What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Roof leaks that only look like a joint problem
  • Leaks from pipework, wastes or valves (that’s plumbing)

If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.

Where we work in Caldecote

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

Commercial sealant contractors for commercial buildings in Caldecote

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. We work on external facade joints, floor and threshold joints and window and door perimeters, and the failures we’re asked to look at most are weathered facade sealant that no longer flexes and movement joints packed with grit and debris. A specialist sealant contractor works differently from a general builder: in Caldecote, that means joint design, primers and backing rod as standard.

Multi-site clients with buildings in and around Caldecote can put several sites on one programme, with one quote format and one point of contact.

Business units in the countryside around places like Caldecote 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.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Common problems we fix in Caldecote

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges. A hardened bead can’t follow the building any more.

Any of the following is a good reason to get the joints checked over:

  • Black mould through washroom sealant that won’t clean off
  • Gaps behind commercial kitchen worktops and sinks
  • Frame mastic that has hardened and come away from the wall
  • External beads that have gone brittle and cracked

Occupiers with premises at both Cromwell Business Park and Blakelands Industrial Estate could have the sealant at each handled under one quote.

Choosing a commercial sealant contractor

FAQs: Caldecote

Will our hotel in Caldecote need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

Do you cover business parks and estates near Caldecote, such as Cromwell Business Park?

Yes. We cover Caldecote and the area around it, including industrial estates, business parks and retail parks such as Cromwell Business Park. Photos and a short description are enough for a first look.

Does commercial sealant work come with a guarantee?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

Do you check for asbestos before removing sealant?

We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Which site documents can you send us?

We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

Is failed sealant stripped out, or sealed over?

Full removal is part of every quote. Sealing over traps water and lifts once the joint moves.

Frontages, fit-outs and joints in Caldecote

Less than 3 miles from Caldecote there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

Multi-site occupiers here often want one sealant contractor across all their buildings.

In hotels such as Swan Revived Hotel, 1 mile north of Caldecote, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. If you run an office at a site such as Cromwell Business Park (0.9 miles north-east of Caldecote), the sealant at reception desks, tea points and frames ages with each fit-out.

Doing it in-house

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Different surfaces, different methods

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed.

Fire-rated seals where specified

Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, and we’ll tell you if the detail calls for something else.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Caldecote, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. We strip the failed bead and prepare both faces of the joint.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Preparing the site

  • Agree which areas must stay open
  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs
