New build mastic for homes and businesses in Preston
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant generally lacks. We’re often asked to deal with messy sealant that spoils new finishes and skirting joints opening in the first winter, across show homes, kitchens and plot handovers.
In a village or hamlet like Preston, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
Common problems we fix in Preston
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry.
Look out for any of the following:
- Joints pulling apart as timber shrinks
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
- Gaps between new skirting and floors
If you’ve bought a new home near Hitchin station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Whether VAT is included
- Whether you can choose the colour
- Whether they seal over old material or remove it
- Whether the sealant suits the joint

The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. Somewhere like Preston needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- 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.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Preston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
