How we handle new build mastic in Kings Worthy
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We work on windows & doors, plot handovers and bathrooms & en suites, and people most often call us about kitchen sealant that has pulled off the wall and smeared, uneven beads picked up at snagging.
Around Kings Worthy, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Every job comes with our one-year guarantee.

Questions from Kings Worthy
Can you do new build mastic in Kings Worthy?

Can you help a landlord with a rental near Winchester station?

How long will you be here?

What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.
When to call us in Kings Worthy
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Signs it’s time to call us include:
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Messy sealant that spoils new finishes
- Leaking shower tray seals in a new home
If you’ve bought a new home near Winchester station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Kings Worthy, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

- Joints are vacuumed and cleaned of building dust.

Aftercare tips
A little care helps the new joints last. We recommend:
- Record problems with dated pictures
- Put sealant faults on your snagging list early
- Wipe joints with warm soapy water
- Wait for the cure time before using a resealed shower
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
Early snagging is easier snagging. Small faults turn into leaks if left.
