Domestic sealant FAQs
Common questions.
We cover Mastic Man Liverpool and all L postcodes alongside St Helens, Warrington, Wigan, Widnes, Runcorn, Southport, Ormskirk, Crosby, Formby, the Wirral and surrounding North West areas.
Is your domestic sealant work guaranteed?+
Yes. All residential bathroom, shower, kitchen, window and floor resealing is backed by our Next Level 5-Year Workmanship & Adhesion Guarantee. If our sealant peels, lifts, or detaches under normal household use, we return and reseal it 100% free of charge.
Can you quote from photographs?+
Yes. Most domestic jobs can be priced from clear photos and your postcode sent by WhatsApp or our quote form. You will know the exact price before anything is booked.
Do you remove old silicone before resealing?+
Always. New silicone applied over old, mouldy sealant will peel and fail quickly. We strip the old bead right back to a clean surface before applying fresh sealant.
Can you match the colour to my tiles, floor or worktop?+
Yes. We carry a wide range of trade silicone and mastic colours to match white sanitaryware, grey or beige tiles, oak or stone worktops, and anthracite or timber window frames.
Which areas do you cover for domestic work?+
We cover Liverpool, St Helens, Warrington, Wigan, Widnes, Runcorn, Southport, Ormskirk, Crosby, Formby, the Wirral, Cheshire, Greater Manchester and Merseyside.
Every Domestic Reseal Backed by Our 5-Year Guarantee.
We do not cap fresh silicone over old sealant. Because we cut out all failed material, solvent clean the joint and apply professional trade silicone, our sealant stays bonded. If it ever fails under normal domestic use, we return and replace it 100% free of charge.
Applies to all domestic bathroom, shower, kitchen, window, door, and floor perimeter silicone resealing (excludes rigid cementitious tile grout). Commercial projects carry standard 12-month DLP.
Why Next Level Can Guarantee Adhesion
Most handymen charge £50 to pump fresh silicone over mouldy old beads in 15 minutes. It peels in 3 months.
Full Mechanical Strip-Out
Every failed millimeter is removed right back to bare tile, acrylic, and frame.
Solvent Degreasing & Dry Prep
Silicone can only bond to chemically clean surfaces. We scrub soap scum and dry completely.
Pure Low-Shrinkage Silicones
Trade cartridges with active fungicides that flex with movement without splitting.
