- Messy sealant that spoils new finishes
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Wipe joints with warm soapy water
- Get a leaking seal dealt with straight away
- Watch for new gaps as the house dries out
- Record problems with dated pictures
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
How we handle new build mastic in Upper Common
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. Typical jobs include new-build shower sealant that has already split and joints pulling apart as timber shrinks, across skirting & floors, windows & doors and show homes.
Somewhere as small as Upper Common, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Every job is covered by a 12-month guarantee.

What we can’t put right

- Damaged fittings that need replacing
- A tray or bath that is not properly supported, until it’s fixed

FAQs for Upper Common
Will you come out to Upper Common?

Do you work for landlords with property near Basingstoke station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Why has my new-build shower seal failed already?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.

What else we do in Upper Common
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Upper Common, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
How to prepare
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Do you need new build mastic in Upper Common?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
These are the problems we are asked about most:
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
- Frame joints opening as the plaster dries
If you’ve bought a new home near Basingstoke station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How the joint is cleaned and prepared
- Is VAT in the price?
- Which colour the sealant will be
