How we handle new build mastic in Riseley
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. If you are dealing with skirting joints opening in the first winter and frame joints opening as the plaster dries, we can put it right.
In a village or hamlet like Riseley, 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.
Your job is guaranteed for a year, as with all our work.

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. Older cottages and farmhouses around Riseley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs 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.

What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a small place like Riseley, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How do I get a quote for new build mastic in Riseley?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
Why has my new-build shower seal failed already?
It’s common, and there are generally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Put sealant faults on your snagging list early
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Ventilate bathrooms well, especially in the first year
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.

When to call us in Riseley
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
The most common problems we see are:
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
In and around Riseley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
