New build mastic in Lower Farringdon, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. We are often asked to deal with shower seals failing in the first year or two and sealant that never bonded to the surface, on windows & doors, skirting & floors and bathrooms & en suites.
Older homes in small places like Lower Farringdon often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, you get the same 12-month guarantee in Lower Farringdon and across Hampshire.

- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When something else is needed
We will not take on work that won’t last, so these are the limits:
- A tray or bath that isn’t properly supported, until it’s fixed
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Windows & doors
- Kitchens
- Show homes
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
Why it’s worth doing now in Lower Farringdon
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot. In a small place like Lower Farringdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Record problems with dated photos
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Clean sealant with mild detergent, not abrasives
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.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
