Commercial sealant contractors around Caterham: points for this area

At least three named trading, business or retail sites lie within about 3 miles of Caterham. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies. Rainfall across the South East, Caterham included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

Units at retail parks like Church Walk Shopping Centre (to the south-east of Caterham) change hands and get refitted, with new joints at every frontage. Shops and cafés around stations like Caterham station (to the south-east of Caterham) trade from early, so work is timed around them.

Caterham is about 11 miles south-west of Orpington, in Surrey. Across the CR3 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Commercial mastic work in Caterham

Sealant joints are easy to overlook until one lets water in, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Caterham. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. The enquiries we see most involve smeared sealant across finishes from a rushed job and movement joints packed with grit and debris, across window and door perimeters, kitchen worktops and splashbacks and floor and threshold joints. One point of contact handles commercial sealant work in Caterham from the first photos to the final walk-round, whether it’s one building or several.

If you look after more than one building near Caterham, the work can be planned as one programme, with one quote format and one point of contact.

Smaller commercial landlords and businesses in a town like Caterham often have a handful of sealant jobs that can go on one visit: a frontage, a staff washroom, a kitchen and a few window perimeters, for example. A single fixed quote covers everything on the list.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface

Facade and cladding joints

Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

FAQs: Caterham

What documents will you need to give us for a job in Caterham?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Church Walk Shopping Centre, near Caterham, within your area?

Yes, sites like Church Walk Shopping Centre are within our area, along with the rest of Caterham. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Do you work for facilities managers and managing agents?

Yes. You can send details through our quote form, and tell us what site paperwork you need.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What do you need from us to quote?

Send photographs, drawings or a list of locations. Where we need to see it, we will arrange a site visit, then send a fixed quote.

Can you handle sealant work across several sites?

Yes. We take on runs of jobs across portfolios as well as single sites.

Commercial clients in Caterham

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. In a town such as Caterham, most jobs are single buildings. Your photographs, drawings or a site visit come first, followed by a fixed quote.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  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. Finished joints are checked with you and handed over with our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings

Signs you need commercial sealant contractors in Caterham

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.

Common reasons buildings call us in:

  • Smeared sealant across finishes from a rushed job
  • Shrunken sealant along kitchen worktops and splashbacks
  • External beads that have gone brittle and cracked
  • Wall and floor joints that have lost their seal

If you have premises on more than one site, say at Church Walk Shopping Centre and Brewerstreet Dairy Business Park, one contractor and one quote can cover both.

What to look for in a quote

  • How joint depth will be controlled
  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
  • How long is the guarantee, and what does it include?

Our contractor checklist

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • A dripping trap, valve or pipe behind a fitting
  • Cracking that needs a structural engineer to look at it
  • Roof leaks that only look like a joint problem

If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

What we seal

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