About our new build mastic in Langenhoe
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. Common call-outs are for gaps between new skirting and floors and joints pulling apart as timber shrinks, across bathrooms & en suites, show homes and skirting & floors.
Around Langenhoe, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What new build mastic looks like in Langenhoe
Langenhoe is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Wivenhoe station, the sealant around baths, showers and frames is worth checking in the first year or two.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we are called out for in Langenhoe
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Keep an eye out for these signs:
- Kitchen sealant that has pulled off the wall
- Smeared, uneven beads picked up at snagging
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
In and around Langenhoe, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What else we do in Langenhoe
What we do, step by step
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work usually takes a few hours in a single home. Somewhere as small as Langenhoe, 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.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in

Related advice
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Don’t seal over failed sealant yourself
- Do not wait for the house to settle if water is getting through
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
Why it’s worth doing now in Langenhoe
A hairline gap at a skirting can wait, but water getting through cannot. If you are unsure which you have, ring 0345 464 0079 or send us an email with photos and we will tell you. Where a wall is exposed, as many are in small places like Langenhoe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
