West Liss New Build Mastic
Our applicators work in West Liss on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Cracked caulk along new skirting
- Shower seals failing in the first year or two
- Gaps opening as the house dries out and settles
New build mastic in West Liss
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. We are often asked to deal with kitchen sealant that has pulled off the wall and sealant work across a run of new homes, across show homes, bathrooms & en suites and kitchens.
Older homes in small places like West Liss often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Big or small, you get the same one-year guarantee.

Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. Older cottages and farmhouses around West Liss can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?
- Any old sealant cut out fully, not covered over
- Quality sealants from Arbo and Everbuild
- A choice of colours where the product allows
- Neat joints and a tidy finish
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.

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. In total, it generally takes a few hours in a single home. In a small place like West Liss, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Finally, each room is checked and you’re given the cure time.

Related advice
Do you need new build mastic in West Liss?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
Look out for these signs:
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
For new homes near Liss station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in West Liss: local notes

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Record problems with dated photos
- Resist patching a failed seal with a tube from the DIY shop
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you, so raise it early.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
