New build mastic in Wooburn, done properly
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you are dealing with sealant work across a run of new homes and untidy sealant flagged on a snagging list, we can put it right, on plot handovers, bathrooms & en suites and skirting & floors alike.
For a small place like Wooburn, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Your job is guaranteed for a year, as with all our work.

Signs you need new build mastic in Wooburn
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
The most common problems we see are:
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Bourne End station, the sealant around baths, showers and frames is worth checking in the first year or two.

Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
FAQs for Wooburn
Can you do new build mastic in Wooburn?
Yes, Wooburn is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Will you come out to Wooburn?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours in a single home, and the area is left clean. Somewhere like Wooburn needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
