New-build mastic & snagging in Broxbourne, Hertfordshire
Our applicators work in Broxbourne on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
- Messy sealant that spoils new finishes
Why act early in Broxbourne
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you are unsure which you have, phone 0345 464 0079 or drop us an email with pictures. In an older home around Broxbourne, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

How we handle new build mastic in Broxbourne
Across Broxbourne, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We’re often asked to deal with shower seals failing in the first year or two and beads laid onto grit and dust from the build, on skirting & floors, plot handovers and kitchens.
For a new home in or near Broxbourne, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Parking around Broxbourne is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Open a window or run the fan after bathing
- Get a leaking seal dealt with straight away
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
What sealant work cannot fix
In fairness, there are a few things sealant won’t fix:
- Your warranty claim itself, which is between you and the builder
- Structural cracks in walls or ceilings
- Movement caused by a poorly fitted tray or bath
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Windows & doors
- Skirting & floors
- Plot handovers
- Bathrooms & en suites

Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
