How we handle new build mastic in Jennett's Park
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. Common call-outs are for messy sealant that spoils new finishes and plot mastic for developers ahead of handover, across kitchens, show homes and bathrooms & en suites.
In smaller places like Jennett's Park, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
We stand behind the work with a one-year guarantee.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. In a smaller place like Jennett's Park, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Move anything stored near the joints

What we’re called out for in Jennett's Park
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Signs it’s time to call us include:
- Frame joints opening as the plaster dries
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
For new homes near Martins Heron station, it’s worth checking the sealant early, while snags are still fresh.

How the job changes by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and prime where the product needs it.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.
New build mastic in Jennett's Park: local notes
Jennett's Park is part of Bracknell, one of the post-war new towns. Bracknell has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Common questions in Jennett's Park
I let a flat near Martins Heron station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Is Jennett's Park in your area for new build mastic?
Yes, Jennett's 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 let us know what needs doing, and we will give you a clear quote.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I go to my builder first?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.

What else we do in Jennett's Park
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Use the extractor fan every time you shower
- Get a leaking seal dealt with right away
- Watch for new gaps as the house dries out
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
