New build mastic for homes and businesses in Leeds
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. Common call-outs are for sealant applied over dusty or wet surfaces and leaking shower tray seals in a new home, across windows & doors, plot handovers and show homes.
Around Leeds, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months.

Landlords, agents and businesses in Leeds
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for property managers and facilities teams in Leeds and across Kent. Several sites can be quoted together, and we’re fully insured for the work.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Somewhere like Leeds needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.

What affects the quote in Leeds
Your quote is based on your job. We take into account:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether the work is at height
- Which sealant suits the joint
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email.
What we need to know
You do not need to know the technical terms. It helps if you can tell us:
- How we’d reach the joints

- Where the property is
- If it’s domestic, commercial or a hotel
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Avoid scourers and strong chemicals on sealant
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Do you need new build mastic in Leeds?
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.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between new skirting and floors
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
For new homes near Hollingbourne station, it’s worth checking the sealant early, while snags are still fresh.

Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
