New build mastic in Great Chesterford
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you have sealant that never bonded to the surface and cracks appearing as a new home settles, we can put it right, on bathrooms & en suites, kitchens and windows & doors alike.
Homes around Great Chesterford range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
We stand behind the work with a 12-month guarantee.

Do you need new build mastic in Great Chesterford?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
If you can see any of these, it’s time to have the joints looked at:
- Smeared, uneven beads picked up at snagging
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
Around Great Chesterford, as everywhere, new build mastic is only as good as the preparation behind it.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

Do you work for hotels and businesses?

Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.

Yes. Tell us about everything you’d like done and we will quote it together.

The process
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours in a single home for a typical job. A visit to Great Chesterford is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.

- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
- Resist patching a failed seal with a tube from the DIY shop
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you, so raise it early.
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Great Chesterford, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
