How we handle new build mastic in Cocking Causeway
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have gaps between new skirting and floors and worktop and upstand sealant coming away, we can help, on bathrooms & en suites, windows & doors and skirting & floors alike.
Older homes in small places like Cocking Causeway often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Why it’s worth doing now in Cocking Causeway
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Around Cocking Causeway, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

When to call us in Cocking Causeway
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
The problems people normally mention when they call include:
- Skirting joints opening in the first winter
- Smeared, uneven beads picked up at snagging
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
For jobs in and around Cocking Causeway, choosing the right material for each joint is as important as a tidy finish.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What we need to know
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or drop us an email with the details and send pictures if you have them.
The process
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job generally takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. In a small place like Cocking Causeway, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare

Related advice
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
