What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around King Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear price before we start.
What you get with us
- Every job guaranteed for a year
- An ARBOMaster approved applicator

New build mastic for homes and businesses in King Street
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on bathrooms & en suites, plot handovers and kitchens, and the jobs we see most are worktop and upstand sealant coming away and cracked caulk along new skirting.
Around King Street, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours in a single home. Somewhere as small as King Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Broken tiles or a split tray
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

Questions from King Street
Will you come out to King Street?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Ingatestone station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. If it isn’t resolved, we will cut it out and reseal it.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early, because the house is drying and settling. Poor preparation at handover adds to it.
Quotes for new build mastic in King Street
There’s no set price list. What we look at:
- How much old sealant there is and how hard it is to remove
- The amount of work
- The product the joint needs
- Any working-time requirements on site
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
To make quoting easier, please include:
- Where the property is
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- The rough size of the job
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Don’t wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

How the job changes by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out with baths filled first.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
