New build mastic in Addington
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for cracked sealant around new window and door frames and leaking shower tray seals in a new home, across plot handovers, bathrooms & en suites and windows & doors.
In a village or hamlet like Addington, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
All our work comes with our 12-month guarantee, wherever you are in Kent.

How to look after the new joints
To keep the joints looking good and working properly:
- Resist patching a failed seal with a tube from the DIY shop
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
- Clean sealant with mild detergent, not abrasives
Watch the joints as the house settles. Small gaps can appear as the house dries.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
How we quote for new build mastic
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint
- Whether there’s mould to deal with
- Working hours on commercial sites
- How many rooms, windows or areas are involved
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or drop us an email.
When to call us in Addington
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
The most common problems we see are:
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
For new homes near West Malling station, it’s worth checking the sealant early, while snags are still fresh.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Addington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- 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.
- The finished joints are checked and the cure times given.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

What the job involves on each surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.

Other services in Addington
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, 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.
