Why Choose Us
Why Next Level Sealants
The difference is in the preparation. Anyone can apply sealant. Getting it to last, seal properly and look right comes down to how the job is done from start to finish.
Proper Preparation
We remove old sealant completely and clean surfaces back to the substrate. No shortcuts, no patching over old material.
Right Product, Right Job
Silicone, polyurethane, polysulphide. We select the correct sealant for each application based on movement, substrate and exposure.
Clean, Neat Finish
Properly masked, neatly tooled, tidy site. A consistent bead that performs as well as it looks.

FAQ
Common Questions
Answers to the questions we get asked most. If yours isn't here, just get in touch.
Yes. We work on all kinds of commercial properties including offices, retail units, industrial buildings and new builds. We're used to working with property managers and main contractors.
Yes, bathroom and kitchen resealing is one of our most requested services. We remove all old sealant completely, prepare and clean the surfaces, then apply fresh silicone in a clean, consistent bead. Patching over old sealant is not something we do. It's done properly or not at all.
Yes. We work with developers and main contractors on new build developments of all sizes. We're used to working within site programmes and coordinating with other trades. Internal finishing, bathroom silicone, external mastic and window frame sealing are all things we handle regularly.
We're based in Liverpool and cover Merseyside and the wider North West including Crosby, Bootle, Formby, Southport, Wirral, St Helens, Warrington, Widnes, Runcorn and surrounding areas. If you're not sure, just ask.
Yes, for most jobs photos are the quickest way to get a price. Send them via WhatsApp, email or the contact form. We'll come back to you with a quote, or arrange a visit if we need to see it first.
Always. Old silicone must be fully removed before resealing. Applying new sealant on top of old will fail quickly and look poor. We remove everything down to the substrate, clean the surfaces properly, and only then apply the new sealant.
We use professional-grade sealants suited to each specific application. Silicone for bathrooms and wet areas, polyurethane and polysulphide for external and structural joints, and specialist products for expansion joints. We don't cut corners with materials.
Yes, we carry full public liability insurance for all work we carry out. Documentation can be provided for commercial and site-based work where required.
