Common Questions in Leigh
Practical details on quoting from photos, 24-hour curing times, full strip-out prep, and our 5-Year Domestic Guarantee across Leigh and nearby areas:
Do you cover Leigh, Lowton and Atherton for domestic bathroom resealing?+
Yes. We travel along the A580 corridor into Leigh (WN7), Lowton and Atherton every week for bathroom reseals, shower tile regrouting, kitchen worktops and whole-house renovation sealing.
Do you remove all the old sealant before resealing in Leigh?+
Always. We never silicone over existing silicone. The old sealant is 100% mechanically cut out, the joint is chemically sterilised to kill hidden mould spores, and fresh sanitary-grade silicone is applied.
How much does a bathroom reseal in Leigh cost?+
Most domestic bath and shower reseals are priced between £120 and £220 depending on the number of joints and substrate condition. Send 2 or 3 photos on WhatsApp for an exact fixed price before booking.
Can you replace black mouldy silicone around a shower or bath in Leigh?+
Yes. Once black mould penetrates beneath silicone, bleaching or surface scrubbing will not remove it. We mechanically slice away 100% of the mould-stained sealant in your Leigh home, sterilise the joint back to a dry substrate, and tool a crisp, antifungal trade silicone seal backed by our 5-Year Guarantee.
Can you fix a leaking shower tray or bath seal in Leigh?+
Yes. If water is escaping through split, peeling, or lifted silicone around your shower tray or bath edge, we extract the failed seal right back to bare tile, degrease the joint, and install a continuous watertight trade-grade silicone bead to protect your home from sub-floor water damage.
Do you reseal draughty or leaking UPVC window and door frames in Leigh?+
Yes. Perished external window and door mastic allows cold draughts, heat loss, and wind-driven rainwater into brickwork and reveals. We cleanly remove the cracked, decayed mastic and tool high-performance, weather-rated external frame sealant.
Is your domestic work in Leigh guaranteed?+
Yes. Every domestic silicone reseal in Leigh is backed by our official 5-year guarantee on adhesion and seal integrity. If our silicone ever peels, lifts, or detaches, send us a photo on WhatsApp and Liam will arrange a priority return visit completely free of charge (covers flexible silicone seals; rigid tile grout is excluded).
