New build mastic for homes and businesses in Patching
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. Common call-outs are for new-build shower sealant that has already split and gaps between new skirting and floors, across skirting & floors, kitchens and plot handovers.
Older homes in small places like Patching often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What else we do in Patching
How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- The number and length of the joints
- Any working-time requirements on site
- Whether there’s mould to deal with
- The old material and how stubborn it is
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
What we need to know
What to tell us when you ask for a quote:
- How we’d reach the joints
- The type of property
- The rough size of the job
- The problem you’ve noticed
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Get a leaking seal dealt with straight away
- Record problems with dated photos
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
Do not stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
Questions from Patching
Do you work for landlords with property near Goring-By-Sea station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Can you do new build mastic in Patching?
Yes. We work across London and the South East, and Patching is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
How long will you be here?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the number of plots. We will give you a better idea when we quote.
How much does new build mastic cost in Patching?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or email us and tell us what needs doing and where.
Do you work for developers?
Yes. We work through plots to your schedule. Tell us the plots and the joints involved and we’ll quote.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. If that does not work out, we are happy to quote.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
What the job involves on each surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Patching, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
Ask for a quote
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved.
Related advice
What we can’t put right
New sealant cannot fix everything, and we will tell you before any work starts. Sealant will not put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

What we’re called out for in Patching
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Keep an eye out for these signs:
- New-build shower sealant that has already split
- Internal frame sealant that has split
- Cracked caulk along new skirting
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Goring-By-Sea station, the sealant around baths, showers and frames is worth checking in the first year or two.
