How we handle new build mastic in Catherington
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. If you have smeared, uneven beads picked up at snagging and skirting joints opening in the first winter, we can help, on skirting & floors, kitchens and plot handovers alike.
In a village or hamlet like Catherington, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for Catherington
Do you cover smaller places like Catherington?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Rowlands Castle station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.
Do you work through snagging lists?
Yes. We often work straight from a snagging list. We agree the sealant items with you before any work starts.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Landlords, agents and businesses in Catherington
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

Surface by surface
Show homes
We seal show-home bathrooms, kitchens and frames to a tidy standard. We’ll plan around viewing times.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Raise failed sealant with the developer while you’re covered
- Do not wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most snagging lists, longer for a run of plots. In a small place like Catherington, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work

Advice
Why act early in Catherington
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Catherington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Cracking that points to a structural problem
- Deciding who is responsible under a builder’s warranty
- Leaking fittings rather than failed sealant
