Sealant applicators in Colne Engaine

Failed sealant isn’t always the whole story. A leak near a frame edge can start in the frame, the cill or the cavity. We look before we quote and tell you plainly if sealant won’t solve it. Site teams most often ask us about untidy joints in a reception, shop floor or lobby and hardened, chalky sealant on south-facing or exposed elevations, across external facade joints, movement joints in walls and floors and kitchen worktops and splashbacks. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Colne Engaine is the same: the right product in a properly prepared joint.

Occupied buildings in Colne Engaine need the work phased: we agree the order with you and hand back each area with its cure time.

Business units in the countryside around places like Colne Engaine are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Cracking that needs a structural engineer to look at it
  • Roof leaks that only look like a joint problem
  • Faulty windows rather than failed perimeter sealant

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly.

What we seal

  • Movement joints in walls and floors
  • Washrooms and tea points
  • Kitchen worktops and splashbacks
  • External facade joints
  • Floor and threshold joints
  • Window and door perimeters

Sealant on show in Colne Engaine’s commercial buildings

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Keep abrasive pads and scrapers off resealed joints
  • Check sealant as part of routine building inspections
  • Log reseals in the O&M or maintenance records

Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a few hours for one area, or a planned series of visits across a bigger building. Rural sites near Colne Engaine may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions
  • Tell us what induction or permit system the site runs

Advice

Signs you need commercial sealant contractors in Colne Engaine

A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.

Most enquiries start with one or more of the following:

  • Black mould through washroom sealant that won’t clean off
  • Water staining near frames, panels or ceilings
  • Untidy joints in a reception, shop floor or lobby
  • Earlier reseals applied straight onto the failed bead

Parks like Riverside Business Park (to the south of Colne Engaine) see tenants come and go, and every move-in brings joints to seal.

Comparing quotes

  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS
  • Their plan for phasing and protecting the area

Why it’s worth doing now in Colne Engaine

Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s typically close behind, so access and set-up end up being paid for twice. We can price both options so you can decide on the facts. Around Colne Engaine, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why us?

  • Our applicators hold CSCS cards
  • Public liability insurance in place
  • Colours chosen to suit frames, cladding or finishes where possible
  • Workmanship guaranteed for 12 months

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Is failed sealant stripped out, or sealed over?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.
