Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot. In a small place like Stonegate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

New build mastic in Stonegate
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you’re dealing with internal frame sealant that has split and joints pulling apart as timber shrinks, we can help.
Older homes in small places like Stonegate often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You get a one-year guarantee, the same in Stonegate as everywhere else we work.

What affects the quote in Stonegate
For a quick quote, just ask. What matters most is:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- The size of the job
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
To make quoting easier, let us know:
- Whether it’s a home or a business
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.
Signs you need new build mastic in Stonegate
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 and can tear.
Look out for these signs:
- Frame joints opening as the plaster dries
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- Leaking shower tray seals in a new home
For new homes near Stonegate station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- What preparation is included
- Whether they’re fully insured
- How the colour is chosen
- Whether the sealant suits the joint
How the job changes by surface
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and prime where the product needs it.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
- 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. Most silicones need around a day to cure enough for use.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
Can I do it myself?
What a professional job adds is preparation and the right 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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Stonegate: your questions answered
Is Stonegate within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Stonegate for new build mastic?
Yes, Stonegate is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Are you insured?
Yes, we are fully insured for domestic and commercial work.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
How it works
The work is kept neat and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. In a small place like Stonegate, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
Ask for a quote
