New build mastic for homes and businesses in Brookmans Park
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on show homes, kitchens and windows & doors, and people most often call us about cracked caulk along new skirting and gaps behind new kitchen upstands.
Around Brookmans Park, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Different surfaces, different methods
Show homes
We seal show-home bathrooms, kitchens and frames. We will plan around viewing times.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Do you need new build mastic in Brookmans Park?
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that cannot keep up splits.
People usually contact us when they notice something like this:
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- Sealant that never bonded to the surface
In and around Brookmans Park, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Brookmans Park, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
