Commercial sealant contractors in Palmer's Green

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. The enquiries we see most involve window and door perimeter joints that have cracked open and weathered facade sealant that no longer flexes, across floor and threshold joints, movement joints in walls and floors and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Palmer's Green, that means joint design, primers and backing rod as standard.

On a typical commercial building in Palmer's Green, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Business units in the countryside around places like Palmer's Green 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 is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Questions about Palmer's Green

Is Palmer's Green too far out for you?

No. Places such as Palmer's Green are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Eldon Way Industrial Estate, near Palmer's Green, within your area?

Yes. We cover Palmer's Green and the area around it, including industrial estates, business parks and retail parks such as Eldon Way Industrial Estate. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Can one contractor look after sealant on all our buildings?

Yes, we can. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we will set out a timescale with the quote.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What guarantee do you give on resealing?

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.

Is the old sealant taken out first?

Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes part of a day on a small job and longer where several buildings or phases are involved, and our waste is bagged and taken away as we go. For work around Palmer's Green, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Warn occupants and staff about the work

Why act early in Palmer's Green

Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation. For buildings around smaller places like Palmer's Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What you get with us

  • 12-month guarantee on workmanship
  • CHAS accredited contractor
  • Over 20 years of commercial sealing
  • Colour options checked against the specified product

Take a look at what affects the cost or how we’re accredited.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Walls or slabs moving more than any sealant can take

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

Surfaces we seal

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

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • The site’s rules and procedures
  • How accessible the joints are
  • Travel to remote or island sites
  • How much there is to seal

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • Clear photographs of the problem areas
  • The product your specification calls for
  • Drawings or a marked-up plan, if available
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email the details over.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Brief cleaning contractors to avoid scourers and blades on sealant
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • On pre-2000 buildings, share the asbestos information before work starts
  • Don’t let cleaning or traffic back on before the cure time is up

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.

Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

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, with colours confirmed for the product chosen.

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing.
