When to call us in Runwell
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
Look out for these signs:
- Leaking shower tray seals in a new home
- Untidy sealant flagged on a snagging list
- Gaps opening as the house dries out and settles
- Frame joints opening as the plaster dries
For new homes near Wickford station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic for homes and businesses in Runwell
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 new bead bonds properly. We work on show homes, windows & doors and plot handovers, and people most often call us about kitchen sealant that has pulled off the wall and beads laid onto grit and dust from the build.
In smaller places like Runwell, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
A one-year guarantee comes as standard, so you’re covered after we have gone.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why deal with it now?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a smaller place like Runwell, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Landlord and commercial work in Runwell

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. We seal bathrooms, kitchens, frames and floors as agreed.
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
- Structural cracks in walls or ceilings
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Runwell questions
Can you help a landlord with a rental near Wickford station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you cover Runwell for new build mastic?
Yes, Runwell is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
How long will you be here?
That depends on the amount of work, but as a guide it takes a few hours in a single home. We’ll tell you when we quote.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early. Poor preparation at handover adds to it.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
New build mastic in Runwell: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
