Why it matters in a food business
Gaps in sealant collect food debris and moisture, harbour mould and bacteria and are hard to clean. Failed joints along worktops and around sinks also let water into the units behind. A neat, continuous bead is easier to wipe down and keeps water out. We use a food-safe product beside sinks and food areas where it’s needed, and anti-fungal sanitary silicone in washrooms.
Working around service
We know a kitchen can’t close for a day. We can start early, work between services or after closing, and do the job in sections so part of the kitchen stays in use. We’ll tell you how long each area needs to stay dry before it’s cleaned or used.
Before an inspection
If you have an inspection or audit coming up, tell us the date. We’ve resealed an office kitchen, shower rooms and an accessible wet room ahead of a health and safety audit, finishing before staff arrived. Food hygiene ratings are set by your local council; we can’t promise a rating, but tidy, sound sealant is one thing that’s easy to put right.
Paperwork and insurance
We’re fully insured for domestic, commercial and hospitality work. Tell us what your site needs, such as method statements, risk assessments or insurance details, and we’ll confirm what we can supply with the quote. Every job comes with our one-year guarantee, and we’re ARBOMaster approved applicators using Arbo and Everbuild products.
Quotes
We don’t publish set prices for commercial work, because every site is different. Tell us the site, what needs doing, roughly how much and your working hours, with photos or drawings if you have them. We’ll arrange a site visit where it’s needed and give you one clear quote before any work starts.
