New build mastic in Maynard's Green, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have smeared, uneven beads picked up at snagging and frame joints opening as the plaster dries, we can help, on skirting & floors, show homes and kitchens alike.
Work in a small place like Maynard's Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What else we do in Maynard's Green
How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. Somewhere as small as Maynard's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- 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.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

Advice
Common questions in Maynard's Green
Can you do new build mastic in Maynard's Green?
Yes, Maynard's Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Maynard's Green?
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 take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Maynard's Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
