New build mastic in Rushden, done properly
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. If you have smeared, uneven beads picked up at snagging and plot mastic for developers ahead of handover, we can put it right.
For a small place like Rushden, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, it’s backed by our one-year guarantee.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Rushden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. In a small place like Rushden, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Mention any parking rules near the property

When to call us in Rushden
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
For new homes near Baldock station, it’s worth checking the sealant early, while snags are still fresh.

Common questions in Rushden
I let a flat near Baldock station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do new build mastic in Rushden?
Yes. Our work covers London and the South East, and Rushden is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How do I get a quote for new build mastic in Rushden?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
How long will you be here?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.
Looking after it afterwards
To keep the joints looking good and working properly:
- Put sealant faults on your snagging list early
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
