How we handle new build mastic in Chafford Hundred
Across Chafford Hundred, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on kitchens, show homes and skirting & floors, and common reasons people get in touch are new-build shower sealant that has already split and untidy sealant flagged on a snagging list.
Homes around Chafford Hundred range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. The sealant at skirtings and thresholds has to suit the floor it meets.
A one-year guarantee comes as standard, so you’re covered after we’ve gone.

Why it’s worth doing now in Chafford Hundred
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In an older home around Chafford Hundred, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

How to look after the new joints
So the new joints stay in good condition:
- Photograph failed sealant before it’s redone
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with right away
- Look at the sealant regularly in the first couple of years
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.
Chafford Hundred: your questions answered
Do you cover smaller places like Chafford Hundred?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do new build mastic in Chafford Hundred?
Yes, Chafford Hundred is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, large or small.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
When it is not the sealant
We won’t take on work that won’t last, so these are the limits:
- Broken tiles or a split tray
- Cracking that points to a structural problem
- A tray or bath that is not properly supported, until it’s fixed
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Joints and surfaces we work on
- Plot handovers
- Bathrooms & en suites
- Skirting & floors

Common problems we fix in Chafford Hundred
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.
The most common problems we see are:
- Leaking shower tray seals in a new home
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
- Sealant applied over dusty or wet surfaces
For new homes near Grays station, it’s worth checking the sealant early, while snags are still fresh.

How we quote for new build mastic
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- Mould in or behind the old joints
- Whether the work is at height
- The size of the job
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- The type of property
- How we’d reach the joints
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. In a smaller place like Chafford Hundred, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
