How we handle new build mastic in Coldred
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you are dealing with gaps behind new kitchen upstands and new-build shower sealant that has already split, we can help, on show homes, windows & doors and kitchens alike.
Older homes in small places like Coldred often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a 12-month guarantee, the same in Coldred as everywhere else we work.

The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on the number of plots, including the tidy-up. Somewhere as small as Coldred, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Mention if the joints have been sealed before

Do you need new build mastic in Coldred?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
People normally contact us when they notice one of these:
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
- Second-fix sealing on new plots
In and around Coldred, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
To keep the joints looking good and working properly:
- Resist patching a failed seal with a tube from the DIY shop
- Ventilate bathrooms well, especially in the first year
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Older cottages and farmhouses around Coldred can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
