How to look after the new joints
A little care helps the new joints last. We recommend:
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you’re covered
- Get a leaking seal dealt with right away
- Follow the cure time we give you
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
New build mastic in Hellman's Cross
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. If you are dealing with frame joints opening as the plaster dries and shower seals failing in the first year or two, we can put it right, on plot handovers, bathrooms & en suites and windows & doors alike.
In a village or hamlet like Hellman's Cross, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
There’s a 12-month guarantee on every job.

What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Can I send you my snagging list?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Should I go to my builder first?

Do you work for landlords and businesses?

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a small place like Hellman's Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Signs you need new build mastic in Hellman's Cross
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for these signs:
- Gaps opening as the house dries out and settles
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
- Internal frame sealant that has split
For new homes near Stansted Airport station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Whether they seal over old material or remove it
- Whether they’re fully insured

- How much experience the applicator has
The process
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Hellman's Cross 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.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
