About our new build mastic in Great Brickhill
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have leaking shower tray seals in a new home and sealant that never bonded to the surface, we can help, whatever the surface.
Older homes in small places like Great Brickhill often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Signs you need new build mastic in Great Brickhill
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.
Keep an eye out for any of the following:
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
If you’ve bought a new home near Bow Brickhill station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before you book anyone
- What insurance they hold
- Whether you can choose the colour
- How much experience the applicator has
- Is VAT in the price?
Aftercare tips
Good habits help new joints last longer. A few tips:
- Get a leaking seal dealt with straight away
- Raise failed sealant with the developer while you are covered
- Open a window or run the fan after bathing
- Wipe joints with warm soapy water
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Small faults turn into leaks if left.

Surface by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
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.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home, and the area is left clean. Somewhere as small as Great Brickhill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Mention any parking rules near the property
