New build mastic in Nash
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We’re often asked to deal with beads laid onto grit and dust from the build and gaps behind new kitchen upstands, on plot handovers, kitchens and skirting & floors.
Somewhere as small as Nash, 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.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Why it’s worth doing now in Nash
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Around Nash, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Does someone need to be in?

Are you insured?

Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.
Is it worth resealing while the house is still settling?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day to cure enough for use.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.

How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. The work normally takes anything from a few hours to several days, depending on the number of plots. Somewhere like Nash needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Surface by surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
