About our new build mastic in West Hanney
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have cracks appearing as a new home settles and sealant that never bonded to the surface, we can help, on kitchens, show homes and skirting & floors alike.
Work in a small place like West Hanney just needs the journey and access planning, and once on site, the job is the same as anywhere.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

For a village or hamlet like West Hanney, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.

West Hanney questions
What guarantee comes with new build mastic in West Hanney?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover West Hanney for new build mastic?
Yes. We work across London and the South East, and West Hanney is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early as timber and plaster dry out. Poor preparation at handover adds to it.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you work through snagging lists?
Yes. Send the list and a few photos of the sealant items. We’ll tell you if anything on it is not a sealant job.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t seal over failed sealant yourself
- Put sealant faults on your snagging list early
- Wait for the cure time before using a resealed shower
- Keep pictures and emails about snagging items
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.
Different surfaces, different methods
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
