

Can you do new build mastic in Eynsham?

Are you insured?
Yes. We’re fully insured for every job we do.
How much does new build mastic cost in Eynsham?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Looking after it afterwards
So the new joints stay in good condition:
- Use the extractor fan every time you shower
- Don’t wait for the house to settle if water is getting through
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you’re covered
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
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
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. We’ll plan around viewing times.
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In an older home around Eynsham, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Do you need new build mastic in Eynsham?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Skirting joints opening in the first winter
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
Around Eynsham, as everywhere, new build mastic is only as good as the preparation behind it.

What we cannot put right
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.
