Scope of Work
What We Reseal
Say goodbye to unsightly black mould, peeling silicone, and leaking shower trays. When bathroom sealant fails, water doesn't just sit on the surface—it seeps into wall cavities, rots timber floorboards, and causes expensive ceiling leaks below. Led by Liam, our family-run team never skims fresh silicone over old sealant. We mechanically strip out all failed material down to clean substrate, treat the joint with commercial anti-fungal washes, and apply premium sanitary silicone with active biocides. You get crisp, bubble-free, razor-sharp lines that stay watertight and mould-free for years—backed by our written 5-Year Domestic Guarantee with free return visits.

When to Call Us
Common Bathroom & Kitchen Issues
Black mould and mildew inside the silicone bead
01Scrubbing and bleaching cannot remove black mould once spores penetrate into the silicone core. We mechanically extract 100% of the contaminated bead, sterilise the joint with hospital-grade biocidal washes, and install fresh anti-fungal sanitary silicone that actively resists mould.
Failed shower tray and bath perimeter seals
02Failed or cracked perimeter seals let shower water seep down behind tiles, soaking ceiling plasterboard below. We establish an elastomeric, watertight seal with ±25% movement capability that flexes safely under water and body weight.
Peeling, shrunken, or stained kitchen worktop seals
03Kitchen worktop silicone shrinks and lifts over time, trapping food grease and dirty sink water. We cleanly slice out the old bead and reseal with certified food-safe, non-staining neutral cure silicone that will not discolour marble or quartz.
Crumbling or cracked tile grout in showers
04Grout is rigid and cracks in corners where walls meet. We rake out failed corner grout and replace it with flexible sanitary silicone, with optional full wall regrouting by our in-house master craftsman Vinny (22+ years experience).
Our Process
How We Do the Job
100% Mechanical Strip-Out
We cleanly slice away all existing failed silicone down to bare substrate. Patching or skimming fresh silicone over old sealant is something we never do.
Biocidal Wash & Solvent Degrease
The joint interface is treated with commercial anti-fungal wash to eradicate deep-seated mould spores, then degreased with fast-flashing industrial solvents.
Extrude Commercial Sanitary Silicone
We apply premium trade-only sanitary silicone formulated with active fungicides, using high-thrust extrusion guns for a dense, continuous, bubble-free bead.
Specialist Profiling & 5-Year Guarantee
The bead is hand-tooled with calibrated profiling spatulas to create a laser-straight concave water-shedding line, backed by our written 5-Year Domestic Guarantee.

Great price
“Liam did a great job, he completely sealed my bathroom/wetroom. I’m really particular and there isn’t a bump or an uneven patch anywhere. Lovely lad would 💯 recommend!”

“Liam did a great job sealing our bathroom. It was left in a mess by the previous owners but Liam came and swiftly cut out the old sealant and resealed it beautifully in only a couple of hours. The bathroom has now been transformed! Would highly recommend and really reasonable price.”
Chavonne Graham

“Liam did such a brilliant job on our new bathroom. We’d had the silicone done already but weren’t happy with the finish, and he came in and sorted it all out for us. It looks so much neater now and has made a massive difference to the room. Really friendly, tidy and clearly knows what he’s doing. We’ll definitely be getting him back once the shower screen and toilet are fitted. Would 100% recommend 👍 thank you so much Liam.”

FAQ
Common Questions
Have another question about your job? Send a photo on WhatsApp or use our quote form and we will help straight away.
Do you remove old silicone first?+
Always. Skimming new silicone over old silicone is guaranteed to peel and fail within weeks. We mechanically remove 100% of existing silicone down to bare substrate, clean and degrease the joint, and apply fresh trade-grade sanitary silicone.
Do you also regrout bathroom and shower tiles?+
Yes. Alongside silicone resealing, we offer specialist bathroom, shower and kitchen tile regrouting led by our in-house craftsman Vinny (22+ years experience). A combined regrout and reseal transforms your entire shower in one day, saving £3,000 to £7,000 over retiling.
Can you quote from photos?+
Yes. Simply take 2 or 3 clear photos of your bath, shower tray or kitchen worktop on your phone and send them with your postcode on WhatsApp to Liam. We provide an exact fixed price before you book.
When can I use the shower or bath after resealing?+
We recommend waiting 24 hours after completion before using the shower or bath. This allows the sanitary silicone to cure completely through the bead, ensuring maximum waterproof adhesion.
What does your 5-Year Domestic Guarantee cover?+
Our guarantee covers the adhesion and waterproof integrity of all newly installed domestic silicone joints. If our sealant ever peels, shrinks or detaches under normal domestic use within 5 years, we return and replace it completely free of charge.

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
