How we handle new build mastic in Strettington
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on show homes, kitchens and plot handovers, and the jobs we see most are second-fix sealing on new plots and untidy sealant flagged on a snagging list.
For a small place like Strettington, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Raise failed sealant with the developer while you are covered
- Open a window or run the fan after bathing
- Keep water off fresh sealant until it has cured
- Do not seal over failed sealant yourself
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Older cottages and farmhouses around Strettington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Can I do it myself?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How it works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Strettington, 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.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
