Do you need new build mastic in Regents Park?
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Any of these means the joints need attention:
- Second-fix sealing on new plots
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
In and around Regents Park, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic for homes and businesses in Regents Park
We work in new homes and on new-build sites across Regents Park. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on windows & doors, show homes and bathrooms & en suites, and common reasons people get in touch are skirting joints opening in the first winter and joints pulling apart as timber shrinks.
In and around Regents Park, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

For new homes near Millbrook (Hants) station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Disputes or warranty claims with your builder
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Regents Park questions
Do you cover smaller places like Regents Park?
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.
Is Regents Park in your area for new build mastic?
Yes, Regents Park is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early. Poor preparation at handover adds to it.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you’re covered
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
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.
How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. A visit to Regents Park is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules
