About our new build mastic in Havering-atte-Bower
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. Common call-outs are for skirting joints opening in the first winter and cracks appearing as a new home settles, on skirting & floors, kitchens and bathrooms & en suites.
Older homes in small places like Havering-atte-Bower often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

- Skirting joints opening in the first winter
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
In and around Havering-atte-Bower, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step

We protect the rest, and the work takes a few hours for most snagging lists, longer for a run of plots in most cases. In a small place like Havering-atte-Bower, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- 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.

What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Older cottages and farmhouses around Havering-atte-Bower can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

- Structural cracks in walls or ceilings
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out and baths are filled before sealing.
Aftercare tips
So the new joints stay in good condition:
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
- Get a leaking seal dealt with right away
- Report sealant problems to your builder during the snagging period
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 seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
