About our new build mastic in Walderslade
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on kitchens, plot handovers and bathrooms & en suites, and the jobs we see most are joints pulling apart as timber shrinks and cracked sealant around new window and door frames.
In smaller places like Walderslade, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. A visit to Walderslade is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as 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.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on

Advice
Why act early in Walderslade
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Homes in smaller places like Walderslade can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Internal frame sealant that has split
- Untidy sealant flagged on a snagging list
- Sealant that never bonded to the surface
If you’ve bought a new home near Chatham station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
