DIY sealant or a professional job?
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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
New build mastic in Duddleswell, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you have sealant that never bonded to the surface and gaps between new skirting and floors, we can help, whatever the surface.
Somewhere as small as Duddleswell, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Photograph failed sealant before it’s redone
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
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.

What affects the cost of new build mastic

- The old material and how stubborn it is
- Whether the work is at height
- How many rooms, windows or areas are involved

How it works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. In a small place like Duddleswell, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
