What we seal in shops and fit-outs

  • Counters, worktops and display units where they meet walls and floors
  • Shopfront frames and glazing, inside and out
  • Floor-to-wall, skirting and threshold joints
  • Wall panels, cladding and trims
  • Customer and staff toilets and staff kitchens
  • Fire-rated sealant where specified

A finish that matches the fit-out

In a shop, sealant is on show. We choose clear, white, grey, black or a colour to match the surfaces, and tool each joint neatly so it looks part of the fit-out rather than an afterthought. See colour-matched resealing.

Working to your programme

Fit-outs run to tight dates and shops often can’t close. We can work early, late or overnight where the site allows, and fit in with the other trades. Tell us the programme and the site rules when you ask for a quote.

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.
