New build mastic for homes and businesses in Kingston Stert
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on show homes, windows & doors and bathrooms & en suites, and the jobs we see most are untidy sealant flagged on a snagging list and cracks appearing as a new home settles.
Older homes in small places like Kingston Stert often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

New homes and floors in Kingston Stert
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.
If you’ve bought a new home near Princes Risborough station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why deal with it now?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like Kingston Stert, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

FAQs for Kingston Stert
Is Kingston Stert within the area you cover?
Yes, Kingston Stert is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Princes Risborough station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope for a clear quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Looking after it afterwards
After the cure time, these simple habits help:
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
- Resist patching a failed seal with a tube from the DIY shop
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Do you need new build mastic in Kingston Stert?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
People normally contact us when they notice one of these:
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
In and around Kingston Stert, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Comparing quotes
- How hidden problems are handled
- Who does the work, and how experienced they are
- How long the guarantee is
- Whether the sealant suits the joint
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What we cannot put right
New sealant cannot fix everything, and we will tell you before work begins. It will not solve:
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

What we do, step by step
Once we are on site, 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. In a small place like Kingston Stert, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We go through the snagging list or plot schedule and agree the joints to do.
- 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Mention if the joints have been sealed before
